Question 2
Nerves of Branchial arch derived from:
A> Mesoderm
B> Endoderm
C> Neural crest
D> Neuroectoderm
Answer - C
Explanation - Branchial or pharyngeal arches are masses of mesoderm covered by ectoderm and lined by
endoderm. Within these masses, muscular and skeletal components develop, as well as aortic arches and
nerve networks. The arches are separated by grooves, visible on the surface of the embryo as pharyngeal
clefts and in the interior as the pharyngeal pouches
In the human embryo, the arches are first seen during the 4th week of development.
They appear as a series of outpouchings of mesoderm on both sides of developing pharynx.
The neural crest are bilaterally paired strips of cells arising in the ectoderm at the margins of the neural
tube. These cells migrate to many different locations and differentiate into many cell types within the
embryo.
Neural Crest Derivatives
A key feature of neural crest is the migration into other embryonic tissues to form specific neural and non-
neural populations and structures.
Cranial neural crest
migration - dorsolaterally and into pharyngeal arches
craniofacial mesenchyme - cartilage, bone, cranial neurons, glia, and connective tissues of the face
pharyngeal arches and pouches - thymic cells, tooth odontoblasts, middle ear bones (ossicles), stria
vascularis cells, and jaw (mandible)
In the body region, neural crest cells also contribute the peripheral nervous system (both neurons and glia)
consisting of sensory ganglia (dorsal root ganglia), sympathetic and parasympathetic ganglia and neural
plexuses within specific tissues/organs.
In the head region, neural crest cells migrate into the pharyngeal arches forming ectomesenchyme
contributing tissues which in the body region are typically derived from mesoderm (cartilage, bone, and
connective tissue).

B> Keratinised, absent submucosal layer, minor salivary gland
C> Non keratinised, submucosal layer, minor salivary gland
D> Non keratinised, absent submucosa, minor salivary gland
Answer - A
Explanation: The hard palate is located on the roof of the oral cavity, posterior and medial to the alveolar
process of the maxilla.
The bony structure is formed by the palatine processes of the maxilla and the horizontal plates of the
palatine bones.
The periosteum is covered by a firmly attached mucosa centrally, although a submucosa is apparent
laterally containing vessels. The hard palate is continuous with the soft palate posteriorly.
Macroscopic Features
The hard palate is typically a pale pink colour and may have an orange peel appearance from the palatine
salivary glands (more common posteriorly).
Microscopic Features
The hard palate is lined with a keratinising stratified squamous epithelium, tightly bound to the
underlying periosteum of the palatine bone/maxilla. There is minimal submucosa, which becomes more
prominent posteriorly.

Question 5
Ureteric bud develops from:
A> Mesonephros
B> Metanephros
C> Pronephros
D> Genital sinus
Answer- A
Explanation: The ureteric bud, also known as the metanephrogenic diverticulum, is a protrusion from the
mesonephric duct during the development of the urinary and reproductive organs.
It later develops into a conduit (channel) for urine drainage from the kidneys, which, in contrast, originate
from the metanephric blastema.
The metanephrogenic blastema or metanephric blastema (or metanephric mesenchyme, or metanephric
mesoderm) is one of the two embryological structures that give rise to the kidney, the other being the
ureteric bud.
Question 6
About Weber's syndrome which is incorrect:
A> Contralateral hemiplegia
B> Ipsilateral Oculomotor nerve palsy
C> Contralateral Parkinsonism
D> Anterior cerebral peduncle
Answer - D
Explanation:
Weber's syndrome (superior alternating hemiplegia) is a form of stroke characterized by the
presence of an ipsilateral oculomotor nerve palsy and contralateral hemiparesis or hemiplegia.
It is caused by midbrain infarction as a result of occlusion of the paramedianbranches of the
posterior cerebral artery or of basilar bifurcation perforating arteries.
This lesion is usually unilateral and affects several structures in the midbrain:
1. Contralateral parkinsonism because its dopaminergic projections to the basal ganglia innervate
the ipsilateral hemisphere motor field, leading to a movement disorder of the contralateral
body.
2. Contralateral hemiparesis and typical upper motor neuron findings. It is contralateral because
it occurs before the decussation in the medulla.
3. Difficulty with contralateral lower facial muscles and hypoglossal nerve functions.
4. Ipsilateral Oculomotor nerve palsy with a drooping eyelid and fixed wide pupil pointed down
and out. This leads to diplopia.

When Va / Q is infinity?
A> Partial pressure of O2 becomes zero
B> No exchange of O2 & CO2
C> Partial pressure of CO2 alone becomes zero
D> Partial pressure both CO2 and O2 remain normal
Answer: Option B - No exchange of O2 & CO2
Explanation:
Va represents the ventilation in alveoli.
Q represents the blood flow through the alveolus.
The ratio of Va and Q explains the respiratory exchange, when there is imbalance between alveolar
ventilation and alveolar blood flow.
Ventilation-perfusion ratio is considered normal there is equal amount of blood flow & ventilation
through alveolus.
Va /q ratio is Zero - There is inadequate or nil, but perfusion persists
Va /q ratio is infinity - There is adequate ventilation but no perfusion.
Both in Zero and infinity Va /Q ratio, there is no exchange of gases through the respiratory
membranes of corresponding alveoli.
When Va /Q ratio is infinity,
The alveolar air equilibrates the humidified inspired air
No exchange of oxygen and carbon-di-oxide occurs.
Partial pressures of the O2 and CO2 are 149mmHg & 0 mmHg respectively

C> +3D
D> +4D
OR
Q) Astigmatism in emmetropic eye of elderly person contribute to:
A> +1d
B> +2D
C> +3d
D> +4d
Answer C
Explanation:
Laser vision enhancements
When planning presbyopia-correcting IOL(Intra ocular lens) surgery in a patient with a high level of
pre-existing astigmatism (ie, more than 3 D), a bioptics approach (ie, IOL followed by laser vision
enhancement) may be needed.
LRIs alone are unlikely to correct the astigmatism completely.Limbal Relaxing Incisions (LRI) are a
refractive surgical procedure to correct minor astigmatism in the eye.
There are several different strategies for these planned laser vision enhancements. The first is to
perform the presbyopia-correcting IOL surgery followed by LASIK or PRK.
Question 155
100 day Glaucoma seen in which of the following condition:
A> Central retinal vein occlusion (CRVO)
B> Neovascular glaucoma
C> Central retinal artery occlusion (CRAO)
D> Steroid induced Glaucoma
Answer- A
Explanation:
1. 100 days glaucoma is a neovascular glaucoma occurring in CRVO.
2. It consists of occlusion of central retinal vein without significant retinal ischemia.
3. This results in a venous stasis.
4. Recurrent hemorrhages are frequent and neovascularization of retina and optic disc develop.
5. Retina undergoes pigmentary and atrophic changes.
6. Serious complications are cystoid degeneration of macula, optic atrophy and hemorrhagic or
neovascular glaucoma.
7. Hemorrhagic glaucoma is also known as 100 day glaucoma because it starts 3 months after the
episode of central retinal vein occlusion.

Question 158
Severe Conjunctivitis caused by:
A> Neisseria
B> Staphylococcus
C> Streptococcus
D> Haemophilus
ANSWER- A
Explanation:
The most common causes of acute bacterial conjunctivitis are Staphylococcus aureus, Streptococcus
pneumoniae, and Haemophilus influenzae.
Hyperacute cases are usually caused by Neisseria gonorrhoeae or N. meningitidis.
Chronic cases of bacterial conjunctivitis are those lasting longer than 3 weeks, and are typically
caused by Staphylococcus aureus, Moraxella lacunata, or gram-negative enteric flora.
Neisseria gonorrhoeae causes gonococcal conjunctivitis, which usually results from sexual contact
with a person who has a genital infection.
The incidence rates of gonococcal conjunctivitis increase during spring and summer.
This is a potentially devastating ocular infection, because N. gonorrhoeae can cause severe
ulcerative keratitis, which may rapidly progress to corneal perforation.

Question 160
Blow out fracture of orbit involves:
A> Floor
B> Medial wall
C> Lateral wall
D> Roof
Answer-A
Explanation:
Orbital floor fracture, also known as "blowout" fracture of the orbit.
Blow out fracture of orbit involves:
1. Fractures of the orbital floor are common: it is estimated that about 10% of all facial fractures
are isolated orbital wall fractures (the majority of these being the orbital floor), and that 30-40%
of all facial fractures involve the orbit.
2. The anatomy of the orbital floor predisposes it to fracture.
3. The inferior orbital neurovascular bundle (comprising the infraorbital nerve and artery) courses
within the bony floor of the orbit; the roof of this infraorbital canal is only 0.23mm thick, and
the bone of the posterior medial orbital floor averages 0.37 mm thick.
4. By contrast, the bone of the lateral portion of the orbital floor averages 1.25 mm thick, over 5
times the thickness of the bone over the neurovascular bundle. As one might suspect, it is this
very thin area of the orbital floor overlying the neurovascular bundle where isolated orbital
floor fractures invariably occur.
An orbital blowout fracture of the floor of the left orbit.

Question 165.
The following statement about Keloid is true
A>It contain growth factor
B>Extended excision is the treatment of choice
C>It do not extend beyond the wound
D>None of the above
Answer: A
Explanation: Vaccinations, injections, insect bites, ear piercing, or may arise spontaneously.
Keloids tend to occur 3 months to years after the initial insult, and even minor injuries can result in large
lesions.
They vary in size from a few millimeters to large, pedunculated lesions with a soft to rubbery or hard
consistency.
Although they project above surrounding skin, they rarely extend into underlying subcutaneous tissues.
Certain body sites have a higher incidence of keloid formation, including the skin of the earlobe as well as
the deltoid, presternal, and upper back regions.
They rarely occur on eyelids, genitalia, palms, soles, or across joints.
Keloids rarely involute spontaneously, whereas surgical intervention can lead to recurrence, often with a
worse result.

D>Right iliac fossa
C>During feeding
Answer: D
Explanation:
Congenital hypertrophic pyloric stenosis
First born male child is characteristically most commonly affected
It is four times more common in males as in females .
The condition does not present at birth. It is most commonly seen 4 weeks after birth
Presentation
? Vomiting is the presenting symptom (child vomits milk and no bile is present)
? Immediately after vomiting the child is hungry i.e. loss of appetite does not occur.
? Weight loss is striking and rapidly the infant becomes emaciated and dehydrated.
However, greater awareness of pyloric stenosis has led to earlier identification of patients and hence with
fewer incidences of chronic malnutrition and severe dehydration - Nelson 10th/1130
The diagnosis is usually made with a test feed : In this the baby is fed with the bottle by a nurse or
mother and surgeon :
1. palpates the abdomen with a warm hand to detect the lump
2. observes the characteristic peristaltic waves pass across the upper abdomen.
Pathologically musculature of pylorus adjacent to antrum is grossly hypertrophied
Ultrasonography is the investigation of choice
Hyperchloremic alkalosis is common and following diagnosis first concern is to correct metabolic
abnormalities -child is rehydrated with dextrose saline and potassium
Treatment of choice Ramstedt's operation - 'Pyloromyotomy'

Question 192
In pregnancy which of the following level is altered mostly:
A. TSH
B. Free T3
C. Free T4
D. T3 binding globulin
Ans C.TSH
Explanation:
Increased blood concentrations of T4-binding globulin: TBG is one of several proteins that transport
thyroid hormones in blood, and has the highest affinity for T4 (thyroxine) of the group. Estrogens
stimulate expression of TBG in liver, and the normal rise in estrogen during pregnancy induces
roughly a doubling in serum TBG concentration.
Increased levels of TBG lead to lowered free T4 concentrations, which results in elevated TSH
secretion by the pituitary and, consequently, enhanced production and secretion of thyroid
hormones

Question. 211
Murphy's eye is seen in
A> Macintosh laryngoscope
B> Endotracheal tube
C> LMA
D> Flexible laryngoscope
Answer: Option B - Endotracheal Tube
Explanation:
The "Murphy eye" is the eponymous name for a hole on the side of most endotracheal tubes
(ETTs) that functions as a vent, and prevents the complete obstruction of the patient's airway,
should the primary distal opening of an ETT become occluded
Question. 212
Modified MallamPati grading is used in assessment of
A> Difficult intubation
B> Airway obstruction
C> Death due to aspiration
D> Intubation
Answer: Option A - Difficulty in intubation
Explanation:
Modified Mallampati classification
Class 0: Ability to see any part of the epiglottis upon mouth opening and tongue protrusion
Class I: Soft palate, fauces, uvula, pillars visible
Class II:Soft palate, fauces, uvula visible
Class III: Soft palate, base of uvula visible
Class IV: Soft palate not visible at all
Test: The assessment is performed with the patient sitting up straight, mouth open and tongue
maximally protruded, without speaking or saying "ahh."
Predictive value of modified Mallampati classification
Difficult laryngoscopy:Good accuracy (area under Summary Receiver Operating Characteristic
[SROC] curve 0.89 ? 0.05)
Difficult intubation: Good accuracy (area under SROC curve 0.83 ? 0.03)
Difficult mask ventilation: Poor predictor
Used alone, the Mallampati tests have limited accuracy for predicting the difficult airway and thus
are not useful screening tests
Mallampati classification is only one of 11 nonreassuring findings during airway examination
Question. 213
Which nerve is tested for adequacy of anaesthesia
A> Median Nerve
B> Ulnar Nerve
C> Radial nerve
D> Mandibular nerve
Answer: Option A - Median nerve
Explanation:
Median nerve block can be evaluated by testing the lateral aspect of the ring finger
Question.214
Most effective circuit in spontaneous anaesthesia is
A> Mapleson A
B>Mapleson B
C> Mapleson C
D> Mapleson D
Answer: Option A - Mapleson A
Explanation:
MAPLESON A - (Magill) CIRCUIT
Useful in spontaneous ventilation
The patient inspires whatever is in the tube, using the bag as a volume reservoir.
On eated tube and incoming fresh gas. When the bag is full, exhaled alveolar gas is vented
frxpiration, the bag refills from a combination of expired gas going back up the corrugom
the exhale valve, and then during any expiratory pause, FGF pushes the remaining alveolar
gas out.
Theoretically FGF = 0.7 x Valv should prevent significant rebreathing because deadspace gas
(fresh) is not wasted, but FGF = VA more reliably prevents rebreathing.
Tube volume must exceed (Vt-Vd) or alveolar gas could contaminate the bag.
Inadequate FGF causes rebreathing . Difficult to detect from the CO2 waveform alone - all
that happens is that the rapid fall on inspiration is delayed. If VA exceeds tubing volume,
CO2 enters the bag and will be seen on inspiration on the capnogram.
Controlled ventilation
If the anaesthetist fully closed the valve while squeezing the bag and didn't open it until just
before the bag filled, this circuit would be OK. More commonly the valve is partially closed -
enough to permit adequate tidal volumes despite parallel loss of gas out the valve. FGF must
be increased to compensate for gas lost during inspiration - typically 2.5x minute ventilation.
The Lack system
A co-axial Magill, with the expiratory valve brought coaxially back to the Fresh Gas outlet.
Not popular due to inefficiency during controlled ventilation.
Question. 215
What is mechanism of action of Curanium drugs as muscle relaxant?
A> Persistently depolarizing at Neuromuscular junction
B> Act competitively on Ach receptors blocking post-synaptically
C> Repetitive stimulation of Ach receptors on muscle end plate
D> Inhibiting the calcium channel on presynaptic membrane
Answer: Option B - Act competitively on Ach receptors blocking post-synaptically
Explanation:
Candocuronium iodide is an aminosteroid neuromuscular-blocking drug or skeletal muscle
relaxant in the category of non-depolarizing neuromuscular-blocking drugs.
Acts on Ach receptors competitively post-synaptically blocking them.
Potential adjunctive use in anaesthesia to facilitate endotracheal intubation & provide skeletal
muscle relaxation.
Candocuronium demonstrated a short duration and a rapid onset of action, with little or no
ganglion blocking activity, and it was only slightly less potent than pancuronium

papules , blisters or vesicles etc . The differential features are
It is confined to the area where the trigger touched the zone,
It occurs after a day or two of the exposure and
The symptoms reappear when in contact with the allergen .
Radio
Question 219
Dye used in diagnosis of esophageal perforation:
A> Iohexol
B> Barium sulphate
C> Gadolinium
D> Iodine dye
Answer-B
Explanation:
Barium sulfate in suspension is frequently used medically as a radiocontrast agent for X-ray
imaging and other diagnostic procedures.
It is most often used in imaging of the GI tract during what is colloquially known as a "barium meal".
Fluoroscopy
most sensitive within the first 24 hours.
patient examined semi-supine (~20 degrees) on fluoroscopy table
a water-soluble agent should be used initially as barium can cause mediastinitis
esophageal perforation may be represented as mucosal irregularity or gross extraluminal contrast
extravasation
some authors suggest the use of small amounts of low or high concentrations of barium if no leak is
evident on initial screening with water soluble contrast
Iohexol, trade names Omnipaque among others, is a contrast agent used during X-rays.This includes when
visualizing arteries, veins, ventricles of the brain, the urinary system, and joints, as well as during computer
tomography. It is given by mouth, injection into a vein, or into a body cavity.
Question 220
Bragg peak effect pronounced in:
A> X ray
B> Proton
C> Neutron
D> Electron
Answer- B
Explanation:
Bragg peak
Pronounced peak on the Bragg curve which plots the energy loss ofionizing radiation during its
travel through matter.
Forprotons,-rays, and otherion rays, the peak occurs immediately before the particles come to
rest. This is called Bragg peak, afterWilliam Henry Bragg who discovered it in 1903.
Bragg curve
Typical for heavy charged particles and describes energy loss of ionizing radiation during travel
through matter.
For this curve is typical the Bragg peak, which is the result of 1/v2 dependency ofthe stopping
power. This peak occurs because thecross section of interaction increases immediately before the
particle come to rest. For most of the track, the charge remains unchanged and the specific energy
loss increases according to the 1/v2.
Bragg Curve is typical for heavy charged particles and plots the energy loss during its travel through matter.
Question 221
Salt and Pepper pot appearance of skull seen in:
A> Hyperparathyroidism
B> Multiple myeloma
C> Hyperthyroidism
D> Pseudo hyperparathyroidism
Answer- A
Explanation:
Pepperpot skull is occasionally used in place of salt and pepper skull to describe the typical
radiographic appearance of multiple small radiolucent lesions of the skull vault.
In primary hyperparathyroidism, extensive resorption bone in the skull in combination with cystic
areas of osteopenia are termed pepper pot skull.
Classically seen in hyperparathyroidism, and is occasionally used (inaccurately) to describe the
raindrop skull of multiple myeloma.
Question 222
Imaging techniques used in Uterus anomalies EXCEPT:
A> HSG
B> MRI guided HSG
C> CT guided HSG
D> USG
Answer C
Explanation:
Imaging studies, such as a hysterosalpingogram (HSG) and ultrasound, or an MRI are required to
visualise the uterus and confirm that a congenital uterine anomaly is present.
A hysterosalpingogram is not considered as useful due to the inability of the technique to evaluate
the exterior contour of the uterus and distinguish between a bicornuate and septate uterus.
In addition,laparoscopy and/orhysteroscopy may be indicated.
Question 223
Spot radiograph from a double contrast esophagram. Image represents:
A> Esophageal atresia
B> Esophageal stenosis
C> Feline oesophagus
D> Tracheoesophageal fistula
Answer- C
Explanation:
In given image, there are numerous 1-2 mm radiolucent folds across the oesophagus. The folds are angled
with respect to the center of the oesophagus in a "herringbone" pattern.
The folds occur transiently.
Feline oesophagus also known as oesophageal shiver, refers to the transient transverse bands seen in the
mid and lower oesophagus on a double contrast barium swallow.
The appearance is almost always associated with active gastro-oesophageal refluxand is thought to be due
to contraction of the muscularis mucosae with resultant shortening of the oesophagus and 'bunching up' of
the mucosa in the lumen.
Radiographic features
The folds are 1-2 mm thick and run horizontally around the entire circumference of the oseophageal
lumen. The findings are transient, seen following reflux and not during swallowing. The appearance is
confined to the distal two-thirds of the thoracic oesophagus.
Question 224
MRI of skull represents:
A> Vein of Galen
B> Dandy walker Syndrome
C> Pneumocephalus
D> Crouzon syndrome
Answer A
Explanation:
The vein of Galen is located under the cerebral hemispheres and drains the anterior and central regions of
the brain into the sinuses of the posterior cerebral fossa.
The vein of Galen, also known as the great cerebral vein or great vein of Galen, is a short trunk formed by
the union of the two internal cerebral veins and basal veins of Rosenthal. It lies in the quadrigeminal
cistern. It curves backward and upward around the posterior border of the splenium of the corpus
callosum to drain into the confluence of the inferior sagittal sinus and the anterior extremity of the straight
sinus.
Question 225
What is diagnosis based on given image:
A> Uterus didelphys
B> Bicornuate Uterus
C> Unicornuate Uterus
D>Septate uterus
Answer-C
Explanation:
A unicornuate uterus or unicornis unicollis is a type of Mullerian duct anomaly (class II) that is the
second most commonly associated with miscarriages.
This type can account for ~10% (range 6-13%) of uterine anomalies and infertility is seen in ~12.5%
(range 5-20%) of cases.
Above image unicornuate uterus as seen on a hysterosalpingogram represents:
The endometrial cavity usually assumes a fusiform (banana type) shape (except for type a where there may
a small cavitation filling defect), tapering at the apex and draining into a single fallopian tube. The uterus is
generally shifted off the midline.
Question 226
X ray of skull showing which lesions in brain:
A> Paget's disease
B> Multiple myeloma
C> Osteosarcoma
D> Osteomyelitis
Answer- A
Explanation:
Paget diseaseof the bone is a common, chronic bone disorder characterised by excessive abnormal bone
remodelling. It frequently affects the pelvis, spine, skull and proximal long bones and has characteristic
radiographic features.
Radiographic features
The early phase features osteolytic (lucent) region which is later followed by coarsened trabeculae and
bony enlargement. Sclerotic changes occur much later in the disease process.
osteoporosis circumscripta: large, well-defined lytic lesion
cotton wool appearance: mixed lytic and sclerotic lesions of the skull
diploic widening: both inner and outer calvarial tables are involved, with the former usually more
extensively affected
Tam o'Shanter sign: frontal bone enlargement, with the appearance of the skull falling over the
facial bones, like a Tam o' Shanter hat.
( Thickened diploe of the skull and ill-defined 'fluffy' sclerotic areas most pronounced in the frontal bone.)
Question 227
CT of Thorax represents:
A> Ascending Aortic dissection
B> Descending Aortic dissection
C> Aortic aneurysm
D> Cystic fibrosis
Answer B
Explanation:
Aortic dissection (AD) occurs when an injury to the innermost layer of the aorta allows blood to flow
between the layers of the aortic wall, forcing the layers apart.
The diagnosis of aortic dissection is based on clinical suspicion combined with imaging studies. Chest x-ray
will sometimes show a "widened mediastinum". This occurs because the enlarged aorta casts a larger
shadow on the x-ray detector. If this is seen, and there is a high clinical suspicion of a dissection, a CT scan
of the chest with intravenous contrast is ordered (see image).
The CT scan will show the true and false lumens associated with dissection.
Question 228
CT scan of abdomen showing an area that branching into the liver. Identify the structure ?
A> SVC
B> IVC
C> Portal vein
D> Splenic vein
Answer- C
Explanation:
The portal vein or hepatic portal vein is a blood vessel that carries blood from the gastrointestinal
tract, gallbladder, pancreas and spleen to the liver.
This blood contains nutrients and toxins extracted from digested contents. Approximately 75% of
total liver blood flow is through the portal vein, with the remainder coming from the hepatic artery
proper. The blood leaves the liver to the heart in the hepatic veins.
Question 229
Identify artery `X' in the given angiography anatomy image:
A> Superior mesenteric artery
B> Subclavian artery
C> Celiac artery
D> Brachiocephalic artery
Answer ? A
Explanation:
The superior mesenteric artery (SMA) is a major artery of the abdomen. It arises from the abdominal aorta,
and supplies arterial blood to the organs of the midgut ? which spans from the major duodenal papilla (of
the duodenum) to the proximal 2/3 of the transverse colon.
Anatomical Position
The superior mesenteric artery is the second of the three major anterior branches of the abdominal aorta
(the other two are the coeliac trunk and inferior mesenteric artery). It arises anteriorly from the abdominal
aorta at the level of the L1 vertebrae, immediately inferior to the origin of the coeliac trunk.
After arising from the abdominal aorta, the superior mesenteric artery descends down the posterior aspect
of the abdomen. At this point, it has several important anatomical relations:
Anterior to the SMA ? pyloric part of the stomach, splenic vein and neck of the pancreas.
Posterior to the SMA ? left renal vein, uncinate process of the pancreas and inferior part of the
duodenum.
The uncinate process is the only part of the pancreas that hooks around the back of the
SMA.
Major Branches
The superior mesenteric artery then gives rise to various branches that supply the small
intestines, cecum, ascending and part of the transverse colon (fig).
The superior mesenteric artery and its branches.
Psychiatry
Question. 230
Semen squeeze
A>Erectile dysfunction
B> Premature ejaculation
C> Retrograde ejaculation
D> Antegrade ejaculation
Answer: Option B- Premature Ejaculation
Explanation:
Squeeze Technique:
Variation of the Masters and Johnson method.
As a man approaches climax, either he or his partner squeezes the tip of the penis just
below the head of the penis as he approaches the point of climax.
Pressure is held there until the sensation of impending orgasm diminishes.
This pressure can even be held until there is some reduction in erection.
The process can then be started over again so that over time a man prolongs the time
period until he reaches ejaculation.
Useful to treat cases of premature ejaculation
Question. 231.
A patient with a history of RTA before 2 months presents with complaints of dreams of accidents. He is
able to visualize the same scene whenever he visits the place. Hence is afraid to go back to the accident
site. Identify the type of disorder that he might be suffering from?
A> Adjustment disorder
B> PTSD
C> Anxiety disorder
D> OCD
Answer: Option B - Post-traumatic Stress disorder
Explanation:
Post-traumatic stress disorder, basically a type of anxiety disorder
Though it shares features with other anxiety disorders, has its own specific characteristics in
presentation.
Criteria 1:
Etiologically significant trauma should be present to be classified under this condition.
Criteria 2:
"Intentionality" or "aboutness", an important factor in PTSD.
PTSD concerns with memory intrusion of past stressors into present.
Nightmares, flashbacks, or reliving experiences should be related to the past experience.
Criteria 3:
Avoid a stimulus or activity that provokes the memory of past event.
Question. 232
Freud's theory of dream includes all except:
A> Displacement
B> Condensation
C> Symbolisation
D> Correlation
Answer: Option -D - Correlation
Explanation:
Sigmund Freud theory of dream:
Dream work involves the process of condensation, displacement, and secondary elaboration.
Concept of unconscious mind:
Primary assumption of Freudian theory is that the unconscious mind governs behavior to a
greater degree than people suspect.
Goal of psychoanalysis is to make the unconscious, conscious.
Theory of dream:
Freud theory of dream elaborates the state of unconscious mind with respect to dream
interpretation,
Process involved include condensation, displacement, and secondary elaboration.
Displacement takes place when we transform the person or object we are really concerned
about to someone else.
The process of condensation is the joining of two or more ideas/images into one.

reliving the experience that caused it.
Done typically through
Hypnosis
Suggestion
Question.234
All are habit disorder except
A> Nail biting
B> Thumb sucking
C> Temper tantrum
D> Tics
Answer: Option C- Temper tantrum
Explanation:
Definition:
Habit disorder is a term used to describe several related disorders linked by the presence of
repetitive and relatively stable behaviour that seem to occur beyond the awareness of the
person performing the behaviour.
The first group of habit disorder includes "Tic Disorder"
Tics are involuntary movements, sounds, or words that are sudden, rapid, recurrent and non-
rhythmic"
In addition to TD's, body-focussed behaviours,
Recurrent hair pulling - Trichotillomania (TTM)
Skin picking (SP)
Nail biting , are included within habit disorders.
Head banging, rocking of body, teeth grinding & thumb sucking are repetitive disorders.
Seen in children between age group of 6 months to 2 years.
Benign & self-limited.
The movements serve a means of tension discharging in children.
As children become older, they learn to inhibit some of their rhythmic patterns.
Undue attention by parents can lead to aggravation of these problems.

Question 237
A 55 years aged chronic alcoholic male, presented with irrelevant talks, tremor and sweating. He had his
last drink 3 days back. What will the probable diagnosis?
A> Delirium tremens
B> Korsakoff psychosis
C> Post-Acute withdrawal syndrome
D> Discontinuation syndrome
Answer: Option A - Delirium Tremens
Explanation:
The description of symptoms is related to the condition "Delirium Tremens"
Delirium Tremens / Alcohol Withdrawal Delirium (AWD):
Most severe form of ethanol withdrawal manifested by,
Altered mental status (Global confusion)
Autonomic hyperactivity (Sympathetic overdrive)
Mechanism:
Alcohol abuse affects neurotransmitter systems in brain mainly by,
Loss of GABA inhibitory mechanism - Reduces chloride ion influx.
Alcohol acts as NMDA receptor antagonist - Withdrawal increases the excitatory
neurotransmitter.
The clinical manifestations of ethanol withdrawal are combination effects of GABA & NMDA
receptor activity.
Thus causing tremors, diaphoresis, tachycardia, anxiety & in severe cases Seizure.
Question 238.
Which of the following is carrying agent for the disease with given characteristic on polarized
microscopy?
A> Anopheles
B>Ixodes scapularis ticks
C> Louse
D> Rat flea
Answer: B
Explanation:
Babesiosis infects the RBCs and resides inside the RBCs ( intraerythrocytic).
Intraerythrocytic infection of Babesiosis is characterised by maltese cross.
Maltese cross is a characteristic arrangement of parasites within the erythrocytes --->Parasites
within erythrocytes are arranged such that pointed ends of four parasites come in contact thereby
giving a tetrad configuration resembling a maltese cross.
Tetrad forms or 'Maltese cross' appearance is considered pathognomic of Babesiosis.
Babesiosis can easily be confused with P. falciparum malaria.Following two features distinguish
Babesiosis from malaria
1. Presence of maltese cross in Babesiosis ( absent in malaria)
2. Absence of pigment Hemozoin in Babesiosis ( present in malaria)
Note - Maltese cross is also seen in cryptococcus and aspergillus.

B>Reversed saphenous
C>PTFE
D>None
Answer: C- PTFE-covered self-expanding nitinol stents
Explanation:
PTFE-covered stents are engineered with a 30?100 micron pore size to allow for endothelial lining
of the stent-graft and vessel healing.
Only self-expanding covered nitinol stents should be used in femoropopliteal interventions.
Question 240
Trilene is degraded by:
A>Enzymatic Degradation
B>Non Enzymatic degradation
C>Chemical Degradation
D>None
Answer:A
Explanation:
Trilene or trichloroethylene is a good analgesic, less depressant, and non-flammable.
Cardiac dysrhythmia, or tachypnoea may occur during administration.
It should not be used in the closed circuit as it reacts with soda-lime to produce a toxic
gas(phosgene).
Recovery is slow and nausea as well as vomiting may be present.
It should not be used with adrenaline infiltration lest dysrhythmia be converted to ventricular
fibrillation.
Degradation:
Brought about by enzymatic degradation
The enzyme that starts one branch of this pathway, toluene 1,2-dioxygenase, has many other
catalytic abilities, which are documented in a table of the Reactions of Toluene 1,2-Dioxygenase.
The spontaneous degradation of trichloroethylene epoxide can produce as many as four products:
dichloroacetate, carbon monoxide, glyoxylate, and formate. The number, type, and proportion of
products seen depends on the local environment.
Question 241.
The earliest feature of 3rd cranial nerve involvement in diabetes mellitus patient is
A>Normal light reflex
B>Abnormal light reflex
C>Normal light and accommodation reflex
D>Abnormal light and accommodation reflex
Answer:A
Explanation: The oculomotor nerve is the third cranial nerve. It enters the orbit via the superior orbital
fissure and innervates muscles that enable most movements of the eye and that raise the eyelid. The nerve
also contains fibers that innervate the muscles that enable pupillary constriction and accommodation
(ability to focus on near objects as in reading). The oculomotor nerve is derived from the basal plate of the
embryonic midbrain.In people with diabetes and older than 50 years of age, an oculomotor nerve palsy
occurs.
Question 242
During squint surgery, anesthesiologist sees the machine and see the bp suddenly drops to 40. What will
be best immediate management
A>Give atropine
B>Increase level of anesthesia
C>Ask the surgeon to stop the surgery
D>Give adrenaline
Answer: D
Explantation: adrenaline should be given to raise the blood pressure.
Epinephrine, also known as adrenalin or adrenaline, is a hormone, neurotransmitter, and medication.
Epinephrine is normally produced by both the adrenal glands and certain neurons.
It plays an important role in the fight-or-flight response by increasing blood flow to muscles, output of
the heart, pupil dilation, and blood sugar. It does this by binding to alpha and beta receptors.
Physiologic responses to epinephrine by organ

All are special visceral efferent column except
A>Glossopharyngeal n
B>Nucleus ambiguus
C>vagus nerve
D>trigeminal nerve
Answer: B
Explanation: Special visceral efferent fibers (SVE) are the efferent nerve fibers that provide motor
innervation to the muscles of the pharyngeal arches in humans,The only nerves containing SVE fibers are
cranial nerves: the trigeminal nerve (V), the facial nerve (VII), the glossopharyngeal nerve (IX), the vagus
nerve (X) and the accessory nerve
Question 244.
Which of the following condition is NOT caused by Parvovirus B19?
A>Roseola infantum
B>Aplastic anemia in sickle cell disease
C>Fetal hydrops
D>Erythema infectiosum
Answer: A
Explanation:
Primary infection by parvovirus B19 often produces an acute, severe, and sometimes fatal anemia
manifested as a rapid fall in red blood cell count and hemoglobin.
These patients may present initially with no clinical symptoms other than fever; this is commonly referred
to as aplastic crisis.
Erythema infectiosum (also referred to as fifth disease or academy rash) is a more common disease that is
clearly attributable to parvovirus B19.
Active transplacental transmission of parvovirus B19 can occur during primary infections in the first 20
weeks of pregnancy, sometimes resulting in stillbirth of fetuses that are profoundly anemic.
The progress can be so severe that hypoxic damage to the heart, liver, and other tissues leads to extensive
edema (hydrops fetalis).

A red soft to firm swelling on sternum that on biopsy shows following histology. What is the diagnosis?
A. Hemangioma
B. Osteochondroma
C. Osteoid osteoma
D. Paget disease
Ans. A. Hemangioma
Explanation:
Clinical presentation
These tumours are slow growing and are generally asymptomatic unless they exert mass effect on sensitive
structures. Occasionally they may present as a swelling or a palpable mass, especially in the skull. When
large and strategically located they may present with a pathological fracture.
If they are high-flow lesions, shunt-related symptoms may also be present.
Pathology
Primary intraosseous haemangiomas are slow growing vascular neoplasms, usually located in the
medullary cavity. They are classified as benign, but rarely may be locally aggressive.
Histology
Histologically, intraosseous haemangiomas demonstrate hamartomatous vascular tissue within
endothelium, but may also contain fat, smooth muscle, fibrous tissue, and thrombi.
Question:255
What differentiates delirium from dementia?
A. Confusion
B. Difficulty in communicating
C. Hallucination
D. Sudden change
Answer:D
Explanation:
Delirium
Also called the acute confusional state, delirium is a medical condition that results in confusion and other
disruptions in thinking and behavior, including changes in perception, attention, mood and activity level.
In dementia, changes in memory and intellect are slowly evident over months or years. Delirium is a more
abrupt confusion, emerging over days or weeks, and represents a suddenchange from the person's
previous course of dementia. Thinking becomes more disorganized, and maintaining a coherent
conversation may not be possible.
The hallmark separating delirium from underlying dementia is inattention. The individual simply cannot
focus on one idea or task.
Question:256

A. Tenofovir disoproxil fumarate with emtricitabine
B. Tenofovir disoproxil fumarate with lamivudine
C. Abacavir with lamivudine
D. All
Ans. D. All
Explanation: Preferred Regimens for HIV Antiretroviral Therapy (ART) in Pregnancy
Two-NRTI backbone
Regimens include the following:
Tenofovir disoproxil fumarate with emtricitabine (TDF/FTC co-formulated) or tenofovir
disoproxil fumarate with lamivudine (3TC) once daily (use with caution in renal insufficiency)
or
Abacavir with lamivudine (ABC/3TC) once daily (only if HLA-B5701?negative); avoid
combination with ritonavir-boosted atazanavir if the pretreatment HIV viral load exceeds
100,000 copies/mL.
For women who have never taken HIV medicines, the preferred HIV regimen should include two
nucleoside reverse transcriptase inhibitors (NRTIs) plus an integrase strand transfer inhibitor (INSTI), a
non-nucleoside reverse transcriptase inhibitor (NNRTI), or a protease inhibitor (PI) with low-dose
ritonavir (brand name: Norvir).
The regimen generally should include at least one of the following NRTIs that pass easily across the
placenta:
abacavir (brand name: Ziagen)
emtricitabine (brand name: Emtriva)
lamivudine (brand name: Epivir)
tenofovir disoproxil fumarate(brand name: Viread)
zidovudine (brand name: Retrovir)
Question: 258
Which of the following structure develops from dorsal mesentery?
A. Greater omentum
B. Lesser omentum
C. Liver
D. Diaphragm
Ans. A.
Explanation:
The portion of the dorsal mesentery that attaches to the greater curvature of the stomach, is known as the
dorsal mesogastrium. The part of the dorsal mesentery that suspends the colon is termed the mesocolon.
The dorsal mesogastrium develops into the greater omentum.
Question 259:
What is the structure seen in the given X-ray below?
A. Stent
B. Surgical clips
C. Foley catheter
D. Intravesical wire
Ans. A. Stent
Explanation:
Plain abdominal X ray showing a stent in the right and left ureter.
Ureteric stents,also known as double J stents or retrograde ureteric stents, is a urological catheter that
has two "J-shaped" (curled) ends, where one is anchored in the renal pelvis and the other inside the
bladder.
Stents are used for the free passage of urine from the kidney to the bladder, in adverse conditions such as
postoperative urologic procedures, and previously to lithotripsy and ureteral obstructions.
Indications
Stents may be uses for a short of long term period depending on the indication:
obstruction from urolithiasis
malignant obstruction (typically pelvic malignancies)
benign strictures
retroperitoneal fibrosis
bilateral ureteric stents
Question 260:
What is the diagnosis based on the following X-ray?
A. Uterine Fibroid
B. Bladder Carcinoma
C. Bladder stone
D. Renal Tuberculosis
Ans. C. Bladder stone
Explanation:
Multiple bladder calculi. Four oval radiopaque bladder stones are visible centrally in the pelvis. Most
bladder calculi are round or oval, but they may also be amorphous, laminated, or even spiculated.
Bladder stones are small mineral deposits that can form in the bladder. In most cases bladder stones
develop when the urine becomes very concentrated or when one is dehydrated.
This allows for minerals, such as calcium or magnesium salts, to crystallize and form stones.
In some cases bladder stones do not cause any symptoms and are discovered as an incidental finding on a
plain radiograph.
Bladder stones vary in their size, shape and texture- some are small, hard and smooth whereas others are
huge, spiked and very soft. One can have one or multiple stones. Bladder stones are somewhat more
common in men who have prostate enlargement. The large prostate presses on the urethra and makes it
difficult to pass urine. Over time, stagnant urine collects in the bladder and minerals like calcium start to
precipitate.
Radiography
The initial imaging study of choice is plain radiography of the kidneys, ureters, and bladder (KUB), which is
the least expensive and easiest radiologic test to obtain. Pure uric acid and ammonium urate stones are
radiolucent but may be coated with a layer of opaque calcium sediment. Laminations are common, with
the layers stratified according to metabolic and infectious status and the degree of periodic hematuria (see
the images below).
Multiple laminated bladder calculi in patient with neurogenic bladder.
Question 261:
By which method foreign DNA is introduced into a cell by a virus or viral vector?
A. Transduction
B. Transcription
C. Lysogenic conversion
D. Transformation
Ans. A. Transduction
Explanation:
Transduction is the process by which foreign DNA is introduced into a cell by a virus or viral vector. An
example is the viral transfer of DNA from one bacterium to another.
Question 262:
Which one of the following shows allosteric inhibition?
A. Malonic acid & succinate
B. 2,3 BPG
C. Amino acid alanine & pyruvate kinase
D. Citrate
Answer:B
Explanation:
Negative allosteric modulation (also known as allosteric inhibition) occurs when the binding of one ligand
decreases the affinity for substrate at other active sites. For example, when 2,3-BPG binds to an allosteric
site on hemoglobin, the affinity for oxygen of all subunits decreases.
Question 263:
Which of the following is seen in seropositive rheumatoid arthritis?
A. Multiple joints affected

Question 265:
Struvite stone is caused by which metal?
A> Magnesium
B> Calcium
C> sodium & potassium
D> both (a) & (b)
Ans. Magnesium
Explanation:
Struvite, a crystalline substance is composed of magnesium ammonium phosphate (MgNH4PO4 ? 6H2O).
Struvite urinary stones have also been referred to as "infection stones" and "triple phosphate" stones.
Struvite stones can be caused by alkaline urine, steroid therapy, abnormal retention of urine, a urinary
tract infection, or another disorder of the urinary tract.
There are five primary types of commonly encountered urinary stones, i.e., calcium oxalate, calcium
phosphate, magnesium ammonium phosphate, uric acid, and cystine.
Question 266:
Which of the following statements about Graves disease is false?
A> Results in hyperthyroidism
B> Autoimmune disorder
C> Common in Male
D> Referred as Toxic diffuse goitre
Ans. Option C - Common in male
Explanation:
Graves' disease:
Autoimmune system disorder
Both men and women get affected;
Yet, 10 times more common in women than men
Affects younger women < 40 years
Results in overproduction of thyroid hormones (hyperthyroidism).
Signs and symptoms:
Anxiety
Irritability
Heat sensitivity
Increased perspiration/ warm and moist skin
Weight loss
Goiter (Glandular enlargement)
Menstrual cycle changes
Erectile dysfunction/ reduced libido
Graves Ophthalmopathy - Bulging eyes - Exophthalmos
Graves dermopathy - Thick, red skin on shins / top of feet.
Antibody for graves disease - Thyrotropin receptor antibody (TRAb) acts on the regulatory
pituitary hormone interfering the normal secretion of thyroxine.
TRAb overrides normal regulation causing an overproduction of thyroid hormones
(hyperthyroidism).
Question 267:
Aldosterone synthesis is stimulated by which of the following?
A.ACTH
B. Hyperkalemia
C.Hypernatremia
D.Exogenous steroids
Ans. B
Explanation:
Mineralocorticoid secretion is stimulated by hyperkalemia, angiotensin-H, ACTH and hyponatremia, in
reducing order of efficacy.
1. Aldosterone secretion in response to hyperkalemia is the most important and forms the basis for
renal regulation of body potassium balance.
2. Stimulation of aldosterone by angiotensin II (through renin-angioensin system) is important for the
correction of hypovolemia and hypotension in conditions like salt depletion or renal ischemia.
3. Stimulation of aldosterone secretion by ACTH results in diurnal variation of aldosterone secretion.
4. However, ACTH is not an important physiological regulator for aldosterone secretion.
Hyponatremia is a weak stimulator of aldosterone secretion
Question 268
Which of the following is false about Alzheimer's disease?
A. One in 10 people age 65 and older has Alzheimer's disease.
B. Alzheimer's disease is curable.
C. Cause dementia
D. All of the above
Ans. B
Explanation: Alzheimer's disease Also called: senile dementia. A progressive disease that destroys
memory and other important mental functions.
Memory loss and confusion are the main symptoms.
Currently, there is no cure for Alzheimer's. But drug and non-drug treatments may help with both
cognitive and behavioral symptoms.
The treatments available for Alzheimer's do not slow or stop the progression of the disease, but they may
help with the symptoms for a time.
There are three cholinesterase inhibitors to treat Alzheimer's:
Donepezil (Aricept)
Rivastigmine (Exelon)
Galantamine (Reminyl)
People may experience:
Cognitive: mental decline, difficulty thinking and understanding, confusion in the evening hours,
delusion, disorientation, forgetfulness, making things up, mental confusion, difficulty concentrating,
inability to create new memories, inability to do simple maths, or inability to recognise common
things
Behavioural: aggression, agitation, difficulty with self care, irritability, meaningless repetition of
own words, personality changes, restlessness, lack of restraint, or wandering and getting lost
Mood: anger, apathy, general discontent, loneliness, or mood swings
Psychological: depression, hallucination, or paranoia
Also common: behavioral symptoms, inability to combine muscle movements, jumbled speech, or
loss of appetite
Question 269
Which of the following is true about vitamin K?
A> anticoagulant
B> Prolong use of antimicrobial leads to deficiency
C> dietary allowance is 15-20 mg
D> all of the above
Ans. Prolong use of antimicrobial leads to deficiency
Explanation:
Certain people are at increased risk if they:
take coumarin anticoagulants such as warfarin, which thins the blood
are taking antibiotics
have a condition that causes the body to not absorb fat properly (fat malabsorption)
have a diet that is extremely lacking in vitamin K
Vitamin K is a group of structurally similar, fat-soluble vitamins the human body requires for complete
synthesis of certain proteins that are prerequisites for blood coagulation and which the body also needs for
controlling binding of calcium in bones and other tissues
The body needs vitamin K to produce prothrombin, a protein and clotting factor that is important in blood
clotting and bone metabolism.
Without vitamin K, blood coagulation is seriously impaired, and uncontrolled bleeding occurs. Preliminary
clinical research indicates that deficiency of vitamin K may weaken bones, potentially leading to
osteoporosis, and may promote calcification of arteries and other soft tissues
Dietary allowance for adults per day- 50-100 mg.
Question 270
Which drugs needs continuous monitoring of prothrombin time?
A.Aspirin
B.Lepirudin
C.Digoxin
D. Coumadin
Ans.D
Explanation: Coumadin (warfarin) is an anticoagulant.
Warfarin is a coumarin anticoagulant used for the prophylaxis and treatment of thromboembolic
complications associated with cardiac valve replacement and atrial fibrillation,as well as the prophylaxis
and treatment of venous thrombosis and pulmonary embolism.Increased metabolism of warfarin results in
insufficient prolongation of prothrombin time.
Question 271
Which of the following are the risk factor for cutaneous lymphoma?
A> Age
B> Gender
C> Weakened immune system
D> All
Answer:D
Explanation:
Risk Factors for Lymphoma of the Skin
Age Age is an important risk factor for this disease, with most cases occurring in people in their 50s and
60s. But some types of skin lymphoma can appear in younger people, even in children.
Gender and race Most (but not all) types of skin lymphoma are more common in men than in women.
Most also tend to be more common in African-Americans than in whites. The reasons for this are not
known.
Weakened immune systemSkin lymphomas may be more common in people with acquired
immunodeficiency syndrome (AIDS), who have a weakened immune system. They may also be more
common in people who have had an organ transplant such as a heart, kidney or liver transplant. These
people must take drugs that suppress their immune system, which may raise the risk of skin lymphoma (or
lymphomas in other parts of the body).
Infections Infection with the human immunodeficiency virus (HIV), the virus that causes AIDS, may
increase a person's risk of skin lymphoma.
Question 272:
Which is not included in AIDS related complex?
A. Ectopic pregnancy
B. Recurrent genital candidiasis
C. Generalised lymphadenopathy
D. Chronic diarrhea
Answer- A
Explanation: HIV symptoms: AIDS related complex (ARC)
It belongs to class B of HIV symptoms. The patients at this stage have various diseases that occur because
the HI virus has weakened the immune system.
The following HIV signs may have patients with ARC:
Long-lasting diarrhea (over four weeks)
Unintended heavy weight loss
Long lasting fever
Night sweats
Bacterial infections caused by bacteria
Bacterial blood poisoning (sepsis)

Arise from bone in skull base and along spinal cord.
Most common locations -
Cranially at clivus
In sacrum at bottom of spine
Radiation therapy:
Are relatively radioresistant
High doses of radiation required to control.
Hence, high focus radiation like proton therapy and carbon ion therapy are preferred than
conventional radiation methods.
Close proximity to vital structures like brain stem, requires high precision and accuracy for
any planned surgical resection.
Radiation with high accuracy and minimal damage with maximal safety is delivered.
Question 274:
A woman shows symptoms of massive pulmonary thromboembolism.The gross appearance of liver
autopsy is shown. Which of the following statement best characterizes the patient's condition?
A> Metastasis from PE
B> Angiosarcoma
C> Colonic adenocarcinoma with metastasis
D>Locally invaded hepatocellular carcinoma
Answer: Option C
Explanation:
The figure shows appearance of metastatic lesions from a malignant neoplasm with multiple tumor masses
The liver is the most common site of metastases for tumor sites that drain initially via the portal
circulation. Metastatic liver disease is found in 10% to 25% of patients having surgery for primary
colorectal cancer
Surgical resection is the most effective therapy for metastatic colorectal cancer isolated to the liver.
Question 275
Which of the following statement is false about MR vaccination campaign launched by WHO?
A>Children from 9 months to less than 15 vaccinated
B>Congenital rubella syndrome (CRS), responsible for irreversible birth defects
C>India has not yet launched this campaign
D>Will replace routine immunization for measles vaccine
Answer:C
Explanation
One of the world's largest vaccination campaign against measles, a major childhood killer disease,
and congenital rubella syndrome (CRS), responsible for irreversible birth defects.
India, along with ten other WHO South East Asia Region member countries, have resolved to
eliminate measles and control rubella/congenital rubella syndrome (CRS) by 2020
.All children from 9 months to less than 15 years of age will be given a single shot of Measles-
Rubella (MR) vaccination during the campaign
. Following the campaign, MR vaccine will become a part of routine immunization and will replace
measles vaccine, currently given at 9-12 months and 16-24 months of age of child.
For those children who have already received such vaccination, the campaign dose would provide
additional boosting to them.
Question 276.
Which of the following true regarding Hemophilia A
A>Serum levels of factor VIII are decreased.
B>Deficiency of factor IX
C>PT increased
D>FIT decreased
Answer: A
Explanation
Hemophilia is an X linked disorder of coagulation caused by the deficiency in a circulating plasma
protein. Hemophilia A is caused by the deficiency of factor VIII, and hemophilia B is caused by the
deficiency of factor IX.
It is PTT which is affected (increased) and not PT (unaffected).
Factor VIII is involved in the intrinsic pathway which is measured by PTT and not in extrinsic
pathway which is measured as PT.
Bleeding is the common manifestation of hemophilia and the common bleeding manifestations are
hemarthoses, hematomas, mucocutaneous bleeding, intracranial bleeding, hematuria and
pseudotumor.
Question 277
Marked bleeding is seen in which of following conditions?
A>VMA disease
B>Haemophilia A
C>Haemophilia B
D>ALL
Answer: D
Explanation
Bleeding disorders can be inherited or acquired. Inherited disorders are passed down through genetics.
Acquired disorders can develop or spontaneously occur later in life. Some bleeding disorders can result in
severe bleeding following an accident or injury. In other disorders, heavy bleeding can happen suddenly
and for no reason.
There are numerous different bleeding disorders, but the following are the most common ones:
Hemophilia A and B are conditions that occur when there are low levels of clotting factors in your blood. It
causes heavy or unusual bleeding into the joints. Though hemophilia is rare, it can have life-threatening
complications.
Factor II, V, VII, X, or XII deficiencies are bleeding disorders related to blood clotting problems or abnormal
bleeding problems.
von Willebrand's disease is the most common inherited bleeding disorder. It develops when the blood
lacks von Willebrand factor, which helps the blood to clot.
Question 278
Reed sternberg cells are found in
A>Hodgkin's disease
B>Sickle cell anaemia
C> Thalassemia
D>CML
Answer: A
Explanation:
Reed-Sternberg cells
They are usually derived from B lymphocytes, classically considered crippled germinal center B cells.
Seen against a sea of B cells, they give the tissue a moth-eaten appearance.
They are named after Dorothy Reed Mendenhall and Carl Sternberg, who provided the first
definitive microscopic descriptions of Hodgkin's disease.
Reed-Sternberg cells are large and are either multinucleated or have a bibbed nucleus (thus
resembling an "owl's eye" appearance) with prominent eosinophilic inclusion-like nucleoli.
Reed-Sternberg cells are CD30 and CD15 positive, usually negative for CD20 and CD45.
The presence of these cells is necessary in the diagnosis of Hodgkin's lymphoma - the absence of
Reed-Sternberg cells has very high negative predictive value.
They can also be found in reactive lymphadenopathy (such as infectious mononucleosis,
carbamazepine associated lymphadenopathy) and very often in other types of non-Hodgkin
lymphomas.
A special type of Reed-Sternberg cells is the lacunar histiocyte, whose cytoplasm retracts when
fixed in formalin, so the nuclei give the appearance of cells that lie with empty spaces (called
lacunae) between them.
These are characteristic of the nodular sclerosis subtype of Hodgkin's lymphoma
Question 279
A bedridden patient experiences acute chest pain which is worsened by breathing.Which imaging
techniques could be helpful?
A>USG
B>X-ray chest
C>Ventilation perfusion scan
D>CT scan
Answer:
Explanation. Symptoms of pulmonary embolism (PE) are
Sudden-onset dyspnea
Tachypnea
Chest pain of a "pleuritic" nature (worsened by breathing)
Cough
Hemoptysis
More severe cases can include signs such as cyanosis, collapse, and circulatory instability.
On physical examination, a pleural rub may be audible by stethoscope over affected areas of the lung.
Strain on the right ventricle may be detected as a left parasternal heave, a loud pulmonary component of
the second heart sound, raised jugular venous pressure, and more rarely leg swelling.
The gold standard for diagnosing pulmonary embolism (PE) is pulmonary angiography. Pulmonary
angiography is used less often due to wider acceptance of CT scans, which are non-invasive.
Question 280:
Chordoma arises from:
A> Pharyngeal bursa
B> Notochord
C> Rathke's pouch
D>Luschka's bursa
Answer: Option - B
Explanation: Chordoma is a rare slow-growing neoplasm thought to arise from cellular remnants of the
notochord.
Chordomas can arise from bone in the skull base and anywhere along the spine. The two most common
locations are cranially at the clivus and in the sacrum at the bottom of the spine.
There are three histological variants of chordoma: classical (or "conventional"), chondroid and
dedifferentiated.

Question 282:
Which metal results in "Saturnine gout" formation?
A> Cadmium
B> Lead
C> Beryllium
D> Mercury
Answer: Option - B - Lead
Explanation:
One manifestation of chronic lead toxicity is the rheumatologic entity known as saturnine gout.
Illicitly distilled beverages may inadvertently contain harmful toxins, like metallic lead.
Lead has been known to play a role in purine metabolism & renal insufficiency
Question 283:
Which drug decreases the bone resorption in osteoporosis?
A>Teriparatide
B> Risedronate
C> Cortisone
D> Cimetidine
Answer: Option B - Risedronate
Explanation: Risedronate bisphosphonates inhibits bone resorption by actions on osteoclast precursors in
osteoporosis patients
Risedronate:
Aminobisphosphonate
Indications:
Prevention & treatment of osteoporosis
Mechanism of action:
Inhibits bone resorption by action on osteoclasts
Reduce bone remodelling
More potent in blocking the bone dissolution process.
Teriparatide, an PTH analog, recombinant human PTH is also used, yet in severe cases of
osteoporosis, improving the skeletal microarchitecture
Question 284
Phenylketonuria is due to deficiency of:
A> Phenylalanine
B>Phenylalanine hydroxylase ( PAH)
C> Phenylene
D> All of these
Answer B
Explanation: A birth defect that causes an amino acid called phenylalanine to build up in the body.
PKU is an autosomal recessive metabolic genetic disorder.
PKU is characterized by homozygous or compound heterozygousmutations in the gene for the hepatic
enzyme phenylalanine hydroxylase (PAH), rendering it nonfunctional.
This enzyme is necessary to metabolize the amino acid phenylalanine (Phe) to the amino acid tyrosine
(Tyr). When PAH activity is reduced, phenylalanine accumulates and is converted into phenylpyruvate (also
known as phenylketone), which can be detected in the urine.
The PAH gene is located on chromosome 12 in the bands 12q22-q24.1. More than 400 disease-causing
mutations have been found in the PAH gene.
Question 285
WHICH IS NOT CORRECT:
A> MRI needed to access haemorrhage

D> all of the above
Answer- C
Explanation - Treatment of hematoma depends on the location, symptoms, and the clinical situation. Some
may require no treatment at all while others may be deemed a medical emergency.
Simple therapies at home may be utilized in treating superficial (under the skin) hematomas. Most injuries
and bruises can be treated with resting, icing, compression, and elevating the area. This is remembered by
the acronym RICE.
These measures usually help to reduce inflammation and diminish its symptoms.
Rest
Ice (Apply the ice or cold pack for 20 minutes at a time, 4 to 8 times a day.)
Compress (Compression can be achieved by using elastic bandages.)
Elevate (Elevation of the injured area above the level of the heart is recommended.)
Medical treatment for a hematoma
For certain small and symptom-free hematomas no medical treatment may be necessary. On the other
hand, symptomatic hematomas or those located in certain locations sometimes require medical or surgical
treatment.
Even though no specific mediation is available for the treatment of hematomas, management of any
related symptoms can be achieved by medications. For example, pain from a hematoma can be treated
with pain medications such as acetaminophen (Tylenol).
Surgical drainage is a common method of treatment for certain hematomas.

D. RL INFUSION 240 ml in the first hour followed by 360 ml in the next 5 hours
Ans. B.RL INFUSION 180 ml in the first hour followed by 420 ml in the next 5 hours
Explanation:
Severe dehydration constitutes a medical emergency requiring immediate resuscitation with
intravenous fluids.
Intravenous access should be obtained, and patients should be administered a bolus of 20-30
mL/kg lactated Ringer's (LR) or normal saline (NS).
If pulse, perfusion, and/or mental status do not improve, a second bolus should be administered.
After this, the patient should be given an infusion of 70 mL/kg LR or NS over 5 hours (children < 12
months) or 2.5 hours (older children).
If no peripheral veins are available, an intraosseous line should be placed. Serum electrolytes,
bicarbonate, urea/creatinine, and glucose levels should be sent.

A. Corneum lucidum
B. Corneum spinosum
C. Spinosum and basale
D. Basale granulosum
Ans.C.Spinosum and basale
Explanation:
The Malpighian layer of the skin is generally defined as both the stratum basale and stratum spinosum as a
unit, although it is occasionally defined as the stratum basale specifically,or the stratum spinosum
specifically. It is named after Marcello Malpighi.
Question 294:
Mechanism of action colchicine in acute gout
A. Uric acid nephrolithiasis.
B. Deficiency of enzyme Xanthine oxidase.
C. Increase in serum urate concentration.
D. Renal disease involving interstitial tissues.
Ans.B.Deficiency of enzyme Xanthine oxidase.
Explanation:
Gout is a hereditary disorder with increase in serum uric acid due to increased production, or
decreased excretion of uric acid and uric salt.

Question 297:
Mobitz type 2 second degree AV block is seen in all except:
A: Hypothyroidism
B: Coronary Artery Disease
C: Sarcoidosis
D: Cushing syndrome
Ans: D. Cushing syndrome
Explanation :
Delay or lack of conduction through the atrioventricular (AV) node and below has multiple causes.
Degenerative changes (eg, fibrosis, calcification, or infiltration) are the most common cause of non-
ischeamic AV block. Idiopathic fibrosis or calcification of the AV conduction system, commonly seen in the
elderly, can cause complete AV block.
Causes of Mobitz type 2 second degree AV block are -
Damage of the conduction system from coronary artery disease, valve surgery, myocardial infarction,
myocarditis, infiltrative cardiomyopathies (sarcoidosis, hemochromatosis), myxedema, Lyme disease,
neuromuscular disease, and AV junction ablation [6]

Question 299:
A 6-year-old boy experienced life threatening shock ,his CT scan showed large amount of ascites, bowel
wall thickening and poor or absent enhancement of the strangulated bowel segment, showing
gangrenous bowel on surgical exploration.
True about anastomosis is-
A:Should be done by continuous layers as it takes less time
B: Should be Done with catgut
C: Should be Done by single layer seromuscular lembert sutures
D: Should be Done by Single layer taking submucosa
Ans C
Explanation:
Diagnosis is of congenital IH with strangulated small bowel with gangrenous small bowel
Transmesenteric hernia was the most common type in older children as well as in neonates .
IH results from incomplete closure of surgically created mesenteric defects, and usually acquired
resulting from previous abdominal surgery especially Roux-en-Y anastomosis
Anastomosis should be done by single layer seromuscular lembert sutures
The Lambert suture generally is used in abdominal surgery. It is an inverting suture, that can be
either continuous or interrupted, used to join two segments of an intestine without entering the
lumen (the inner channel through which stomach contents flow).

Ans. A. Amiodarone
Explanation:
V-Fib or VF is the most common rhythm that occurs immediately after cardiac arrest. In this rhythm, the
heart beats with rapid, erratic electrical impulses.
Treatment:
Shock / Defibrillation: every 2 minutes in a single one shock, successive, shockable increments
200 joules - Followed by immediate CPR for 2 minutes / give and circulate a drug(s)
300 joules - Followed by immediate CPR for 2 minutes / give and circulate a drug(s)
360 joules - Followed by immediate CPR for 2 minutes / give and circulate a drug(s)
Drugs :
Give Epinephrine 1mg of a 1:10,000 solu,on every 3 to 5 minutes [No Limit]
Give either:
Amiodarone [if not contraindicated, can be given 2x]: 300mg first dose / 150mg second
dose at 3 to 5 minutes increments.
