Correct Answer - A
Ans. is 'A' i.e., Autism
Delayed speech, difficulty in communication and concentration in a 3
year old child suggests the diagnosis of autism.
Autism is characterized by impaired social interaction and
communication, and by restricted and repetitive behavior. These
signs all begin before a child is three years old.
Autism affects information processing in the brain by altering how
nerve cells and their synapses connect and organize
It is one of three recognized disorders in the autism spectrum, the
other two being Asperger syndrome, which lacks delays in cognitive
development and language, and pervasive developmental Disorder-
not otherwise specified (commonly abbreviated as PDD-NOS)

Correct Answer - A
Ans. is 'a' i.e., No treatment
o No treatment is given to children below 6 years of age because of
high spontaneous cure rate. o After 6 years treatment include.
t) Behavioral therapy : This is the treatment of choice.
it) Pharmacological treatment : It is used when non-pharmacological
(behavioral) therapy fails. Desmopressin is the drug of choice. Other
drugs used are impramine and oxybutinin.

Correct Answer - B
Ans. is 'b' i.e., Hypertrophic pyloric stenosis
Hypertophic pyloric stenosis
Most common cause of nonbilious vomiting is Hypertrophic pyloric
stenosis.
Male > female.
Vomiting starts with 3 week of age.
Palpable mass is seen in epigastric region.
Visible peristalsis is seen soon after feeding.
Confirmed by USG abdomen.
Contrast study shows :
. Shoulder sign
. Double tract sign.
Treatment surgery = Ramstedt procedure.

Correct Answer - B

Ans. is 'b' i.e., 45 XO genome Barr body (Sex - chromatin)

o It is a densely staining inactivated condensed 'X' chromosome that

is present in each somatic cells of female.

o It is found in the nucleus.

o It is used as a test of genetic femaleness it is possible to determine the genetic sex of an individual according as to whether there is a chromatin mass present on the inner surface of the nuclear membrane of cells with resting or intermitent nuclei. Remember following fact and the question will seem very easy.

Chromatid body (Barr body or sex chromatin) is derived from one of

the two X-chromosomes which becomes inactivated.

The numer of Barr bodies is thus one less than the number of X- chromosomes.

Note - o Barr body is found in female But -

o Kleinefelter syndrome is male with Barr body.

o Turner syndrome is female without Barr body.

Correct Answer - C
Ans. is 'c' i.e., Streptococcal pneumonia
Most common cause of paediatric pneumonia is respiratory syncytial
virus (RSV). Other viruses causing pneumonia are influenza virus
(2^
d most common virus), adenovirus, rhinovirus, and parainfluenza
virus.
Most common bacterial cause of pediatric pneumonia is
streptococus pneumoniae (pneumococcus). Bacteria causing
atypical pneumonia commonly are mycoplasma and chlamydia

Correct Answer - C
Ans. is 'c' i.e., Type I RTA
Fanconi anemia
Autosomal recessive
Pancytopenia
Hyper pigmentation of trunk, neck, and inlertriginous area.
Growth failure
Fanconi facies (small head, small eyes)
Renal abormality
Proximal RTA (type II RTA)
Renal tubular acidosis 3 types
Distal RTA (type I)
Proximal RTA (type II)
Hyperkalemic RTA (type IV)

Correct Answer - C
Ans. is 'c' i.e., Ringer lactate
Fluid resuscitation in burn injury
Parkland formulaa
a. Initial 24 hours: Ringer's lactated (RL) solution 4 ml/kg/% burn
for adults and 3 ml/kg/% burn for children. RL solution is added for
maintenance for children:
a. 4 ml/kg/hour for children weighing 0-10 kg
b. 40 ml/hour +2 ml/hour for children weighing 10-20 kg
c. 60 ml/hour + 1 ml/kg/hour for children weighing 20 kg or higher
This formula recommends no colloid in the initial 24 hours.
b Next 24 hours: Colloids given as 20-60% of calculated plasma
volume. No crystalloids. Glucose in water is added in amounts
required to maintain a urinary output of 0.5-1 ml/hour in adults
and 1 ml/hour in children.

Correct Answer - B
Ans. is 'b' i.e., 125 mg/dl
o No established definition of neonatal hyperglycemia and upper
safe limit of blood glucose has been determined
o Various researches has suggested
Whole blood glucose > 125 mg/dl
Plasma glucose > 150 mg/dl
