Below is a preview of sample questions included in this mock test. Launch the live simulator to attempt the complete test.
Question 1
A 5-week-old boy has progressive projectile non-bilious vomiting and remains hungry after vomiting. Which acid-base abnormality is most likely?
A. Metabolic acidosis with hyperkalaemia
B. Hypochloraemic hypokalaemic metabolic alkalosis
C. Respiratory alkalosis
D. Normal-anion-gap metabolic acidosis
Textbook Explanation Highlight:
Hypertrophic pyloric stenosis causes loss of gastric hydrochloric acid and volume, producing hypochloraemic metabolic alkalosis with potassium depletion. Fluid and electrolyte correction precedes pyloromyotomy.
Question 2
A 9-month-old infant has episodic colicky pain, draws the legs up, vomits and passes red currant-jelly stool. In the absence of perforation or peritonitis, the preferred initial treatment is
A. Immediate laparotomy in every case
B. Pneumatic or hydrostatic enema reduction
C. Oral antibiotics
D. Appendicectomy
Textbook Explanation Highlight:
The presentation is ileocolic intussusception. Image-guided air or contrast enema is both diagnostic and therapeutic when there is no perforation, shock or peritonitis; surgery is used if reduction fails or complications exist.
Question 3
A newborn has abdominal distension, bilious vomiting and delayed passage of meconium. Rectal examination produces explosive stool. The definitive diagnostic test is
A. Barium meal
B. Rectal suction biopsy
C. Serum chloride estimation
D. Colonoscopy alone
Textbook Explanation Highlight:
Hirschsprung disease results from distal aganglionosis. Rectal suction biopsy demonstrating absence of ganglion cells, often with hypertrophic nerve trunks, confirms the diagnosis.
Question 4
A newborn has excessive salivation, coughing and cyanosis during the first feed, and a nasogastric tube coils in the upper pouch. The commonest anatomical type is
A. Pure oesophageal atresia
B. Oesophageal atresia with distal tracheo-oesophageal fistula
C. H-type fistula without atresia
D. Oesophageal atresia with proximal fistula only
Textbook Explanation Highlight:
The commonest configuration is proximal oesophageal atresia with a distal tracheo-oesophageal fistula. Initial care includes stopping feeds, continuous upper-pouch suction and preventing aspiration before repair.
Question 5
A neonate has severe respiratory distress, a scaphoid abdomen and bowel sounds in the left chest. What should be done before definitive repair?
A. Immediate bag-mask ventilation
B. Endotracheal intubation and gastric decompression
C. Immediate oral feeding
D. Needle decompression of both pleural spaces
Textbook Explanation Highlight:
Congenital diaphragmatic hernia causes pulmonary hypoplasia and bowel compression of the lung. Bag-mask ventilation distends intrathoracic bowel; intubation, gentle ventilation and nasogastric decompression are required before delayed repair after st...
