Question 1

A 4-year-old with Tetralogy of Fallot has a hypercyanotic (Tet) spell. Which intervention should be performed FIRST?

Accepted Answer

Place in knee-chest position

Answer

The knee-chest position is the first-line intervention as it increases systemic vascular resistance and decreases right-to-left shunting, improving oxygenation.

Question 2

A 10-year-old post-Fontan procedure develops plastic bronchitis. Which finding is MOST characteristic of this complication?

Accepted Answer

Expectoration of branching airway casts

Answer

Plastic bronchitis, a known complication of Fontan circulation, is characterized by expectoration of gelatinous, branching bronchial casts that conform to the airway.

Question 3

A 6-year-old with ARDS is on mechanical ventilation. Lung-protective ventilation strategy includes tidal volume of:

Accepted Answer

6–8 mL/kg ideal body weight

Answer

Lung-protective ventilation for ARDS uses low tidal volumes of 6–8 mL/kg ideal body weight to minimize ventilator-induced lung injury.

Question 4

A 3-year-old presents with sudden onset of high fever, toxic appearance, drooling, and tripod positioning. The PRIORITY intervention is:

Accepted Answer

Prepare for emergent airway management

Answer

Epiglottitis can cause complete airway obstruction; the priority is securing the airway in a controlled environment before any other intervention.

Question 5

Which electrolyte abnormality is MOST likely in a child with prolonged nasogastric suction and metabolic alkalosis?

Accepted Answer

Hypokalemia and hypochloremia

Answer

Nasogastric suction removes gastric acid (HCl), leading to loss of hydrogen, chloride, and potassium, causing metabolic alkalosis with hypokalemia and hypochloremia.
