A neonate presents with persistent hypoglycemia despite adequate enteral feeding. Which condition should be suspected?

Correct Answer: B

Rationale: Hyperinsulinism is a common cause of persistent neonatal hypoglycemia due to excessive insulin production. It requires medical management with dextrose infusions or medications like diazoxide to prevent neurodevelopmental impairment.

Correct Answer: B

Rationale: Tumor lysis syndrome leads to hyperkalemia due to the rapid breakdown of cancer cells, releasing intracellular potassium into the bloodstream.

Correct Answer: C

Rationale: Hypoventilation, decreased breath-holding ability, ectopic beats, and supraventricular tachycardia (SVT) are part of the physiological response to cold water immersion, but hypertension is not typically a component of cold water shock.

Correct Answer: C

Rationale: Early onset is typically associated with a worse prognosis.

Correct Answer: D
