Question 1 of 9
A child was treated with baking soda for an upset stomach. Most likely complication is:
Correct Answer: B
Rationale: Baking soda (sodium bicarbonate) overdose causes hypernatremia from excess sodium, potentially with alkalosis (UpToDate). A, C-E are less likely.
Question 2 of 9
What is the most appropriate therapy to maximise his urinary excretion of aspirin?
Correct Answer: D
Rationale: Aspirin (acetylsalicylic acid) overdose requires enhanced excretion. Urinary alkalinisation (Choice D) with bicarbonate increases urine pH, ionizing salicylate (weak acid), trapping it in urine for excretion, and is the standard approach. Allopurinol (Choice A) treats gout, not relevant. Forced diuresis with furosemide (Choice B) increases volume but not pH. Hyperhydration (Choice C) dilutes but doesn’t optimize excretion. Alkalinisation is most effective.
Question 3 of 9
A 4-year-old girl presents with fever and a pruritic rash starting on the trunk. Exam shows vesicles and crusts. Most likely diagnosis is:
Correct Answer: B
Rationale: Chickenpox presents with fever and a pruritic vesicular rash, per CDC. A, C-E have different rash patterns.
Question 4 of 9
Doctor orders: levothyroxine 0.2 mg PO daily. Available is levothyroxine 200 mcg/tab. How many tablets will you give?
Correct Answer: A
Rationale: To determine the number of tablets, convert the ordered dose to the same units as the available dose. Ordered: 0.2 mg = 0.2 × 1000 = 200 mcg. Available: 200 mcg per tablet. Divide the ordered dose by the available dose per tablet: 200 mcg ÷ 200 mcg/tab = 1 tablet. Thus, you give 1 tablet.
Question 5 of 9
The diagnosis of an umbilical arterial thrombus in a preterm newborn is usually made by:
Correct Answer: D
Rationale: Aortic ultrasonography directly visualizes umbilical arterial thrombus in preterms, being non-invasive and specific (AAP). Other options (A-C, E) are less diagnostic.
