Question 1

A 58-year-old man with type 2 diabetes presents with a painless foot ulcer. ABI is 0.6. Which is the most appropriate next step?

Accepted Answer

Refer for vascular surgery evaluation

Answer

An ABI of 0.6 indicates significant peripheral arterial disease, requiring vascular surgery evaluation before wound healing can proceed.

Question 2

A 72-year-old woman on warfarin for atrial fibrillation is started on fluconazole. What is the expected effect?

Accepted Answer

Increased INR due to CYP2C9 inhibition

Answer

Fluconazole inhibits CYP2C9, which metabolizes warfarin's S-enantiomer, leading to elevated INR and bleeding risk.

Question 3

A 45-year-old woman presents with episodic hypertension, headache, diaphoresis, and palpitations. Which initial test is most appropriate?

Accepted Answer

24-hour urine catecholamines and metanephrines

Answer

The classic triad of headache, diaphoresis, and palpitations with episodic hypertension suggests pheochromocytoma, best screened with 24-hour urine metanephrines.

Question 4

A 3-year-old child is brought in with a barking cough, inspiratory stridor, and low-grade fever. Which pathogen is most likely responsible?

Croup (laryngotracheobronchitis) is most commonly caused by parainfluenza virus type 1 and presents with the characteristic barking cough and stridor.

Question 5

Which finding on ECG is most consistent with hyperkalemia?
