Sample MCQ 1: Hypertension follow-up
Question: A 56-year-old with newly diagnosed primary hypertension starts a thiazide diuretic. At 1-month follow-up, home BP averages 146/92 mmHg and office BP is 150/94 mmHg. No symptoms, electrolytes normal. What is the next best step? A. Continue same dose and recheck in 6 months B. Add a second first-line antihypertensive from a different class C. Stop thiazide and switch to a beta blocker D. Order renal artery imaging now
Correct answer: B Explanation: If BP remains above goal after about 1 month of therapy, guidelines support either titrating or adding a second first-line agent from a different class rather than waiting months. No red flags here to prompt secondary-cause imaging.
Sample MCQ 2: Antibiotic choice for cystitis
Question: A 24-year-old nonpregnant woman has dysuria and urinary frequency for 2 days. Afebrile, no flank pain, no vaginal symptoms. Urinalysis is positive for leukocyte esterase and nitrites. No drug allergies. Best first-line treatment? A. Nitrofurantoin B. Amoxicillin-clavulanate C. Doxycycline D. Ciprofloxacin
Correct answer: A Explanation: For uncomplicated cystitis, recommended first-line options include nitrofurantoin (when appropriate) due to good efficacy and lower collateral resistance compared with fluoroquinolones. Fluoroquinolones are generally reserved for more complicated cases or when alternatives are unsuitable.
Sample MCQ 3: Diabetic ketoacidosis first step
Question: A 19-year-old with type 1 diabetes arrives with vomiting, abdominal pain, and Kussmaul respirations. Labs show glucose 520 mg/dL, anion gap metabolic acidosis, and positive serum ketones. Potassium is 3.1 mEq/L. What is the next best step? A. Start IV insulin infusion immediately B. Give IV sodium bicarbonate C. Start IV fluids and replace potassium before insulin D. Administer subcutaneous rapid-acting insulin and discharge
Correct answer: C Explanation: In DKA, insulin lowers potassium further; when potassium is low, replace potassium and start fluids before insulin to reduce arrhythmia risk. Bicarbonate is reserved for severe acidosis in select situations, not routine cases.
