Section 1: Cardiovascular Medicine
Q1: A 68-year-old man with hypertension and type 2 diabetes presents with substernal chest pressure
during exertion for two weeks. An exercise stress test reveals 2 mm ST depression in leads V4–V6. What
is the most appropriate next step?
A. Coronary CT angiography
B. Percutaneous coronary intervention
C. Initiate high-intensity statin and aspirin
D. Invasive coronary angiography [CORRECT]
Correct Answer: D
Rationale: In a patient with moderate-to-high pretest probability and a positive stress test showing
significant ST depression (≥2mm), invasive coronary angiography is the gold standard to define anatomy
and guide revascularization. Choice C is insufficient as a standalone next step because the high-risk
stress test findings necessitate anatomical definition to rule out left main or three-vessel disease. Key
takeaway: High-risk stress test features (early positivity, >2mm ST depression, hemodynamic instability)
warrant invasive angiography.
Q2: A 55-year-old woman presents with acute onset dyspnea and palpitations. She has a history of
hypertension. Vital signs: BP 110/70 mmHg, HR 136 bpm, irregularly irregular, RR 22. Lungs are clear.
What is the most appropriate immediate management?
A. IV Diltiazem
B. Synchronized cardioversion
,C. IV Amiodarone
D. IV Metoprolol [CORRECT]
Correct Answer: A
Rationale: The patient is in atrial fibrillation with rapid ventricular response (RVR) but is
hemodynamically stable (no hypotension, chest pain, or altered mental status). Rate control with a non-
dihydropyridine calcium channel blocker (Diltiazem) or beta-blocker is the first-line management. Choice
B is reserved for hemodynamic instability. Choice D (metoprolol) is reasonable but IV Diltiazem is often
more effective for acute rate control in this setting; however, both act as rate control agents. Self-
correction: I marked D as correct in the text but A is the standard first-line for acute rate control in many
protocols if beta blockers are contraindicated or if rapid control is needed. Actually, let's stick to A or D.
Let's make D the distractor for rate control vs rhythm control. Wait, I need to correct the output. D is
correct if we choose beta blocker. Let's use D as the correct answer in the text below. Let's refine the
distractor.
Revised Answer Choice for Output:
A. IV Diltiazem [CORRECT]
Rationale: The patient is hemodynamically stable; therefore, immediate electrical cardioversion is not
indicated. IV Diltiazem is preferred for acute rate control in patients without decompensated heart
failure. Key takeaway: Rate control is the first priority in stable atrial fibrillation with RVR.
Q3: A 72-year-old man with a bicuspid aortic valve presents with exertional dyspnea and syncope. On
exam, there is a harsh late-peaking systolic murmur at the right upper sternal border radiating to the
carotids. The carotid pulse is delayed and diminished (pulsus parvus et tardus). Which of the following is
the most likely diagnosis?
A. Aortic regurgitation
B. Hypertrophic obstructive cardiomyopathy
C. Severe aortic stenosis [CORRECT]
D. Mitral valve prolapse
Correct Answer: C
Rationale: The classic triad of exertional dyspnea, syncope, and angina, combined with a harsh systolic
murmur and pulsus parvus et tardus, is pathognomonic for severe aortic stenosis. Choice A causes a
diastolic decrescendo murmur. Choice B causes a systolic murmur that increases with Valsalva, not the
carotid findings described. Key takeaway: Pulsus parvus et tardus is a specific physical exam finding for
severe aortic stenosis.
,Q4: A 65-year-old man with ischemic cardiomyopathy (LVEF 30%) presents with weight gain and edema.
He is on lisinopril, carvedilol, and furosemide. His labs show K+ 5.8 mEq/L and creatinine 1.8 mg/dL.
What is the best next step in management?
A. Add spironolactone
B. Increase furosemide
C. Switch lisinopril to losartan
D. Hold lisinopril [CORRECT]
Correct Answer: D
Rationale: The patient has significant hyperkalemia (K+ 5.8) and renal insufficiency likely secondary to
RAAS blockade (ACE inhibitor). The immediate priority is to hold the offending agent to prevent life-
threatening arrhythmias. Choice A is contraindicated due to hyperkalemia. Key takeaway: Always assess
renal function and potassium before initiating or continuing ACEi/ARB/MRAs in heart failure.
Q5: EKG Interpretation: A 58-year-old man presents with chest pain. The EKG shows ST elevation in
leads II, III, and aVF with reciprocal ST depression in leads I and aVL. What is the diagnosis?
A. Anterior wall STEMI
B. Inferior wall STEMI [CORRECT]
C. Lateral wall STEMI
D. Pericarditis
Correct Answer: B
Rationale: ST elevations in II, III, and aVF indicate an inferior wall myocardial infarction, typically
involving the right coronary artery. Choice A would show ST elevations in V1-V4. Key takeaway: Inferior
STEMI requires careful assessment for right ventricular involvement (obtain right-sided EKG leads V3R,
V4R).
Q6: A 45-year-old woman presents with "squeezing" chest pain and intermittent dysphagia. A cardiac
workup is negative. Esophageal manometry shows simultaneous, multi-peaked contractions. What is the
most likely diagnosis?
A. Diffuse esophageal spasm [CORRECT]
, B. Achalasia
C. GERD
D. Nutcracker esophagus
Correct Answer: A
Rationale: Diffuse esophageal spasm is characterized by simultaneous, uncoordinated contractions often
described as "corkscrew" esophagus on barium swallow. Choice B shows absent peristalsis and failure of
the lower esophageal sphincter to relax. Key takeaway: Dysphagia plus chest pain with negative cardiac
workup suggests esophageal motility disorder.
Q7: A 70-year-old man presents with 3 days of progressive dyspnea. He has a history of a mechanical
aortic valve replacement. Temperature is 102°F. A new regurgitant murmur is heard. Blood cultures are
pending. What is the most appropriate empiric antibiotic regimen?
A. Vancomycin and Ceftriaxone
B. Vancomycin and Gentamicin
C. Vancomycin, Ceftriaxone, and Gentamicin [CORRECT]
D. Cefazolin
Correct Answer: C
Rationale: This patient has prosthetic valve endocarditis (PVE) until proven otherwise. Empiric therapy
for PVE must cover MRSA (Vancomycin) and gram-negative organisms (Gentamicin), along with
streptococci (Ceftriaxone). Choice A is used for native valve endocarditis. Key takeaway: Prosthetic valve
endocarditis requires aggressive broad-spectrum coverage including aminoglycosides.
Q8: Which of the following is an absolute contraindication to the use of fibrinolytic therapy in a patient
presenting with an acute ischemic stroke?
A. Blood pressure of 175/100 mmHg
B. Blood glucose of 350 mg/dL
C. Prior intracranial hemorrhage [CORRECT]
D. Current warfarin use with INR of 1.6
Correct Answer: C
