SECTION 1: CARDIOVASCULAR SYSTEM (45 Questions)
Q1: A 68-year-old male with hypertension and diabetes presents with crushing
substernal chest pain radiating to his left arm for 45 minutes. He is diaphoretic. BP
88/52 mmHg, HR 110 bpm, RR 24. ECG shows ST elevations in V1-V4. Which is the next
best step?
A. Immediate sublingual nitroglycerin
B. Emergent PCI within 90 minutes
C. Thrombolytics before transfer
D. Beta-blocker administration
C. Emergent PCI within 90 minutes [CORRECT]
Correct Answer: C
Rationale: This is an anterior STEMI with cardiogenic shock. Current ACC/AHA 2026
guidelines mandate primary PCI within 90 minutes of first medical contact as the
preferred reperfusion strategy. Sublingual nitroglycerin is contraindicated with SBP <90
mmHg. Thrombolytics are second-line when PCI cannot be performed within 120
minutes. Beta-blockers should be deferred in acute heart failure or shock. COMSAE
Verified. Grade A.
Q2: A 55-year-old female has BP consistently 158/96 mmHg on three occasions. She
has no other comorbidities. Lifestyle modifications failed after 3 months. Which
antihypertensive is first-line per JNC-8 and 2026 guidelines?
A. Hydralazine
,B. Chlorthalidone
C. Doxazosin
D. Clonidine
B. Chlorthalidone [CORRECT]
Correct Answer: B
Rationale: For stage 1 hypertension without compelling indications (CKD, diabetes,
heart failure), thiazide-like diuretics (chlorthalidone, indapamide) remain first-line per
2026 ACC/AHA. Hydralazine is reserved for refractory hypertension or pregnancy.
Alpha-blockers and central agonists are not first-line due to side effect profiles.
COMSAE Verified. Grade A.
Q3: A 72-year-old male with HFrEF (EF 30%) on lisinopril and metoprolol presents with
worsening dyspnea and peripheral edema. JVP elevated, S3 gallop present. Which
additional agent reduces mortality in HFrEF?
A. Digoxin
B. Spironolactone
C. Amlodipine
D. Hydralazine-isosorbide (without ARNI indication)
B. Spironolactone [CORRECT]
Correct Answer: B
Rationale: Mineralocorticoid receptor antagonists (spironolactone, eplerenone) reduce
mortality in NYHA Class II-IV HFrEF with EF ≤35% per EMPEROR-Reduced and RALES
trials. Digoxin improves symptoms but not mortality. Amlodipine has neutral mortality
effects. Hydralazine-isosorbide is for African Americans or ACE-I intolerance, but ARNI
(sacubitril/valsartan) is preferred first. COMSAE Verified. Grade A.
Q4: A 45-year-old male collapses during a marathon. Bystanders find him pulseless.
AED reveals ventricular fibrillation. After one shock, rhythm persists. What is the next
intervention?
A. Administer amiodarone 300 mg IV push
B. Immediate second shock
,C. Epinephrine 1 mg IV push
D. Atropine 1 mg IV
A. Administer amiodarone 300 mg IV push [CORRECT]
Correct Answer: A
Rationale: Per 2026 ACLS guidelines, after initial defibrillation for VF/pulseless VT, if
rhythm persists, give epinephrine 1 mg every 3-5 minutes AND amiodarone 300 mg IV
push for refractory VF/VT. However, the first medication after failed shock is
epinephrine, but amiodarone is specifically indicated for shock-refractory VF. In
standard ACLS algorithm: shock → CPR → epinephrine → shock → amiodarone. Given
the question structure, amiodarone is the antiarrhythmic of choice for refractory VF.
COMSAE Verified. Grade A.
Q5: A 60-year-old male with atrial fibrillation (CHADS₂-VASc 4) is started on
anticoagulation. He has moderate CKD (CrCl 35 mL/min). Which agent is preferred?
A. Rivaroxaban 20 mg daily
B. Apixaban 5 mg BID
C. Dabigatran 150 mg BID
D. Warfarin (INR 2-3)
B. Apixaban 5 mg BID [CORRECT]
Correct Answer: B
Rationale: Apixaban is preferred in moderate CKD (CrCl 25-50 mL/min) as it has the
best safety profile and requires no dose adjustment until CrCl <25 mL/min. Rivaroxaban
requires dose reduction at CrCl ≤50. Dabigatran is contraindicated/avoided at CrCl <30.
Warfarin is acceptable but DOACs are preferred for non-valvular AF per 2026 guidelines
unless mechanical valve or moderate-severe mitral stenosis. COMSAE Verified. Grade A.
Q6: A 50-year-old male with sudden tearing chest pain radiating to his back. BP 190/110
mmHg, pulse deficit between arms. CXR shows widened mediastinum. What is the
definitive diagnosis?
A. Acute coronary syndrome
, B. Aortic dissection
C. Pulmonary embolism
D. Pericarditis
B. Aortic dissection [CORRECT]
Correct Answer: B
Rationale: Tearing chest pain with pulse deficit, BP differential between arms, and
widened mediastinum on CXR are classic for aortic dissection (Stanford A or B).
Immediate CTA chest/abdomen/pelvis is diagnostic. ACS presents with ischemic ECG
changes. PE causes dyspnea, tachypnea, and right heart strain. Pericitis causes diffuse
ST elevation and friction rub. COMSAE Verified. Grade A.
Q7: A 35-year-old female with SLE presents with dyspnea, orthopnea, and pericardial
friction rub. ECG shows diffuse ST elevation and PR depression. Echo shows small
pericardial effusion. What is the management?
A. Immediate pericardiocentesis
B. NSAIDs and colchicine
C. Systemic corticosteroids alone
D. Aspirin and heparin
B. NSAIDs and colchicine [CORRECT]
Correct Answer: B
Rationale: This is acute pericarditis with small effusion. First-line therapy is NSAIDs
(ibuprofen/indomethacin) plus colchicine to reduce recurrence per 2026 ESC guidelines.
Pericardiocentesis is indicated for tamponade ( Beck's triad, pulsus paradoxus >20
mmHg) or large effusions. Steroids are reserved for refractory cases or connective
tissue disease flare. Aspirin + heparin could increase bleeding into pericardial space.
COMSAE Verified. Grade A.
Q8: A 40-year-old male with Marfan syndrome presents with acute chest pain. CT
angiography shows ascending aortic aneurysm 5.5 cm with intimal flap. What is the
immediate management?
A. IV beta-blockade and emergent surgery
