Cardiology (15 Questions)

findings is:
A. Fever, murmur, and elevated white count.
B. Hypotension, JVD, and muffled heart sounds. ✓
C. Hypertension, bradycardia, and irregular pulse.
D. Chest pain, fever, and pericardial friction rub.
10. When prescribing a statin for secondary prevention in a patient with known CAD, the
target LDL-C reduction is:
A. At least 10%
B. At least 25%
C. At least 50% ✓
D. No specific target, just any reduction
11. A patient presents with acute pulmonary edema. The most appropriate initial vasodilator
in a hypertensive patient is:
A. Lisinopril
,B. Nitroprusside
C. Intravenous Nitroglycerin ✓

A. Acute anterior MI
B. Brugada Syndrome ✓
C. Hypertrophic Cardiomyopathy
D. Long QT Syndrome
13. For a patient with hypertrophic cardiomyopathy (HCM), which medication is
contraindicated?
A. Furosemide
B. Digoxin ✓
C. Metoprolol
D. Verapamil (though beta-blockers are first line, verapamil is sometimes used with caution.
Digoxin is contraindicated due to its inotropic effects).
14. The most common cause of right-sided heart failure is:
A. Mitral valve regurgitation
B. Left-sided heart failure ✓
C. Primary pulmonary hypertension
D. Constrictive pericarditis
15. A "paradoxical" blood pressure (a decrease in systolic BP by more than 10 mmHg during
inspiration) is a sign of:
A. Aortic dissection
B. Cardiac tamponade ✓
C. Pulmonary embolism
D. Abdominal aortic aneurysm
Pulmonology (12 Questions)
16. A patient with COPD and chronic hypoxemia (PaO2 55 mmHg) requires long-term oxygen
therapy. The goal of this therapy is to maintain an O2 saturation of at least:
A. 80%
B. 88%
C. 90% ✓
D. 95%
, 17. The gold standard diagnostic test for confirming a diagnosis of pulmonary embolism is:
A. D-dimer
B. Ventilation-Perfusion (V/Q) Scan
C. CT Pulmonary Angiography (CTPA) ✓
D. Chest X-ray
18. A patient with suspected asthma has a normal spirometry. The best next step to confirm
the diagnosis is:
