SYSTEMS
50 Questions with Detailed Rationales
Question 1
A 55-year-old male presents with chest pain that occurs with exertion
and is relieved by rest. The pain is described as a pressure sensation
in the substernal area radiating to the left arm. Which of the following
is the most likely diagnosis?
A) Unstable angina
B) Stable angina
C) Myocardial infarction
D) Pericarditis
Correct Answer: B) Stable angina
,Rationale: Stable angina is characterized by chest pain that occurs
with exertion or stress and is relieved by rest or nitroglycerin. The pain
is typically substernal, pressure-like, and may radiate to the left arm,
jaw, or back. Unstable angina (A) occurs at rest or with minimal
exertion and is a medical emergency. Myocardial infarction (C)
presents with prolonged chest pain not relieved by rest and is
associated with elevated cardiac biomarkers. Pericarditis (D) pain is
typically sharp, pleuritic, and relieved by sitting forward.
Question 2
A 68-year-old female with a history of hypertension and diabetes
presents with progressive dyspnea on exertion and orthopnea.
Physical examination reveals an S3 gallop, jugular venous distension,
and bilateral crackles. Echocardiogram shows an ejection fraction of
25%. Which medication class has been shown to provide the greatest
mortality benefit in this patient population?
A) Calcium channel blockers
B) Beta-blockers
C) Digoxin
D) Hydralazine and isosorbide dinitrate
Correct Answer: B) Beta-blockers
Rationale: Beta-blockers (carvedilol, metoprolol succinate, bisoprolol)
have demonstrated significant mortality reduction in patients with
heart failure with reduced ejection fraction (HFrEF). The MERIT-HF trial
showed a 34% reduction in mortality with metoprolol succinate. While
calcium channel blockers are contraindicated in HFrEF, digoxin
reduces hospitalizations but not mortality, and hydralazine/isosorbide
,dinitrate is specifically beneficial in African American patients but not
first-line for all.
Question 3
A 62-year-old male with a 40-pack-year smoking history presents with
progressive dyspnea, chronic cough, and wheezing. Pulmonary
function tests show an FEV1/FVC ratio of 0.65 and an FEV1 of 55%
predicted. Which of the following is the most appropriate long-term
management?
A) Inhaled corticosteroids alone
B) Long-acting beta-2 agonist (LABA) plus inhaled corticosteroids
C) Theophylline
D) Antibiotics
Correct Answer: B) Long-acting beta-2 agonist (LABA) plus inhaled
corticosteroids
Rationale: This patient has COPD based on the FEV1/FVC ratio <0.70
and a history of smoking. For patients with moderate-to-severe COPD
(GOLD stage 2 or higher), the combination of a LABA and inhaled
corticosteroid has been shown to reduce exacerbations and improve
lung function compared to either alone. LABA alone is also an option,
but the combination is preferred for patients with frequent
exacerbations. Theophylline is a third-line agent. Antibiotics are not
indicated for maintenance therapy.
Question 4
A 45-year-old female presents with acute-onset pleuritic chest pain,
, dyspnea, and tachycardia. She recently traveled on a long international
flight. Her oxygen saturation is 92% on room air. Wells score is 6. What
is the most appropriate diagnostic test?
A) D-dimer
B) CT pulmonary angiography
C) Ventilation-perfusion (V/Q) scan
D) Chest X-ray
Correct Answer: B) CT pulmonary angiography
Rationale: According to the Wells criteria, a score of 6 indicates high
probability for pulmonary embolism. In high-probability patients, CT
pulmonary angiography is the diagnostic test of choice. D-dimer is
appropriate for low to moderate probability. V/Q scan is an alternative
for patients with contraindications to CT. Chest X-ray is insensitive for
PE.
Question 5
A 55-year-old male with COPD presents with increased dyspnea,
purulent sputum, and fever. He is on LABA/ICS. Which of the following
is the most appropriate management for this acute exacerbation?
A) Increase ICS dose
B) Add tiotropium
C) Antibiotics and prednisone
D) Theophylline
Correct Answer: C) Antibiotics and prednisone
