NLE Cardiology MCQs: Practice Questions With Explanations

Sample NLE MCQs from Cardiology — a 118-question subject in HighYield's NLE bank without a dedicated practice post yet — covering heart sounds, murmurs and heart failure.

Cardiology is a 118-question subject in HighYield's NLE (National Licensing Examination) question bank that doesn't yet have a dedicated practice post. Below is a sample set of Cardiology MCQs covering heart sounds, murmurs and heart failure.

Heart Sounds & Murmurs

1. A harsh crescendo-decrescendo systolic murmur, loudest at the right upper sternal border and radiating to the carotids, is classic for:

A) Mitral regurgitation
B) Aortic stenosis ✅
C) Mitral stenosis
D) Tricuspid regurgitation

2. A widely split S2 that does not vary with respiration is characteristic of:

A) Atrial septal defect ✅
B) Aortic stenosis
C) Mitral valve prolapse
D) Physiological splitting

3. A mid-diastolic rumble with an opening snap, best heard at the apex, is classic for:

A) Aortic regurgitation
B) Mitral stenosis ✅
C) Pulmonary stenosis
D) Tricuspid stenosis

Heart Failure

4. Bibasal crackles, raised JVP and bilateral ankle oedema together suggest:

A) Congestive heart failure ✅
B) Isolated right heart failure
C) Pulmonary embolism
D) Constrictive pericarditis

5. In heart failure with reduced ejection fraction, an S3 gallop reflects:

A) Atrial contraction against a stiff ventricle
B) Rapid ventricular filling in a volume-overloaded, dilated ventricle ✅
C) Mitral valve closure
D) Aortic valve opening

ECG & Acute Coronary Syndromes

6. ST-segment elevation in leads II, III and aVF localises an acute myocardial infarction to the:

A) Anterior wall
B) Lateral wall
C) Inferior wall ✅
D) Posterior wall

7. Hypotension, jugular venous distension and muffled heart sounds together form:

A) Cushing's triad
B) Beck's triad ✅
C) Charcot's triad
D) Virchow's triad

8. Peaked T waves progressing to a widened QRS on ECG most classically reflect:

A) Hypokalemia
B) Hyperkalemia ✅
C) Hypercalcemia
D) Hyponatremia
