SECTION 1: CARDIOVASCULAR SYSTEM (Questions 1–30)
1. A 68yearold male is evaluated for suddenonset rightsided weakness and expressive aphasia. A
noncontrast head CT scan rules out acute intracranial hemorrhage. What is the critical therapeutic
window for the administration of intravenous recombinant tissue plasminogen activator (rtPA)?
A. Within 1 hour of symptom onset
B. Within 3.5 to 4.5 hours of symptom onset
C. Within 12 hours of symptom onset
D. Within 24 hours of symptom onset
Answer: B
Explanation: For acute ischemic stroke, intravenous thrombolytic therapy with rtPA (alteplase) is most
beneficial when administered within a strict time window of 3.5 to 4.5 hours from symptom onset in
carefully selected eligible patients. Administering rtPA outside this window significantly increases the
risk of fatal intracranial hemorrhage.
2. A 72yearold male with a history of hypertension presents with the acute onset of a tearing chest pain
that radiates to the back. His blood pressure is 180/95 mmHg in the right arm and 130/80 mmHg in the
left arm. What is the most likely diagnosis?
A. Acute Myocardial Infarction
B. Aortic Dissection
C. Pulmonary Embolism
D. Pericarditis
,Answer: B
Explanation: This presentation is classic for an aortic dissection. Key features include the sudden onset
of severe, tearing chest pain that radiates to the back, often accompanied by a significant blood
pressure differential between the arms (≥20 mmHg difference). This is a hypertensive emergency that
requires immediate CT angiography for diagnosis.
3. A 68yearold male presents with exertional chest pressure. On cardiac auscultation, you hear a harsh
crescendodecrescendo systolic murmur at the right upper sternal border that radiates to the carotid
arteries. What is the most likely diagnosis?
A. Mitral regurgitation
B. Aortic stenosis
C. Mitral stenosis
D. Aortic regurgitation
Answer: B
Explanation: A harsh crescendodecrescendo systolic murmur at the right upper sternal border radiating
to the carotids is classic for aortic stenosis. Mitral regurgitation radiates to the axilla, mitral stenosis is a
diastolic rumble at the apex, and aortic regurgitation is a diastolic decrescendo murmur at the left upper
sternal border.
4. During cardiac examination of a 45yearold female, you hear a midsystolic click followed by a late
systolic murmur at the apex. The murmur intensifies with standing and Valsalva. What is the diagnosis?
A. Aortic stenosis
B. Mitral valve prolapse
C. Tricuspid regurgitation
D. Hypertrophic cardiomyopathy
,Answer: B
Explanation: Midsystolic click with late systolic murmur at the apex is pathognomonic for mitral valve
prolapse (MVP). Standing/Valsalva (decreased preload) intensifies the murmur. Hypertrophic
cardiomyopathy also intensifies with standing but produces a harsh systolic murmur without a click.
5. A 72yearold with heart failure has a displaced PMI to the left of the midclavicular line at the 6th
intercostal space. What does this finding indicate?
A. Left ventricular hypertrophy
B. Right ventricular hypertrophy
C. Left atrial enlargement
D. Pericardial effusion
Answer: A
Explanation: A displaced, sustained PMI laterally and inferiorly indicates left ventricular
enlargement/hypertrophy. Right ventricular hypertrophy causes a heave at the left lower sternal border.
Pericardial effusion causes muffled heart sounds and distant PMI.
6. You observe JVP elevation with a prominent Y descent in a patient with constrictive pericarditis.
Which additional finding supports this diagnosis?
A. Pulsus paradoxus >20 mmHg
B. Kussmaul sign (JVP rises with inspiration)
C. Cannon A waves
D. Absent Y descent
Answer: B
Explanation: Kussmaul sign (paradoxical JVP rise with inspiration) is characteristic of constrictive
pericarditis and restrictive cardiomyopathy due to impaired RV filling. Pulsus paradoxus >20 mmHg is
seen in cardiac tamponade. Cannon A waves are seen in complete heart block or ventricular tachycardia.
, 7. A patient with acute decompensated heart failure has an S3 gallop. What is the pathophysiology of
this finding?
A. Atrial contraction against a noncompliant ventricle
B. Sudden deceleration of blood filling a volumeoverloaded ventricle
C. Pericardial inflammation
D. Papillary muscle dysfunction
Answer: B
Explanation: S3 occurs in early diastole due to abrupt cessation of rapid ventricular filling in a dilated,
volumeoverloaded ventricle (heart failure). S4 is caused by atrial contraction against a stiff,
noncompliant ventricle.
8. A patient presents with JVD, hypotension, and muffled heart sounds. These findings are known as
Beck's triad and suggest which condition?
A. Pulmonary embolism
B. Cardiac tamponade
C. Aortic dissection
D. Myocardial infarction
Answer: B
Explanation: Beck's triad (jugular venous distension, hypotension, and muffled heart sounds) is the
classic presentation of cardiac tamponade, a lifethreatening condition requiring immediate
pericardiocentesis.
