Section 1: Cardiac Assessment (Questions 1-20)
Q1. Your patient presents with a blowing systolic murmur rated 3/6
that is heard best over the left chest at the 5th intercostal space,
left midclavicular space, radiating to the left axilla. This likely
represents which cardiac finding?
A) Aortic stenosis
B) Pulmonic stenosis
C) Mitral regurgitation
D) Tricuspid regurgitation
Answer: C
Rationale: Mitral regurgitation produces a blowing, holosystolic murmur best
heard at the apex (5th ICS, left midclavicular line) with radiation to the left
axilla. This is a classic finding. Aortic stenosis would radiate to the carotids,
and tricuspid regurgitation is best heard at the lower left sternal border .
Q2. While working in a fast-track clinic in an emergency
department, your patient complains of shortness of breath with
activity and near syncope with changing position from seated to
standing. You examine them and notice a harsh systolic murmur
heard best at the right sternal border at the 2nd intercostal space
rated 3/6, which has a bruit radiating to the right carotid artery.
Which examination is most appropriate to order next to evaluate
this murmur?
A) Chest X-ray
B) Transthoracic echocardiogram
