Aortic insufficiency/regurgitation murmur is classified as a:
Systolic murmur
Diastolic murmur
Absent murmur
Very faint murmur
The Correct Answer is B
A. Systolic murmur: Systolic murmurs occur during systole and include conditions like aortic stenosis or mitral regurgitation.
B. Diastolic murmur: Aortic insufficiency/regurgitation occurs during diastole when the aortic valve fails to close properly, allowing blood to flow back into the left ventricle.
C. Absent murmur: Aortic insufficiency/regurgitation is not classified as absent; it is detectable with auscultation.
D. Very faint murmur: Although aortic regurgitation murmurs can vary in intensity, the classification pertains to the timing of the murmur, not its loudness.

B. S1: The first heart sound (S1) marks the beginning of systole and corresponds to the closure of the mitral and tricuspid valves.
C. S2: The second heart sound (S2) indicates the end of systole and the beginning of diastole, associated with the closure of the aortic and pulmonic valves.
D. S4: This sound is associated with late diastole, often related to decreased ventricular compliance.
