Answer to Question 1

ANS: A
The aortic valve closes creating S2. After the aortic valve closes, in aortic regurgitation, some blood flows back into the left ventricle. S1 through S2 is the systolic time frame. S2 through S1 is the diastolic time frame. The sound of a leaky aortic valve would be heard after the aortic valve closes (S2) during early diastole.

Answer to Question 2

ANS: C
Mitral stenosis results from thickening and stiffening of the mitral valve, usually secondary to rheumatic fever. The murmur is generally grade I to IV and low pitched; therefore, it is heard better with the bell at the apex in the left lateral recumbent position. The first heart sound (S1) is loud, followed by S2 and a loud opening snap that precedes the murmur.
