Answer to Question 1

ANS: A
Systolic murmurs are produced by an incompetent atrioventricular (AV) valve or a stenotic semi-lunar valve. An incompetent AV valve allows a backflow of blood into the atrium, usually pro-ducing a high-pitched whooshing noise simultaneously with S1.

Answer to Question 2

ANS: D
Pulmonary hypertension produces an increased intensity of S2. This sound is referred to as a loud P2 and is a result of more forceful closure of the pulmonic valve.
