Answer to Question 1

ANS: B
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.

Answer to Question 2

ANS: C
The tricuspid valve is best heard over the fourth intercostal space left sternal border. Erb's point is located over the third intercostal space left sternal border. The mitral valve is best heard over the fifth intercostal space in the mid-clavicular line. The aortic valve is best heard over the second intercostal space right sternal border. The pulmonic valve is best heard over the second intercostal space left sternal border.
