Answer to Question 1

ANS: A
Right ventricular hypertrophy, a common manifestation of chronic lung disease, often produces a systolic thrust called a heave that is felt and possibly visualized near the lower left sternal border.

Answer to Question 2

ANS: A
When systole ends, the ventricles relax, and the pulmonic and aortic (semilunar) valves close, creating the second heart sound (S2).
