Answer to Question 1

ANS: C
Normal heart sounds are created by closure of the heart valves.

Answer to Question 2

ANS: B
The PMI may shift either left or right, following deviations in the position of the lower medias-tinum, which may be caused by pneumothorax or lobar collapse. Typically, the PMI shifts toward lobar collapse but away from a tension pneumothorax. The PMI in patients with emphysema and low flat diaphragms may be shifted centrally to the epigastric area.
