Answer to Question 1

ANS: C
The most common cause of myocardial ischemia is atherosclerosis. Myocardial ischemia is not caused by idiopathic vasospams or venous emboli. Arterial emboli may cause ischemia, but ath-erosclerosis is the major cause of myocardial ischemia.

Answer to Question 2

ANS: C
Foam cells are lipid-laden macrophages that engulf LDL. They are deposited in vessels, not adi-pose cells. Foam cells are not injured neutrophils nor are they mast cells.
