Answer to Question 1

ANS: C
The autopsy would reveal platelet aggregation within an atherosclerotic coronary artery. The cause of death is most likely occlusion of the coronary artery, not emboli from the aorta, de-creased filling time, or dysplasia in the artery.

Answer to Question 2

ANS: B
Unstable angina is an indication of impending MI. Unstable angina could be caused by moderate atherosclerosis, altered electrical conduction, or a decrease in myocardial oxygen, but it is an in-dication of impending MI.
