Answer to Question 1

C
Feedback:
Alpha2-receptors are located on nerve membranes and act as modulators of norepinephrine release. When norepinephrine is released from a nerve ending, it crosses the synaptic cleft to react with its specific receptor site. Some of it also flows back to react with the alpha-receptor on the nerve membrane. This causes a reflex decrease in norepinephrine release. In this way, the Alpha2-receptor helps to prevent overstimulation of effector sites.

Answer to Question 2

A
Feedback:
Clopidogrel (Plavix) is indicated for the treatment of patients who are at risk for ischemic events; patients with a history of myocardial infarction, peripheral artery disease, or ischemic stroke; and patients with acute coronary syndrome. Persantine, aspirin, and warfarin would not be indicated for this patient.
