Answer to Question 1

A
Feedback:
Coronary artery disease is characterized by the progressive growth of atheromatous plaques, or atheromas, in the coronary arteries. These plaques, which begin as fatty streaks in the endothelium, eventually injure the endothelial lining of the artery, causing an inflammatory reaction. This inflammatory process triggers the development of characteristic foam cells, containing fats and WBCs that further injure the endothelial lining. Over time, platelets, fibrin, other fats, and remnants collect on the injured vessel lining and cause the atheroma to grow, further narrowing the interior of the blood vessel and limiting blood flow.

Answer to Question 2

C
Feedback:
Bradycardia is a common adverse effect associated with atracurium. The nurse should monitor the patient regularly to avoid serious adverse effects. Increased secretions and hypotension are common with tubocurarine. Option B is a distracter.
