Answer to Question 1
A
Feedback:
Diltiazem is a calcium channel blocker that is indicated to treat Prinzmetal's angina, chronic angina, effort-associated angina, and hypertension. Research has indicated these agents slow the development of atherosclerosis. Beta-blockers are indicated for long-term management of angina caused by atherosclerosis, but they do not slow the development of plaque deposits on the artery wall. Propranolol is a beta-blocker. Isosorbide dinitrate and amyl nitrate are nitrates and are indicated for relief acute anginal pain, but they are not used to prevent angina and have no effect on the progression of atherosclerosis.
Answer to Question 2
B
Feedback:
Pentazocine must be administered cautiously to patients with known heart disease because the drug may cause cardiac stimulation including arrhythmias, hypertension, and increased myocardial oxygen consumption, which could lead to angina, myocardial infarction, or congestive heart failure. No indication exists that it must be given cautiously to patients with gastrointestinal, urinary, or respiratory diseases.
