Answer to Question 1

ANS: A
Chronic stable angina is precipitated by physical exertion or stress, lasts only a few minutes, and is relieved by rest or nitroglycerin. Nocturnal is not a designated classification. Unstable angina is unpredictable. Variant angina occurs at rest.

Answer to Question 2

ANS: A
Beta-adrenergic blocking agents prevent the stimulation of epinephrine and norepinephrine, which normally increase heart rate. Dopamine and acetylcholine are not beta-adrenergic neurotransmitters. Beta blockers do not delay the destruction of these enzymes. Beta blockers do not enhance the sensitivity of alpha adrenergic and beta receptor sites.
