MULTIPLE CHOICE
1. Which information explains how beta -adrenergic blocking agents reduce
myocardial ox ygen demand?
a. Inhibit the stimulation of norepinephrine and epinephrine.
b. Increase the production of dopamine and acet ylcholine.
c. Delay the destruction of acet ylcholinesterase and cholinesterase.
d. Enhance the sensitivit y of alpha receptors and beta receptors.
ANS: A
Beta-adrenergic blocking agents prevent the stimulation of epinephrine and
norepinephrine, which normall y increase heart rate. Dopamine and
acet ylcholine are not beta -adrenergic neurotransmitters. Beta blockers do not
delay the destruction of these enz ymes. Beta blockers do not enhance the
sensitivit y of alpha adrenergic and beta receptor sites.

2. Which instruction will the nurse provide when teaching a patient about
nitrogl ycerin prior to discharge to home?
, a. “Report any headaches following self -administration to your
healthcare provider. ”
b. “Carry the medication in a pock et directly next to the body. ”
c. “Carry the medication with you at all times. ”
d. “Store nitrogl ycerin in a clear glass container with a tight lid. ”
ANS: C
Nonhospitalized patients should carry nitrogl ycerin at all times. Headache is
an expected adverse effec t. Heat causes the medication to deteriorate, so
being carried next to the body would cause it to become ineffective. Tablets
are degraded by sunlight.

3. Which risk is minimized when the smallest dose of nitrogl ycerin is used to
provide satisfactory results?
a. Allergy
b. Dependence
c. Tolerance
d. Nausea
ANS: C
Tolerance to nitrates can develop rapidl y, particularl y if large doses are
administered frequentl y. Allergy to nitrates is highl y unlikel y. Increasing
dosages and frequency of nitrate use is more likel y to reflect dete rioration of
cardiac function than dependence on the medication. Nausea is not a common
adverse effect of nitrate treatment.

4. Which t ype of angina is precipitated by physical exertion and is relieved by
rest?
a. Chronic stable
b. Nocturnal
c. Unstable
d. Variant
ANS: A
Chronic stable angina is prec ipitated by physical exertion or stress, lasts onl y
a few minutes, and is relieved by rest or nitrogl ycerin. Nocturnal is not a
designated classification. Unstable angina is unpredictable. Variant angina
occurs at rest.

5. Which rationale is behind administering calcium channel blockers to
patients with angina?
a. They decrease heart rate.
b. They dilate blood vessels.
c. They increase cardiac contractilit y.
d. They promote fluid excretion.
