MULTIPLE CHOICE

1. Which condition would alert the nurse of the need to use beta-adrenergic blockers cautiously?
A.
Hypertension
B.
Raynaud’s phenomenon
C.
Emphysema
D.
Cardiac dysrhythmias

ANS: C

Feedback
A
Selective beta-1 antagonists are used to treat hypertension.
B
Alpha-adrenergic blocking agents are used to treat patients with Raynaud’s disease.
C
Beta-adrenergic blockers can produce severe bronchoconstriction.
D
Beta-adrenergic blocking agents are indicated for patients with cardiac arrhythmias.

2. A patient with chronic obstructive pulmonary disease (COPD) reports having insomnia and a racing heart after starting terbutaline therapy. Which explanation by the nurse is most accurate?
A.
“The symptoms are usual and indicate that the medication is at a therapeutic level.”
B.
“The symptoms will tend to resolve with continued therapy.”
C.
“The symptoms are unusual and need to be reported to the health care provider immediately.”
D.
“The symptoms are indicative of toxicity.”

ANS: B

Feedback
A
The therapeutic level can only be determined by analyzing a blood sample.
B
Terbutaline, an adrenergic agent effective for bronchodilation, can cause excessive CNS stimulation. Adverse effects such as palpitations, tachycardia, flushed skin, dizziness, and tremors tend to be mild and resolve with continued therapy.
C
These are common symptoms and should only be reported if they persist.
D
Symptoms of toxicity are chest pain, persistent palpitations, and tachycardia.

3. What is the primary response to alpha-1 receptor stimulation?
A.
Bronchodilation
B.
Tachycardia
C.
Vasoconstriction
D.
Uterine relaxation

ANS: C

Feedback
A
Alpha-1 receptor stimulation causes bronchoconstriction.
B
Alpha-1 receptor stimulation does not cause tachycardia.
C
Stimulation of the alpha-1 receptors causes vasoconstriction of all blood vessels throughout the body.
D
Beta-2 receptor stimulation produces relaxation of smooth muscle tissue, such as the uterus.

4. Which category of medications is used for peripheral vascular diseases characterized by excessive vasoconstriction, such as Raynaud’s disease?
A.
Adrenergic agents
B.
Alpha-adrenergic blocking agents
C.
Beta-adrenergic blocking agents
D.
Cholinergic agents

ANS: B

Feedback
A
Adrenergic drugs cause vasoconstriction.
B
Alpha-adrenergic–blocking agents interfere with the stimulation of alpha-1 and alpha-2 receptors. Because the primary action of alpha-receptor stimulation is vasoconstriction, alpha-adrenergic blocking agents are indicated for patients with diseases associated with vasoconstriction.
C
Beta-adrenergic blocking agents are used to treat hypertension and dysrhythmias.
D
Cholinergic drugs are used to treat ocular diseases such as glaucoma, respiratory tract disease, and urinary system diseases.
