MULTIPLE CHOICE
1. What is the name of the receptor sites that are located in the peripheral vasculature, the heart, bronchial
muscle, and bronchial blood vessels?
a. Beta 2 receptors
b. Gamma receptors
c. Alpha receptors
d.
Beta 1 receptors
ANS: C
Alpha receptors are located in the peripheral vasculature, the heart, bronchial muscle, and bronchial
blood vessels.
PTS: 1
2. Which receptor site results in tachycardia, an increased potential for arrhythmias, and an increased
cardiac output?
a. Beta 1 receptor
b. Beta 2 receptor
c. Alpha receptor
d. Delta receptor
ANS: A
Stimulation of the beta-1 receptors results in tachycardia, an increased potential for arrhythmias, and
an increased cardiac output. In administering drugs to the pulmonary system, stimulation of the beta-1
sites is not desired. However, most respiratory pharmacologic agents have some beta-1 stimulatory
effect.
PTS: 1
3. Stimulation of the beta 2 receptors causes
a. peripheral vasoconstriction and mild bronchoconstriction in the lungs.
b. tachycardia, an increased potential for arrhythmias, and an increased cardiac output.
c. bronchodilation.
d. peripheral vasodilation, bradycardia, and decreased cardiac output.
ANS: C
Stimulation of the beta-2 receptors in the lungs causes bronchodilation.
PTS: 1
4. Acetylcholine stimulates
a. the Vagus nerve.
b. the adrenergic receptors.
c. the sympathetic nervous system.
d. the cholinergic receptors.
ANS: D
Acetylcholine stimulates the cholinergic receptors.
PTS: 1
