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 c. Alpha receptors
b. Gamma 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 c. Alpha receptor
b. Beta 2 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
5. What immunoglobulin antibody sensitizes the mast cell?
a. Leukotrienes c. Histamine
b. IgE d. Prostaglandins
ANS: B
The IgE (reagin) antibodies sensitize the mast cell. Repeated exposure to the antigen causes the
degranulation of the mast cell.
PTS: 1
6. Which of the following is caused by histamine release from the mast cells?
I. Bronchodilation
II. Increased bronchial gland secretion
III. Increased amount of mucus present in the airways
a. I and II only c. III only
b. II and III only d. I, II, III
ANS: B
Histamine is also a potent bronchoconstrictor. In addition to its bronchoconstrictive activity, histamine
II) increases bronchial gland secretion, causing III) an increase in the amount of mucus present
in the airways. Histamine may also have an effect on vascular permeability similar to the effect ofSRS-A.
PTS: 1
7. A sympathomimetic drug would cause
a. bronchodilation. c. Histamine release.
b. bronchoconstriction. d. Vagus nerve stimulation.
ANS: A
A sympathomimetic drug would cause bronchodilation. Sympathomimetic agents are the drugs most
commonly used to reverse bronchospasm.
PTS: 1
8. Stimulation of the sympathetic nervous system causes
a. vascular permeability. c. bronchodilation.
b. decreased blood pressure. d. bronchoconstriction.
ANS: C
Sympathetic nervous system stimulation causes bronchodilation.
PTS: 1
