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 ReceptorC. Alpha Receptor
b. Beta 2 ReceptorD. 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

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?

b. Ii And Iii Only D. I, Ii, Iii
Ans: B
Histamine Is Also A Potent Bronchoconstrictor. In Addition To Its Bronchoconstrictive Activity, Histamine
