Answer to Question 1

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

Answer to Question 2

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