Answer to Question 1

ANS: B
Beta-adrenergic blocking agents decrease the heart rate and dilate blood vessels to lower blood pressure. Sudden discontinuation of beta-adrenergic blocking agents may result in an exacerbation of angina symptoms. Beta-adrenergic blocking agents may mask symptoms of hypoglycemia. Beta-adrenergic blocking agents may take several days to weeks to show optimal improvement.

Answer to Question 2

ANS: B
Nerve endings that secrete norepinephrine are called adrenergic fibers. These nerve endings liberate acetylcholine. Anticholinergic describes the action of certain medications that inhibit the transmission of parasympathetic nerve impulses and thereby reduce spasms of smooth muscle (e.g., as in the bladder). Muscarinic receptors are those membrane bound acetylcholine receptors that are more sensitive to muscarine than to nicotine.
