Answer to Question 1

ANS: C
The beta-adrenergic blocking agents block beta receptor stimulation in the heart, which then inhibits cardiac response to sympathetic nerve stimulation. This results in a decrease in heart rate, cardiac output, and blood pressure. Beta blockers do not affect alpha receptors. Beta blockers do not have a diuretic effect. ACE inhibitors are in the class of drugs that affects angiotensin conversion.

Answer to Question 2

ANS: A, B, C
Baseline blood glucose, blood pressure, and heart rate should be determined before initiating niacin therapy. Temperature and oxygen saturation levels are not necessary prior to administering niacin.
