Answer to Question 1

Answer: A

Aging affects the heart and the cardiac conduction system, increasing the incidence of dysrhythmias and conduction defects. Caffeine increases the risk of ectopic beats and rapid heart rates. Antihypertensive medications are not associated with cardiac dysrhythmias. Engaging in routine physical activity will not cause dysrhythmias or conduction defects. The client is a non-smoker and does not ingest alcohol, both of which would contribute to cardiac dysrhythmias.

Answer to Question 2

Answer: D

Terazosin (Hytrin), an alpha-adrenergic blocker, acts by blocking alpha-receptors in the vascular smooth muscle. ACE inhibitor medications prevent conversion of angiotensin I to angiotensin II. Beta-adrenergic blockers prevent beta-receptor stimulation in the heart. Calcium channel blockers inhibit the flow of calcium ions across the cell membrane of vascular tissue and cardiac cells.
