A client with primary hypertension is prescribed terazosin (Hytrin)to treat this condition. What is the mechanism of action of this drug?
A)Prevents conversion of angiotensin I to angiotensin II
B)Prevents beta-receptor stimulation in the heart
C)Inhibits the flow of calcium ions across the cell membrane of vascular tissue and cardiac cells
D)Blocks alpha-receptors in the vascular smooth muscle

Question

Quizplus · Accepted Answer

A)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.
