The health-care provider prescribes an ACE inhibitor for the client diagnosed with essential hypertension. Which statement is the most appropriate rationale for administering this medication?
ACE inhibitors prevent the beta-receptor stimulation in the heart.
This medication blocks the alpha receptors in the vascular smooth muscle.
ACE inhibitors prevent vasoconstriction and sodium and water retention.
ACE inhibitors decrease blood pressure by relaxing vascular smooth muscle.
Beta-adrenergic blocking agents, not ACE inhibitors, prevent the beta-receptor stimulation in the heart, which decreases heart rate and cardiac output.
Alpha-adrenergic blockers, not ACE inhibitors, block alpha receptors in the vascular smooth muscle, which decreases vasomotor tone and vasoconstriction.
Angiotensin-converting enzyme (ACE) inhibitors prevent the conversion of angio tensin I to angiotensin II, and this, in turn, prevents vasoconstriction and sodium and water retention.
Vasodilators, not ACE inhibitors, reduce blood pressure by relaxing vascular smooth muscle, especially in the arterioles.
