The nurse preparing to administer both a calcium channel blocker and a beta₁-adrenergic blocker to a client with hypertension plans to monitor the client's response based on which understanding of these drugs?

Question

Quizplus · Accepted Answer

Calcium channel blockers prevent calcium influx into vascular smooth muscle, leading to vasodilation and lowering of blood pressure. Beta-adrenergic blockers block sympathetic impulses in sarcolemma membranes, reducing heart rate and contractility. Monitoring the client's response to these medications would involve assessing for changes in blood pressure, heart rate, and potential side effects such as dizziness or fatigue. Option A is incorrect because calcium channel blockers actually prevent calcium influx, rather than promoting it. Option D is incorrect because neither medication promotes urinary excretion of sodium.
