When teaching a client about propranolol hydrochloride, the nurse should base the information on the knowledge that propranolol:

  • A. Blocks beta-adrenergic stimulation and thus causes decreased heart rate, myocardial contractility, and conduction.
  • B. Increases norepinephrine secretion and thus decreases blood pressure and heart rate.
  • C. Is a diuretic that reduces peripheral vascular resistance and lowers blood pressure.
  • D. Is an angiotensin-converting enzyme inhibitor that reduces blood pressure by blocking the conversion of angiotensin I to angiotensin II.
Correct Answer: A

Rationale: Propranolol, a beta-blocker, blocks beta-adrenergic receptors, reducing heart rate, contractility, and conduction, lowering blood pressure.
