The nurse understands that which of the ff. best describes the action of enalapril maleate (Vasotec)?

  • A. It decreases levels of angiotensin II
  • B. It dilates the arterioles and veins
  • C. It adjusts the extracellular volume
  • D. It decreases cardiac output
Correct Answer: A

Rationale: Enalapril maleate (Vasotec) is an angiotensin-converting enzyme (ACE) inhibitor. The main action of ACE inhibitors like enalapril is to decrease the levels of angiotensin II in the body. Angiotensin II is a potent vasoconstrictor that plays a role in regulating blood pressure, stimulating aldosterone secretion, and promoting sodium and water retention. By inhibiting the conversion of angiotensin I to angiotensin II, enalapril reduces vasoconstriction and aldosterone secretion, leading to vasodilation, decreased blood pressure, and ultimately decreased levels of angiotensin II. This mechanism allows for the dilation of arterioles and veins, reduction in cardiac afterload, and ultimately decreases the workload of the heart.
