Cardiac Question #10


The nurse is caring for a client with heart failure who is receiving a prescribed angiotensin-converting enzyme inhibitor (ACEI). The patient is asking how the drug works for heart failure. What will the nurse include in teaching the client about this medication? (Select all that apply.)


  1. The ACEI reduces fluid volume
    • Rationale:
  2. The ACEI relaxes blood vessels and lowers blood pressure
    • Rationale:
  3. The ACEI reduces workload on the heart
    • Rationale:
  4. The ACEI decreases pulmonary venous pressure.
    • Rationale:



ACEIs are considered the first-choice drug over angiotensin receptor blockers (ARBs). ACEIs block the action of an enzyme that causes narrowing of the heart vessels, and as a result, the vessels relax and widen. As a result, ACEIs have a vasodilation effect, which lowers blood pressure and reduces workload on the heart. They also offer additional benefit by preventing remodeling, which is an effect that leads to progressive cardiac deterioration. ACEIs do not reduce fluid volume or decrease pulmonary venous pressure; however, diuretics reduce fluid volume and decrease pulmonary venous pressure. Some ACEIs are combined with diuretic therapy. The question is specific for just ACEIs and not ACEIs/Diuretic combinations.
