A patient who has been taking an antihypertensive medication for several years is recovering from a myocardial infarction. The prescriber changes the patient's medication to an ACE inhibitor
The patient asks the nurse why a new drug is necessary. What is the nurse's response?
a. "ACE inhibitors can prevent or reverse pathologic changes in the heart's structure."
b. "ACE inhibitors help lower LDL cholesterol and raise HDL cholesterol."
c. "ACE inhibitors increase venous return to the heart, improving cardiac output."
d. "ACE inhibitors regulate electrolytes that affect the cardiac rhythm."
ANS: A
ACE inhibitors have many advantages over other antihypertensive medications, the most important of which is their ability to prevent or reverse pathologic changes in the heart and reduce the risk of cardiac mortality caused by hypertension. They are useful in patients with high low-density lipoprotein (LDL) or low high-density lipoprotein (HDL) cholesterol, but they do not directly affect this comorbidity. They reduce venous return to the heart, thereby reducing right heart size. They do not alter serum electrolyte levels.
