The nurse is caring for a patient on lisinopril (Zestril). The patient asks how this medication affects blood pressure. Which response best explains the medication's effects?
a. "This medication blocks epinephrine and lowers the heart rate, which impacts blood pressure."
b. "This medication stimulates the release of sodium and water to be excreted."
c. "This medication lowers blood pressure by blocking an enzyme that causes blood vessels to constrict."
d. "This medication decreases cardiac out-put."
C
Angiotensin-converting-enzyme (ACE) inhibitors are antihypertensive medications, or medica-tions that lower blood pressure. ACE-inhibitors block angiotensin I from converting to angioten-sin II and cause vasoconstriction. This action prevents blood pressure from increasing.
