HTN Flashcards
Action of ACE inhibitor
Inhibits renin-angiotensin-aldosterone mechanism by blocking conversion of angiotensin I to angiotensin II, which prevents peripheral vasoconstriction and reduces blood volume. Also used to treat HTN

always end with -sartan
Action of ARBs
Blocks vasoconstriction and aldosterone-secretion effects of angiotensin II at receptor site.Lowers BPDecreases risk for heart failure.
Nursing consideration for ARBs
Monitor BPMonitor for hypotension, especially clients who take diureticsAvoid salt substitutes because of Potassium

Carvedilol (Coreg)
Memory aid for Beta Blockers
Always end with -olol or -lol
Action of Beta blockers
Blocks beta1 adrenergic receptor (blocks beta2 in lungs if dose is high enough) found in cardiac muscle.Decreases HTN
Name a Vasodilator
Hydralazine (Apresoline)
Action of a vasodilator
Acts directly on arterial smooth muscle to cause vasodilation.Decrease HTN
Name Diuretic
Furosemide (Lasix)
Action of a diuretic
Increases renal excretion of water and other electrolytes
Decreases BP, edema
