nur 206 htn medication

-artan

angiotensin II receptor blocker

-olol

beta blocker

-pril

ACE inhibitor

-azosin

alpha blocker

what drug class is clonidine in

adrenergic inhibitors

-pine

calcium channel blockers

what drug class is hydralazine in

direct vasodilators

what drug class is nitroglycerin in

direct vasodilators

-ide

loop diuretics

-ide

thiazide diuretics

mechanism of action for -artan

prevents angiotensin II from binding to receptors in blood vessel walls = vasodilation & increase sodium and water excretion

mechanism of action for -olol

blocks beta-1 adrenergic receptors = decrease CO and reduce sympathetic vasoconstriction; decreases renin secretion

mechanism of action for -pril

preventions angiotensin I from turning into angiotensin II; prevents vasoconstriction & sodium and water retention

mechanism of action for -azosin

blocks alpha adrenergic effects producing vasodilation; decreases SVR & BP

mechanism of action for adrenergic inhibitors

decrease SNS stimulation; decreases SVR & BP

mechanism of action for -pine

increase sodium excretion and cause vasodilation by preventing calcium into cells; smooth muscle relaxation = decreased SVR & BP

mechanism of action for direct vasodilators

relax vascular smooth muscle & reduce SVR

mechanism of action for loop diuretics

inhibit NaCl reabsorption into loop of Henle = increased NaCl & water excretion and reduced SVR

mechanism of action for thiazide diuretics

inhibit NaCl reabsorption in the distal convoluted tubule + increased NaCl & water secretion and decreased SVR

nursing considerations for -artan

can take 3-6 weeks to take full effect

nursing considerations for -olol

monitor bp & pulse before taking medication

hold if hr is <60 bpm

less effective bp reduction in african american patients

nursing considerations for -pril

ASA & NSAIDs may reduce effectiveness

avoid with K sparing diuretics

can increase serum creatinine

can cause dry hacking cough

nursing considerations for -azosin

take at bedtime to prevent orthostatic hypotension

nursing considerations for adrenergic inhibitors

avoid sudden discontinuation to reduce withdrawal symptoms

chew gum or candy for dry mouth

reposition slowly

nursing considerations for -pine

avoid grapefruit

use cautiously with CHF patients

nursing considerations for direct vasodilators

use for hypertensive crisis

monitor for hypotension

nursing considerations for loop diuretics & thiazide diuretics

monitor for orthostatic hypotension

monitor for electrolyte imbalance

monitor I&O, edema, lung sounds, weight
