| Question | Answer |
|---|---|
| how do diuretics work | reduce circulatory volume through excretion of fluid via kidneys |
| 4 main categories of antihypertensives | beta blockers, ACE inhibitors, diuretics, calcium channel blockers |
| digoxin/lanoxin | cardiac glycosides |
| captopril, aldomet, propanolol, tenormin, lopressor, methyldopa, minipress, hydrochlorothiazide (HCTZ) | antihypertensives |
| warfarin (Coumadin), heparin | anticoagulants |
| lasix, hydrodiuril, aldactone | diuretics |
| drug category used for tx of HTN, angina, tachyarrhythmias, MI, glaucoma | beta blockers |
| drug used for tx of HTN, angina, arrthymias | calcium channel blockers |
| nimodipine, Procardia, verapril | calcium channel blockers |
| propanolol, lopressor, tenormin | beta blockers |
| nursing measures for calcium channel blockers | hold if B/P less than 100/60 |
| beta blockers - nsg measures | hold if HR <60 |
| how beta blockers work | decreases sympathetic nervous system resulting in decreased BP, HR, contractility, cardiac output, renin activity |
| how ACE inhibitors work | block production of angiotensin II, a potent vasoconstrictor. reduces peripheral arterial resistance and BP |
| how calcium channel blockers work | prevent movement of extracellular calcium into the cell which vasodilates |
| how antihypertensives in general work | lowers BP by decreasing circulatory volume, dilation of blood vessels or blocking beta receptors |
