Name 4 thiazide diuretics. | Chlorthalidone, Hydrochlorothiazide, Indapamide, Metolazone |
What are the benefits of and indications for thiazide diuretics? | inexpensive, effective, effective orally; to decrease fluid volume, for severe hypertension, to enhance other antihypertensives |
What are the adverse reactions associated with thiazide diuretics? | Hypokalemia, hyperuricemia, glucose intolerance, hypercholesterolemia, sexual dysfunction |
What are the signs of hypokalemia? | Dry mouth, thirst, drowsiness, weakness, lethargy, muscle aches, tachycardia |
What are the nursing implications for thiazide diuretics? | Observe for postural hypotension, Use caution for gout, renal failure, lithium; hypokalemia increases risk for digitalis toxicity; administer potassium supplements |
What substances could potentiate postural hypotension in combination with a thiazide diuretic? | alcohol, barbiturates, narcotics |
Name 3 loop diuretics. | furosemide (Lasix), Torsemide (Demadex), Bumetanide (Bumex) |
Describe the action of loop diuretics and when they are used. | Rapid action, cause volume depletion, potent for use when thiazide diuretics fail |
What are the adverse effects of loop diuretics? | Hypokalemia, Hyperuricemia, Glucose intolerance, hypercholesterolemia, hypertriglyceridemia, sexual dysfunction, weakness |
What are the nursing implications for loop diuretics? | know that volume depletion and electrolyte depletion is rapid, observe for postural hypotension, caution with renal failure, gout, lithium; Hypokalemia increases risk for digitalis toxicity, administer potassium supplements |
Name two potassium sparing diuretics. | spironolactone and amiloride |
What are the indications for spironolactone (Aldactone) and amiloride (Midamor)? | volume depletion without significant potassium loss |

When should spironolactone (Aldactone) or amiloride (Midamor) be given in relation to meals in order to avoid GI distress? | after meals |
What are the nursing implications for potassium sparing diuretics? | watch for hyperkalemia and renal failure in those treated with ACE inhibitors or NSAIDs; Watch for increase in serum lithium levels |
Name three combination loop and potassium sparing drugs. | HCTZ and triamterene (Maxidex), HCTZ and Amiloride (Moduretic), HCTZ and Spironolactone (Aldactone) |
What is the purpose of combination loop and potassium sparing diuretics? | decrease fluid volume while minimizing potassium loss |
How are the side effects of combination diuretics altered? | Side effects of individual drugs are offset or minimized by its partner |
What are the nursing implications for a patient on a combination loop/potassium sparing diuretic? | Caution clients previously taking loop or thiazide about excess potassium in diet due to potassium sparing component of new drug; follow dose schedule so that sleep is not disrupted to get up and pee |
