Q

Bumex/Bumetanide, Lasix/Furosemide, Demadex/Torsemide

LOOP DIURETICS

A

Antihypertensive action-renal vasodilation: provides increase GFR and decrease in peripheral vascular resistance
More potent than thiazide diuretics-cause rapid diuresis resulting in decreased vascular fluid volume, decreased cardiac output, and decreased BP
Need to be taken early to avoid nocturia
IV doses need to be given SLOWLY to avoid hypotension and ototoxicity (hearing loss)

26
Loop diuretics with sulfonyureas may?
May cause hypoglycemia
27
What should you monitor for loop diuretics?
``` Monitor electrolytes, especially Na & K Monitor H & H-hemoconcentration BUN, Cr, and LFT Glucose Lithium levels Monitor VS-BP & P, Weight, I&O Assess for dehydration ```
28
What should you educate regarding loop diuretics?
EDUCATE Patient to eat food rich in K, Weigh daily, Avoid orthostatic hypotension, report ringing in the ears
29
Thiazide Diuretics
Hypotensive effect may be due to direct arteriolar vasodilation and decreased peripheral resistance-used for edema and HTN Not effective for immediate diuresis Hydrochlorothiazide/HCTZ/Hydrodiuril, Lozol/Indapamide, Zaroxylin/Metolazone, Polythiazide/Minizide
30
What would happen if you combine Thiazide Diuretics with lithium?
Lithium-if used concomitant, will increase lithium levels
31
What do you look for if Thiazide Diuretics are with sulfonylureas and insulin?
Increase potential for hypoglycemia
32
What does NSAIDS do to thiazide diuretics?
Decrease
33
What happens when you add loop and thiazide diuretics?
Increases

46
What is ACE inhibitors?
Angiotensin Converting Enzyme inhibitors: inhibit the renin-angiotensin-aldosterone mechanism by blocking conversion of angiotensin I to angiotensin II and prevent vasoconstriction Used to treat HTN Used to prevent kidney failure in patients with diabetes

May increase Digoxin concentration
52
Antacids do what to Ace Inhibitors?
Decrease Absorption
53
Foods high in fat may do what do Ace Inhibitors?
Impair Drug Absorption
54
What are SE of Ace Inhibitors?
Dry, hacking cough May increase BUN and Cr, LFT, bilirubin, uric acid and blood glucose Headache, dizziness, fatigue, hypotension
55
What is the Adverse effect of angioedema?
angioedema
56
What should you do for ACE inhibtors.
