Diuretics

Question 1

Reasons for prescribed diuretics

Answer 1

prescibred to decrease salt and fluid retention: decreases Na+ which decreases plasma volume; decreases BP

Question 2

Common prescribed conditions

Answer 2

hypertension; heart failure; diabetics

Question 3

Osmosis diuretics

Answer 3

prevents re-absorption of Na+ and H2O; increases solute concentration which increases retention in tubules; increases excretion through urine

Question 4

Loop diuretics

Answer 4

works at loop of Henle: inhibits chloride re-absorption causing increased Na+ and K+ retention in tubules; ions are then excreted

Question 5

Thiazide diuretics

Answer 5

inhibits Na+ and CI- from re-absorption; increases excretion; can increase plasma acidic levels

Question 6

Potassium-sparing diuretics

Answer 6

decreases re-absorption of Na+ without decreasing K+ excretion

Question 7

Furosemide

Answer 7

Loop diuretic

Question 8

Hydrochlorothiazide

Answer 8

Question 9

Bumetanide

Answer 9

Loop diuretic

Question 10

Answer 10

Thiazide diuretic

Question 11

Amiloride

Answer 11

K+ sparing diuretic

Question 12
