VUSN Pharm 5106 Diuretics Exam Study
Guide with Complete Solutions
Overview of diuretics - Answer✔️✔️-block sodium (and thus water) and
chloride reabsoprtion
increase in urine flow is directly related to the amount of Na and Cl
reabsorption it blocks
diuretics that block reabsorption early in the nephron have potential of
creating the greatest effect
the more proximal to the bowmans capsule and the more distal to the
collecting duct = the more powerful the diuretic
What are the classifications of diuretics? - Answer✔️✔️-high ceiling or loop
diuretics - Lasix
thiazide diuretics - Hydrochlorothiazide
osmotic diuretics - Manniotl
potassium sparing diuretics
