CMSRN Review Exam Questions & Answers 2024/2025 ADH (Antidiuretic Hormone) - ANSWERS-Secreted by the pituitary gland -Promotes reabsorption of water back into the blood -Creates small amounts of dilute urine -Released when osmolarity is high and when there is low ECF -"Tap water hormone" Aldosterone - ANSWERS-Secreted by the adrenal cortex -Promotes reabsorption of sodium and water back into the blood -Creates a small volume of urine with a low concentration -Released when angio...

CCRN Exam Questions and Answers 100% Pass Where is ADH made? - Answer- Hypothalamus Where is ADH Stored? - Answer- Posterior Pituitary Where does ADH act to make the kidneys hold onto water? - Answer- Distal Convoluted & Collecting Tubules Disease of too much ADH = too much water! The increased ADH causes less urine output, decreased Na levels (dilutional hyponatremia) & Hypo-osmolarity. It is caused from Oat Cell Carcinioma, Viral PNA or head problems, also sometimes anesthesia, analges...

BRS PHYSIOLOGY EXAM QUESTIONS AND ANSWERS VERIFIED GRADED A++ LATEST UPDATE 1. Secretion of K+ by the distal tubule will be decreased by (A) metabolic alkalosis (B) a high-K+ diet (C) hyperaldosteronism (D) spironolactone administration (E) thiazide diuretic administration The answer is D [VB4b].Distal K+ secretion is decreased by factors that decrease the driving force for passive diffusion of K+ across the luminal membrane. Because spirono- lactone is an aldosterone antagonist, it reduc...
