Answer #1

Drugs that enhance potassium reabsorption in the DCT (Distal conllecting tubule) should not be used in chronic renal failure (CKD).

Answer - b. enhance potassium reabsorption in the DCT

Chronic kidney disease increases potassium level in the blood due to malfunction of the kidney, so the drug that enhance potassium secretion in the DCT is good in CKD but if a drug reabrorp potassium from DCT to blood circulation it again increases potassium level which can be fatal.

Here is one more review question before we put these concepts together. Which statement is true about aldosterone secretion? A. Aldosterone is secreted when low renal blood pressure activates the RAAS pathway and causes increased reabsorption of sodium from the distal tubule of the nephron and from the colon. B. Aldosterone is secreted when high renal blood pressure activates the RAAS pathway and causes increased reabsorption of sodium from the distal tubule of the nephron and from the colon. C....
