• Both Statements are True

• Both Statements are False

Multiple Choice

Question 7:

Statement 1: Aldosterone stimulates Potassium Secretion.

• Statement 1 is False, Statement 2 is True

• Both Statements are True

• Both Statements are False

Multiple Choice

Question 8:

Statement 1: Acute Acidosis lead to hyperkalemia due to increased potassium secretion in principal cells.
Statement 2: Increase in GFR would result to the release of ANP which favors Potassium Reabsorption.

• Both Statements are True

• Both Statements are False

Multiple Choice

Question 9:
