The amount of potassium excreted by the kidney will decrease if:

a) Distal tubular flow increases: This is incorrect. An increase in distal tubular flow would actually increase the amount of potassium excreted by the kidney. This is because the rate of flow can affect the amount of potassium that is reabsorbed back into the body. A faster flow rate means less time for reabsorption, leading to more potassium being excreted.

b) Circulating aldosterone level increase: This is correct. Aldosterone increases the reabsorption of sodium ions and water, but increases the excretion of potassium ions in the urine. Therefore, an increase in aldosterone would decrease the amount of potassium excreted by the kidney.

c) Dietary intake of potassium increase: This is incorrect. An increase in dietary intake of potassium would actually increase the amount of potassium excreted by the kidney. This is because the body would need to get rid of the excess potassium to maintain a balance.

d) Na+ reabsorption by the distal nephron decreases: This is correct. If less sodium is reabsorbed, then less potassium is excreted. This is because sodium reabsorption and potassium excretion are linked processes in the kidney.

e) The excretion of organic ions increase: This is incorrect. The excretion of organic ions would not directly affect the amount of potassium excreted by the kidney.
