Question 1 of 5
Which of the following promotes sodium retention and potassium loss from the blood across the wall of the distal convoluted tubule?
Correct Answer: C
Rationale: Aldosterone (C) increases sodium reabsorption and potassium secretion in the distal tubule, regulating electrolytes. Renin (A) triggers the RAAS, angiotensin II (B) stimulates aldosterone, and angiotensin I (D) is a precursor, making C the direct effector.

Rationale: Excess renin increases blood pressure via aldosterone, making hypertension the correlated disorder.
