Question 2 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.
Question 3 of 5
Typically, as GFR increases, the [Naâº] of the filtrate reaching the DCT will
Correct Answer: A
Rationale: Higher GFR (A) increases filtrate volume, reducing PCT reabsorption time, raising Na⺠concentration reaching the DCT. Decrease (B) or no change (C) assumes full compensation, but faster flow elevates Naâº, making A correct.
Question 4 of 5
A nurse reviews the health history of a client with an oversecretion of renin. Which disorder should the nurse correlate with this assessment finding?
Correct Answer: B
Rationale: Excess renin increases blood pressure via aldosterone, making hypertension the correlated disorder.
