Which of the following is most likely to cause polyuria?
A)Oversecretion of aldosterone
B)Decreased glomerular filtration rate (GFR)
C)Deficiency of ADH
D)Activation of angiotensinogen

Question

Quizplus · Accepted Answer

Polyuria is excessive urine output, which is most commonly seen in conditions where there is a deficiency of antidiuretic hormone (ADH) such as diabetes insipidus. ADH is responsible for reabsorption of water in the kidneys, hence a deficiency of ADH leads to decreased reabsorption of water and increased urine output. Oversecretion of aldosterone (A) and activation of angiotensinogen (D) are more likely to cause fluid retention and decreased urine output, while decreased GFR (B) can lead to decreased urine output due to decreased filtration.
