Correct Answer is C

Explanation

A. Decreased GFR (glomerular filtration rate): A low GFR would reduce urine output, not increase it.

B. Over secretion of aldosterone: Aldosterone promotes sodium and water reabsorption, which decreases urine output.

C. Decrease amounts of ADH: Antidiuretic hormone (ADH) helps retain water. A deficiency leads to diuresis, causing polyuria (as seen in diabetes insipidus).

D. Activation of angiotensinogen: This leads to vasoconstriction and aldosterone release, promoting water retention, not polyuria.

A. Glycosuria B. Polyuria C. Anemia D. Oliguria

Correct Answer is C

Explanation

A. Glycosuria: This is glucose in the urine, often caused by diabetes mellitus, not erythropoietin deficiency.

B. Polyuria: This refers to excessive urination and is unrelated to erythropoietin levels.

C. Anemia: Erythropoietin stimulates red blood cell production, so its deficiency leads to reduced RBCs, resulting in anemia.

D. Oliguria: Oliguria is low urine output often related to renal perfusion issues, not directly to erythropoietin.
