Which of the following is caused by a deficiency of erythropoietin?
Glycosuria
Polyuria
Anemia
Oliguria
The Correct Answer is C
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.
