Correct Answer is C
Explanation
A. Hypertension as a result of the increased, concentrated blood volume: Hypertension in chronic kidney disease is due to fluid overload and renin-angiotensin-aldosterone system activation, not erythropoietin deficiency.
B. Elevated lipid levels in the bloodstream, contributing to accelerated atherosclerosis: Dyslipidemia in chronic kidney disease is unrelated to erythropoietin deficiency.
C. Anemia as a result of the diminished number of red blood cells being produced: Erythropoietin stimulates red blood cell production; its deficiency in chronic renal failure leads to anemia.
D. Diminished immunologic function with fewer white blood cells: White blood cell production is not directly affected by erythropoietin deficiency.
