Erythropoietin is a hormone produced by the kidney. What will a deficiency of erythropoietin in a patient in chronic renal failure result in?
Hypertension as a result of the increased, concentrated blood volume.
Elevated lipid levels in the bloodstream, contributing to accelerated atherosclerosis.
Anemia as a result of the diminished number of red blood cells being produced.
Diminished immunologic function with fewer white blood cells.
The Correct Answer is C
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.

Correct Answer is C
Explanation
A. Potassium: Potassium levels may rise in kidney dysfunction but are not directly related to increased glomerular permeability.
B. Sodium: Sodium imbalance occurs in kidney dysfunction but is not a direct result of glomerular permeability.
C. Proteins: Increased permeability in glomerulonephritis allows proteins to leak into the urine, resulting in proteinuria.
D. Water: Water imbalance can occur, but it is not related to glomerular permeability.
Correct Answer is A
Explanation
A. “It is a normal postoperative expectation.” Hematuria is common immediately after renal transplantation due to surgical trauma and typically resolves as healing occurs.
B. “It is related to the immunosuppressant drugs taken before transplantation.” Immunosuppressant drugs do not cause hematuria directly.
C. “It is caused by dye injected during surgery.” Dye is not routinely used in renal transplantation, and hematuria would not be related to this.
D. “It is caused by a small vessel that may be bleeding but will coagulate as urine flow increases.” While small vessel bleeding can occur, it is better to explain the hematuria as a normal postoperative expectation.
