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.
Correct Answer is B
Explanation
A. Specific gravity: Specific gravity measures urine concentration but does not directly assess renal function.
B. Creatinine: Serum creatinine levels provide the most accurate measure of renal function as they reflect the kidney’s ability to filter waste.
C. Phosphates: Phosphate levels are affected by kidney function but are not the most direct measure.
D. BUN: Blood Urea Nitrogen (BUN) can be affected by other factors like hydration and protein intake, making it less reliable than creatinine.
