Of the following, which is TRUE of the changes in blood chemistry and composition in a patient with chronic renal failure?

B) H+ excretion leads to alkalosis.
C) Polycythemia occurs.
D) Urea and creatinine levels increase.

Question

Quizplus · Accepted Answer

Chronic renal failure leads to a decrease in the glomerular filtration rate, resulting in a buildup of waste products such as urea and creatinine in the blood. Therefore, urea and creatinine levels increase in a patient with chronic renal failure. Blood glucose levels may be elevated in some cases of chronic renal failure due to insulin resistance, so A is false. H+ retention leads to acidosis, not alkalosis, so B is false. Polycythemia is not a typical finding in chronic renal failure, so C is false.
