Question

Quizplus · Accepted Answer

Creatinine is constantly released from muscle and excreted primarily by glomerular filtration.In chronic kidney disease (CKD),as glomerular filtration rate (GFR)declines,the plasma creatinine level increases by a reciprocal amount to maintain a constant rate of excretion.As GFR continues to decline,plasma creatinine concentration increases.
Creatinine is elevated; potassium is also elevated.
Metabolic acidosis develops.
Decreased urea clearance occurs.
