Question

Quizplus · Accepted Answer

Elevated plasma creatinine level is a marker of impaired renal function, as the kidneys are responsible for filtering creatinine from the blood. Decreased plasma potassium level and metabolic alkalosis are not typically associated with renal failure, while increased urea clearance may actually indicate improved renal function.
