Quizplus · Accepted Answer

The creatinine clearance test measures the rate at which nitrogenous waste (creatinine) is removed from the blood by comparing its concentration in the blood and urine over a 24-hour period. BUN (A) measures the amount of nitrogen in the blood that comes from urea, a byproduct of protein breakdown. CAPD (B) is a form of dialysis that uses the lining of the abdomen (peritoneum) as the filter, and ESWL (C) is a noninvasive procedure that uses shock waves to break up kidney stones.
