A patient with chronic renal failure will have lab work to evaluate his kidney function. The nurse knows that which of the following are most accurate in predicting kidney function?
Explanation
• Creatinine clearance closely correlates with the glomerular filtration rate and tubular excretion ability. It is the most effective way to measure GFR in patients with chronic kidney disease.
• The other options all test kidney function and disease, but they can be influenced by various factors that are unrelated to kidney disease.
