Chronic renal failure

Chronic renal failure ( 47 Questions)

A client with chronic renal failure asks the nurse about the purpose of the glomerular filtration rate (GFR) test. What is the nurse's best response?


Correct Answer: C

A. Incorrect. The volume of urine produced in 24 hours is measured through a different test called the 24-hour urine collection, not the GFR test.

B. Incorrect. The GFR test does not assess blood glucose levels; it is primarily used to evaluate kidney function.

C. Correct. The GFR test measures how well the kidneys are filtering waste and fluids from the blood. It is an important indicator of kidney function and is commonly used to stage chronic renal failure.

D. Incorrect. The GFR test does not specifically measure the excretion of potassium and sodium in the urine; instead, it focuses on overall kidney function and filtration rate.
