A nurse is reviewing the GFR test results for a client with chronic renal failure. The GFR value is 50 mL/min/1.73m². How should the nurse interpret this result?
The client has normal kidney function.
The client has mild kidney impairment.
The client has moderate kidney dysfunction.
The client's kidneys are severely damaged.
The Correct Answer is C
A. Incorrect. A GFR value of 50 mL/min/1.73m² indicates some level of kidney dysfunction, not normal kidney function.
B. Incorrect. A GFR value of 50 mL/min/1.73m² indicates moderate kidney dysfunction, not mild impairment.
C. Correct. A GFR value of 50 mL/min/1.73m² is considered to represent moderate kidney dysfunction. This level of GFR indicates that the kidneys are not effectively filtering waste and fluids from the blood.
D. Incorrect. While a GFR value of 50 mL/min/1.73m² indicates kidney dysfunction, it does not represent severe kidney damage. Severe kidney dysfunction would have a much lower GFR value.

C. Incorrect. A GFR value of 60 mL/min/1.73m² is not considered moderate kidney dysfunction. It is within the mild impairment range.
D. Incorrect. A GFR value of 60 mL/min/1.73m² is not indicative of severely damaged kidneys. Severe kidney dysfunction would have a much lower GFR value.
