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.

Correct Answer is B
Explanation
A. Incorrect. Encouraging the client to drink 3 liters of fluid daily may be excessive and can contribute to fluid overload in individuals on hemodialysis. Fluid intake needs to be limited and closely monitored.
B. Correct. Monitoring the vascular access site is crucial to detect early signs of infection or clotting, which can lead to serious complications such as sepsis or thrombosis.
C. Incorrect. Phosphate binders are used to control phosphate levels in the blood and are generally taken with meals, not specifically before hemodialysis sessions.
D. Incorrect. Promoting a high-potassium diet is not appropriate for individuals on hemodialysis, as it can lead to hyperkalemia. Clients on hemodialysis typically need to restrict potassium intake.
Correct Answer is B
Explanation
A. Incorrect. Pruritus (itching) is a common symptom of chronic renal failure and is related to the buildup of waste products and toxins in the blood, leading to skin irritation.
B. Correct. Pruritus is a common and distressing symptom of chronic renal failure, caused by the retention of uremic toxins in the blood. These toxins can irritate the skin and lead to itching.
C. Incorrect. While medications can sometimes cause pruritus as a side effect, it is not the primary cause of itching in clients with chronic renal failure.
D. Incorrect. Persistent pruritus in a client with chronic renal failure is not necessarily indicative of an allergic reaction to medications. It is more likely related to the buildup of waste products in the blood.
