A client with chronic renal failure asks the nurse about dietary restrictions. What should the nurse emphasize as a key dietary modification for managing the condition?
Limiting protein intake to preserve kidney function.
Increasing sodium intake to balance electrolytes.
Consuming potassium-rich foods to prevent deficiency.
Avoiding fluid restrictions to maintain hydration.
The Correct Answer is A
A. Correct. In chronic renal failure, limiting protein intake is essential to reduce the workload on the kidneys and slow the progression of kidney damage.
B. Incorrect. Increasing sodium intake is not recommended in chronic renal failure, as it can lead to fluid retention and hypertension.
C. Incorrect. While potassium intake may need to be adjusted based on blood levels, there is no indication to consume potassium-rich foods to prevent deficiency.
D. Incorrect. Fluid restrictions are typically necessary in chronic renal failure to prevent fluid overload and related complications.

Correct Answer is A
Explanation
A. Correct. The GFR test measures how well the kidneys are filtering waste and fluids from the blood. It is an essential indicator of kidney function and is commonly used to diagnose and stage chronic renal failure.
B. 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.
C. Incorrect. While the GFR test is used to assess kidney function, it is not specific to diagnosing particular kidney diseases like glomerulonephritis.
D. Incorrect. The GFR test does not specifically assess the excretion of potassium and sodium in the urine; instead, it focuses on overall kidney function and filtration rate.
Correct Answer is B
Explanation
A. Incorrect. A GFR value of 10 mL/min/1.73m² indicates severe kidney dysfunction, not mild impairment.
B. Correct. A GFR value of 10 mL/min/1.73m² is considered very low and indicates severe kidney dysfunction. At this level, the kidneys are severely damaged and unable to effectively filter waste and fluids from the blood.
C. Incorrect. A GFR value of 10 mL/min/1.73m² is much lower than the threshold for moderate kidney dysfunction.
D. Incorrect. A GFR value of 10 mL/min/1.73m² is far below the normal range and indicates significant kidney dysfunction, not normal kidney function.
