A client with chronic renal failure is prescribed a low-protein diet. What is the primary reason for this dietary restriction?
To reduce the risk of hyperkalemia
To prevent fluid overload
To minimize the risk of metabolic acidosis
To decrease the accumulation of nitrogenous waste products
The Correct Answer is D
A) Incorrect. Limiting protein intake can help manage nitrogenous waste products, but it is not the primary reason for a low-protein diet.
B) Incorrect. Fluid overload is managed by restricting fluid intake, not protein intake.
C) Incorrect. The primary treatment for metabolic acidosis in chronic renal failure is bicarbonate supplementation, not a low-protein diet.
D) Correct. A low-protein diet is prescribed to reduce the production of nitrogenous waste products, such as urea and creatinine, which the damaged kidneys are unable to efficiently excrete. This helps prevent the buildup of waste products in the body.

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.
Correct Answer is A
Explanation
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.
