A client with acute renal failure is prescribed a low-phosphate diet. What foods should the nurse include in the client's diet plan?

A. Correct. Nonsteroidal anti-inflammatory drugs (NSAIDs), including ibuprofen, are known to cause kidney damage and are a common cause of intrinsic acute renal failure, especially when used in high doses or for extended periods.

B. Incorrect. Loop diuretics, such as furosemide, are not typically associated with intrinsic acute renal failure.

C. Incorrect. Metformin is not a common cause of intrinsic acute renal failure. However, it is contraindicated in individuals with severe kidney impairment.

D. Incorrect. While ciprofloxacin and other antibiotics may have renal-related side effects, they are not a common cause of intrinsic acute renal failure.

A. Incorrect. While protein intake may need to be adjusted in acute renal failure, increasing protein intake is not typically recommended during the acute phase, as it may place additional stress on the kidneys.

B. Correct. Limiting potassium-rich foods is essential for clients with acute renal failure, as impaired kidney function can lead to hyperkalemia (high potassium levels), which can be life-threatening.

C. Incorrect. A high-sodium diet is not recommended in acute renal failure, as it can exacerbate fluid retention and fluid overload.

D. Incorrect. Fluid restriction is not typically recommended in acute renal failure, especially if the client is experiencing fluid depletion and dehydration.
