Final answer:
The nurse should recommend a low protein, high carbohydrate, low sodium, high potassium diet for a client in acute renal failure.
Step-by-step explanation:
The nurse should recommend a low protein, high carbohydrate, low sodium, high potassium diet for a client in acute renal failure. In acute renal failure, the kidneys are unable to effectively filter waste products and excess fluid from the blood. Limiting protein intake helps reduce the workload on the kidneys, while carbohydrates provide energy. Low sodium intake is important to prevent fluid retention, and high potassium levels can be beneficial for cardiac health in this population.
