Final answer:
The nurse should inform the client in end-stage kidney failure who requires dialysis three times a week that the intake of protein should be decreased due to the progressively failing function of the kidney. The correct option is d.
Step-by-step explanation:
The nurse should inform the client in end-stage kidney failure who requires dialysis three times a week that the intake of protein should be decreased due to the progressively failing function of the kidney. Proteins are filtered by the kidneys, and when the kidneys are failing, they are not able to effectively filter out protein from the blood.
This can lead to protein loss and contribute to further kidney damage. Therefore, reducing protein intake can help prevent nitrogenous waste buildup and reduce excretory load on the kidneys.
Therefore, the correct option is d.
