A nurse is planning care for a client who has end-stage cirrhosis of the liver with encephalopathy. Which of the following interventions should the nurse plan to implement to decrease the client's ammonia level?

A. Administer vitamin K: Vitamin K is used to manage bleeding disorders related to cirrhosis, not to decrease ammonia levels. Ammonia buildup is more related to liver function than coagulation. B. Restrict the client's intake of fluids: Fluid restriction is typically used in cases of fluid overload or hyponatremia, not specifically to decrease ammonia levels in hepatic encephalopathy. C. Reduce the client's intake of protein: Reducing protein intake helps decrease ammonia production. Ammonia is a byproduct of protein metabolism, and limiting protein can help reduce the load on the liver in patients with encephalopathy. D. Administer diuretics: Diuretics are used to manage ascites in cirrhosis, but they do not directly impact ammonia levels. Managing ammonia requires addressing liver function and protein metabolism.
