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. Reduce the client's intake of protein is correct because excess dietary protein increases ammonia production during digestion, worsening hepatic encephalopathy. Reducing protein helps decrease ammonia levels. B. Administer diuretics is incorrect because diuretics help manage fluid retention and ascites, not ammonia levels. C. Administer vitamin K is incorrect because vitamin K is given to improve clotting function in clients with liver disease, but it does not reduce ammonia. D. Restrict the client's intake of fluids is incorrect because fluid restriction is used for hyponatremia or ascites management, not ammonia reduction.
