A nurse is reviewing statements made by a colleague about the medical management of a patient with hepatic encephalopathy receiving lactulose, rifaximin, and a protein-restricted diet. Which statement made by the nurse is incorrect?

Lactulose works by reducing ammonia levels through increased excretion in the intestines.

Monitoring for electrolyte imbalances, especially hypokalemia, is important due to lactulose-induced diarrhea.

Rifaximin is a systemic antibiotic that is used to treat viral hepatitis that may lead to hepatic damage.

Limiting dietary protein intake helps reduce ammonia production from protein metabolism in the gut.
