A nurse is assessing a client who has been prescribed lactulose for the management of hepatic encephalopathy. Which of the following statements by the client about the effects of lactulose indicates that the nurse must provide further education?

Hepatic encephalopathy occurs when the liver is unable to adequately detoxify ammonia, leading to its accumulation and subsequent neurologic impairment. Management includes reducing intestinal ammonia production and promoting its excretion. Lactulose is commonly prescribed to trap ammonia in the gut and enhance its elimination through increased bowel movements. Client education focuses on expected gastrointestinal effects and adherence to dietary practices that support bowel function. Rationale: A. Expecting bowel movements to become more frequent and softer indicates correct understanding. Lactulose works as an osmotic laxative, drawing water into the colon and increasing stool frequency and softness. This effect is therapeutic because it helps eliminate ammonia from the gastrointestinal tract. B. Experiencing bloating as a side effect of this medication is an expected response. Lactulose is metabolized by colonic bacteria, producing gas as a byproduct, which can lead to abdominal distention and bloating. This is a common and generally manageable effect of therapy. C. Lactulose helping reduce ammonia levels in the blood demonstrates accurate understanding. The medication acidifies the colon, converting ammonia (NH₃) into ammonium (NH₄⁺), which cannot be absorbed and is excreted in stool. This process lowers systemic ammonia levels and improves neurologic symptoms. D. Avoiding all fiber intake while taking lactulose is incorrect and requires further education. Dietary fiber actually supports bowel regularity and enhances the effectiveness of lactulose by promoting stool bulk and intestinal motility. Completely eliminating fiber may worsen constipation and reduce overall gastrointestinal function, which is counterproductive in managing hepatic encephalopathy.
