A patient with hepatic encephalopathy is receiving lactulose.Which assessment provides the nurse with the best information to evaluate the patient’s therapeutic response to the drug?

Choice A rationaleWhile changes in stool color and character can be indicative of various health conditions, they are not the best indicators of a patient’s therapeutic response to lactulose in the context of hepatic encephalopathy.Choice B rationaleFingerstick glucose monitoring is important in managing conditions like diabetes, but it does not provide the best information to evaluate a patient’s therapeutic response to lactulose in the context of hepatic encephalopathy.Choice C rationaleLactulose is used in the management of hepatic encephalopathy, a condition that can occur in patients with severe liver disease. It works by reducing the absorption of ammonia in the gut, which is a toxin that can accumulate in the blood in patients with liver dysfunction. Therefore, monitoring serum electrolytes and ammonia levels can help evaluate the effectiveness of lactulose therapy.Choice D rationaleWhile monitoring serum hepatic enzymes can provide valuable information about liver function, it does not provide the best information to evaluate a patient’s therapeutic response to lactulose in the context of hepatic encephalopathy.
