Question

14 of 50 a client diagnosed with hepatic encephalopathy is receiving lactulose. the nurse determines that the medication is effective if which finding is observed? answer options 1 there is an absence of blood in emesis and stool 2 urine output increases from 250 to 400 ml per 8 - hour shift. 3 episodes of frequent liquid bowel movements diminish to one time per day 4 the client who was previously oriented to person only can now state name, year, and present location

Explanation:

Lactulose is used to treat hepatic encephalopathy by reducing ammonia levels in the blood. Improvement in mental - status (from being oriented to person only to being able to state name, year, and present location) indicates that the drug is effective as ammonia - related cognitive impairment is being reversed. Absence of blood in emesis and stool is related to gastrointestinal bleeding, not directly to lactulose's effect on hepatic encephalopathy. Increase in urine output is related to diuretic action and not lactulose's action in hepatic encephalopathy. Decrease in liquid bowel movements is not the key indicator of lactulose's effectiveness in treating hepatic encephalopathy.

Answer:

1. The client who was previously oriented to person only can now state name, year, and present location.
