Correct Answer is C
Explanation
A. Diuretics are used to manage ascites and fluid retention, not to reduce ammonia levels.
B. Fluid restriction may be needed in cases of hyponatremia but does not directly impact ammonia levels.
C. Reducing protein intake helps decrease ammonia production since protein metabolism in the gut generates ammonia, which the diseased liver cannot adequately clear.
D. Vitamin K is used to improve clotting in liver disease but has no effect on ammonia levels.
Correct Answer is A
Explanation
A. Lactulose is prescribed to reduce ammonia levels in clients with hepatic encephalopathy. It works by promoting the excretion of ammonia through increased bowel movements. Loose stools are expected and indicate the medication is working.
B. Antidiarrheals would counteract the purpose of lactulose and are not appropriate.
C. Stopping the medication due to loose stools would prevent ammonia clearance and may worsen the client’s condition.
D. A stool specimen is not necessary unless there are signs of infection or abnormal characteristics not explained by the medication.
