Answer to Question 1

ANS: C
Lactulose is the only laxative known to lower ammonia levels in patients with portal hypertension and hepatic encephalopathy secondary to liver disease.
Lactulose does not work to reduce cerebral edema, nor is there any indication the patient is experiencing it.
Lactulose does not work to reduce abdominal ascites.
Lactulose does not reduce liver enzymes.

Answer to Question 2

ANS: A, B, C
Drugs that most likely would contribute to constipation are the opioids (oxycodone/acetaminophen), anticholinergics (benztropine), and some antacids (aluminum hydroxide).
Ranitidine and diazepam are not associated with constipation.
