When lactulose (Cephulac) 30 mL four times per day is ordered for a patient with advanced cirrhosis, he complains that it causes diarrhea. The nurse explains to the patient that it is still important for him to take the drug because the drug will create which of the following actions? a. Promote fluid loss b. Prevent constipation c. Prevent gastrointestinal (GI) bleeding d. Improve nervous system function

ANS: D The purpose for lactulose in the patient with cirrhosis is to lower ammonia levels and prevent encephalopathy. Although the medication may promote fluid loss through the stool, prevent constipation, and prevent bearing down during bowel movements (which could lead to esophageal bleeding), the medication is not ordered for these purposes for this patient. REF: page 1240, Table 46-16

A physician who has never been immunized for hepatitis B is exposed to the hepatitis B virus (HBV) through a needle stick from an infected patient. What should the infection control nurse inform both the physician and patient that treatment for the exposure should include? a. Evaluation of liver function tests in 60 days b.
