Answer to Question 1

ANS: A
The major side effects of interferon are flulike symptoms with chills, fever, fatigue, malaise, and myalgia. Acetaminophen is given to treat this initially. Changing to an IV form does not alter the side effects. Diphenhydramine is given for nausea caused by interferon alpha. It is not necessary to obtain laboratory work when these symptoms initially occur.

Answer to Question 2

ANS: B
When patients taking warfarin take gefitinib, the effectiveness of the warfarin is greatly increased, and bleeding risks increase. Carbamazepine and histamine2 blockers decrease the effectiveness of gefitinib, so decreasing the gefitinib dose or decreasing the carbamazapine or histamine2 blocker is not recommended.
