Answer to Question 1

ANS: A
Patients treated with interferon beta require evaluation of bone marrow function with CBCs and of liver function with liver function tests (LFTs) at the beginning of therapy for baseline, every 3 months for a year, and then every 6 months thereafter. Abnormal LFTs warrant discontinuation of the drug.

Answer to Question 2

ANS: D
Oral diphenhydramine can help reduce itching and erythema. Ice is used to control pain and should be used before the injection; warm, moist compresses are used after the injection. Reducing the dose of interferon will not reduce the local reaction. Continuous use of topical steroids is not recommended because of the risk of skin damage.
