Answer to Question 1

ANS: A
Latanoprost can cause a harmless, heightened brown pigment of the iris that stops when the medication is discontinued but does not regress. It is not a sign of a toxic reaction. It does not indicate an increased risk of developing migraines. It will not reverse.

Answer to Question 2

ANS: A
Over time, resistance to imatinib may develop because the genes that code for BCR-ABL can mutate. Side effects of imatinib are not dose-dependent. Imatinib has significant drug interactions with several drugs. Imatinib is given orally.
