The nurse should inform a client taking carbamazepine (Tegretol) that it can affect other medications in which of the following ways?
Correct answer
A
Rationale
Carbamazepine induces liver enzymes, reducing the effects of oral anticoagulants like warfarin by increasing their metabolism. It does not typically affect verapamil, other anticonvulsants, or contraceptives in the ways described.
