A nurse is admitting a client who states he takes ginkgo biloba every day to improve his memory. The nurse should identify a potential interaction with which of the following medications the client is taking?
Correct answer
C
Rationale
The correct answer is C: Warfarin. Ginkgo biloba can interact with warfarin, an anticoagulant, by increasing the risk of bleeding due to its antiplatelet effects. Ginkgo biloba can also interfere with the metabolism of warfarin, leading to changes in its effectiveness. The other choices (A, B, and D) do not have known interactions with ginkgo biloba. Levothyroxine, famotidine, and loratadine are not typically associated with significant interactions with ginkgo biloba.
