Question 1 of 5
A nurse is caring for a client who is taking warfarin and reports taking several new herbal supplements. The nurse should identify that which of the following supplements is contraindicated for concurrent use with warfarin?
Correct Answer: D
Rationale: The correct answer is D: Ginkgo biloba. Ginkgo biloba may increase the risk of bleeding when taken with warfarin due to its antiplatelet effects. Warfarin is an anticoagulant that works by inhibiting blood clotting factors. When combined with Ginkgo biloba, which also has anticoagulant properties, the risk of bleeding is significantly increased. Probiotics (
A), Coenzyme Q10 (
B), and Valerian (
C) do not have known interactions with warfarin that would increase the risk of bleeding. In summary, Ginkgo biloba is contraindicated due to potential additive anticoagulant effects, while the other options are safe to use concurrently with warfarin.
