A female client with multiple sclerosis reports having less fatigue and improved memory since she began using the herbal supplement, ginkgo biloba. Which information is most important for the nurse to include in the teaching plan for this client?

A. Gingko biloba use should be limited and not taken during pregnancy: While this is true, the client in question is using it for multiple sclerosis-related symptoms and not indicated to be pregnant. This point is valid but not the most immediate safety concern for her situation.B. Nausea and diarrhea can occur when using this supplement: These are known side effects of ginkgo biloba but are generally mild and not life-threatening. They are less critical to emphasize than potentially dangerous drug interactions.C. Anxiety and headaches increase with the use of ginkgo: While some users may experience headaches, the occurrence of anxiety is less common. These effects are not as significant or dangerous as those involving bleeding risks when ginkgo is combined with other medications.D. Aspirin and nonsteroidal antiinflammatory drugs (NSAID) interact with ginkgo: Ginkgo biloba has antiplatelet properties and can increase the risk of bleeding, especially when taken with aspirin or NSAIDs. This interaction is potentially serious and is the most important safety information to provide.
