The nurse gathering admission data learns that a client on anticoagulants is also taking over-the-counter medications and supplements. Which of the following supplements taken by the client could interfere with anticoagulation therapy?

Question

1. Ginkgo biloba
2. Vitamin C
3. Calcium
4. Parsley extract

Answer 1

1
Rationale 1: Ginkgo biloba is taken by clients to reduce memory loss, but it has anticoagulant properties, and so could impact therapy placing the client at risk for bleeding complications. Vitamin C and calcium supplements taken as ordered are safe, and would not impact anticoagulant therapy. There is no such thing as parsley extract.
