A nurse is reinforcing teaching with a client who has a new prescription for warfarin. The nurse should identify which of the following over-the-counter medications as safe for use with warfarin?

A. Docusate is correct. Docusate is a stool softener, and it does not have a significant effect on blood clotting. Therefore, it is considered safe for use with warfarin, which requires careful monitoring to avoid interactions that may increase bleeding risks. B. Ibuprofen is incorrect. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID. that can increase the risk of bleeding when used with warfarin by inhibiting platelet aggregation and affecting clotting factors. C. Aspirin is incorrect. Aspirin also inhibits platelet function, increasing the risk of bleeding when combined with warfarin. This combination should be avoided unless specifically prescribed. D. Omeprazole is incorrect. Although omeprazole is often used to treat gastrointestinal issues, it may interact with warfarin and affect its metabolism. This interaction can increase the risk of bleeding, and caution is recommended when using these medications together.
