A client receives a prescription for methotrexate. Which information provided by the client requires additional instruction by the nurse?

A. Obtain a platelet count weekly: Regular monitoring of platelet counts is important for clients on methotrexate due to the risk of bone marrow suppression and potential thrombocytopenia. This instruction is appropriate and necessary. B. Take the medication during pregnancy: Methotrexate is contraindicated during pregnancy due to its teratogenic effects and potential to cause fetal harm. It is crucial for clients to avoid using methotrexate while pregnant or planning to become pregnant. C. Use folic acid to protect the liver: While folic acid is often used to help reduce the side effects of methotrexate, particularly its gastrointestinal effects and potential for liver toxicity, it is not used to "protect the liver" per se. The correct approach is to use folic acid as directed by a healthcare provider, often to mitigate some of the side effects of methotrexate. D. Store the medication at room temperature: Methotrexate should be stored according to the manufacturer's instructions, which usually involve keeping it at room temperature. This information is correct and does not require additional instruction.
