A nurse is preparing to teach a new client with rheumatoid arthritis about their prescribed medication, etanercept. Which client statement indicates the nurse's teaching was effective regarding the medication's action and necessary precautions?

A. Etanercept is a tumor necrosis factor (TNF) inhibitor that suppresses the immune system. Taking immune-boosting herbal supplements like echinacea may interact with the medication or worsen immune suppression, and clients should always consult their healthcare provider before using herbal or over-the-counter products. B. Clients should not stop etanercept abruptly based on temporary symptoms such as joint pain or swelling. The medication works over time to reduce inflammation and prevent disease progression, and discontinuing it without guidance can lead to worsening of rheumatoid arthritis. C. Etanercept suppresses the immune system, which increases the client’s susceptibility to infections, including serious bacterial, viral, and fungal infections. Clients should monitor for fever, cough, shortness of breath, or other signs of infection and report them immediately. This demonstrates proper understanding of both the medication’s mechanism of action and necessary precautions. D. Live vaccines should be avoided while taking etanercept, but inactivated vaccines, such as flu and pneumonia vaccines, are generally recommended to help prevent infections. The statement is too broad and indicates a misunderstanding of vaccination precautions.
