A nurse is caring for a client who is taking naproxen following an exacerbation of rheumatoid arthritis. Which of the following statements by the client requires further discussion by the nurse?

A. "I've been taking an antacid to help with indigestion." – This statement is expected. Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that can irritate the gastrointestinal tract. Taking an antacid may help reduce GI discomfort and is a common recommendation. B. "I signed up for a swimming class." – This is an appropriate activity for a client with rheumatoid arthritis. Swimming is a low-impact exercise that helps maintain joint flexibility and strength. C. "The naproxen is easier to take when I crush it and put it in applesauce." – This statement requires follow-up. Naproxen is often formulated as an enteric-coated or extended-release tablet to protect the stomach lining or to ensure proper absorption. Crushing it can destroy this protective mechanism, increasing the risk of GI irritation or altering drug effectiveness. D. "I've lost 2 pounds since my appointment 2 weeks ago." – Mild weight fluctuations are not uncommon and may not be directly related to the medication. Unless weight loss is severe or unexplained, it does not require immediate concern in this context.
