A nurse is reinforcing teaching with a client who has rheumatoid arthritis. Which of the following statements by the client indicates understanding of the information?

A. "I will schedule important tasks in the afternoon.” Rationale: Clients with RA experience fatigue and stiffness in the morning and improves with movement, so it's better to schedule important activities in the morning after stiffness improves. B. "I can use heat or cold to help relieve my pain.” Rationale: Both heat and cold can reduce pain and inflammation in RA. Heat loosens stiff joints; cold reduces swelling. C. "I need to perform range-of-motion of my joints if I notice they are red.” Rationale: Redness indicates acute inflammation; joints should be rested during flare-ups, not exercised aggressively. D. "I should stop exercising if I experience even a little bit of discomfort.” Rationale: Mild discomfort is expected during joint activity. Exercise should be balanced-not avoided entirely. Rest is needed during flares, but gentle exercise is encouraged otherwise.
