The nurse is assisting with the care of a patient with rheumatoid arthritis (RA). The nurse must remember in which way RA care is different from osteoarthritis care. What type of nursing care does the nurse specifically provide for the patient with RA?

A. It's important to monitor all body systems for effects of the disease: RA is a systemic autoimmune condition affecting not just joints, but also the heart, lungs, eyes, skin, and more. B. Injury and age are the greatest contributors to disease development: This describes osteoarthritis, not RA. RA is autoimmune in origin. C. Acutely inflamed joints respond best to heat therapy: Cold therapy is best during acute flares to reduce inflammation; heat is more useful during chronic stiffness. D. Exercise is poorly tolerated and frequent rest is needed: Regular, low-impact exercise is encouraged in RA to prevent stiffness and muscle wasting. Rest is important, but not excessive.
