A nurse is planning care for a client who has rheumatoid arthritis. Which of the following referrals should the nurse recommend?

A. Dietitian: While nutrition can play a role in overall health and inflammation management, a dietitian referral is not the primary intervention for rheumatoid arthritis. Dietary counseling may be considered adjunctively but is not central to preserving joint function. B. Case manager: A case manager helps coordinate care and resources, which may be helpful for complex cases, but referral is not specifically targeted to managing the functional impairments associated with rheumatoid arthritis. C. Podiatrist: A podiatrist is consulted if the client develops foot or ankle complications. Routine referral is not indicated unless specific joint issues are present in the lower extremities. D. Physical therapist: Physical therapy is essential in rheumatoid arthritis care to maintain joint mobility, reduce pain, and prevent deformities. A physical therapist develops individualized exercise programs, educates on joint protection, and supports functional independence, making this referral highly appropriate.
