A nurse's plan of care for a patient with rheumatoid arthritis includes several exercise-based interventions. Exercises for patients with rheumatoid disorders should have which of the following goals?

Choice A reason: Maximizing range of motion is a valid therapeutic goal; however, minimizing exertion is not entirely accurate for rehabilitative purposes. While rest is essential during acute inflammatory flares, complete avoidance of exertion can lead to muscle atrophy and further joint instability, which complicates the clinical progression of rheumatoid arthritis. Choice B reason: Increasing joint size is a pathological sign of inflammation, effusion, or bony overgrowth rather than a therapeutic goal. Strength training is beneficial, but the primary focus in rheumatoid disorders remains functional mobility and the stabilization of the joint capsule rather than hypertrophy of the surrounding soft tissue structures. Choice C reason: Limiting energy output is necessary during systemic exacerbations of rheumatoid arthritis to manage fatigue. However, this is a passive strategy rather than an exercise-based goal. Exercise must be designed to maintain functional capacity rather than solely preserving strength for healing, which is a poorly defined physiological outcome. Choice D reason: The primary therapeutic objective is to maintain or improve joint flexibility while avoiding mechanical trauma to the synovial membranes and articular cartilage. Low-impact, isometric, or aquatic exercises are prioritized to enhance synovial fluid circulation and prevent fibrous ankylosis without exacerbating the existing autoimmune-mediated joint destruction.
