Which of the following actions can help nurses decrease the risk for contractures in clients?

A. Range of motion exercises maintain joint mobility by preventing the shortening and hardening of muscles, tendons, and ligaments. These movements stimulate the production of synovial fluid, which lubricates the joint capsule and preserves the elasticity of connective tissues. Consistent implementation of these exercises is the primary clinical intervention used to prevent permanent musculoskeletal deformities. B. Completing all basic care for the client promotes a state of passivity and may lead to functional decline and muscle atrophy. Nurses should instead encourage the client to participate in self-care to maintain muscle tone and joint flexibility through active movement. Over-assisting a client removes the natural opportunities for physical activity that are essential for preventing secondary complications. C. Encouraging prolonged sitting in one position is a direct risk factor for the development of contractures, particularly in the hips and knees. Static positioning allows muscles to remain in a shortened state, leading to adaptive changes in tissue length and a restricted range of motion. Frequent repositioning is necessary to ensure that various muscle groups are periodically lengthened and loaded. D. While elevating the head of the bed may assist with respiratory excursion or prevent aspiration, it does not specifically address the prevention of joint contractures. In fact, keeping the head of the bed elevated for extended periods can contribute to hip flexion contractures if the client's position is not varied. It is a targeted respiratory intervention rather than a musculoskeletal one.
