A nurse is caring for a 25-year-old male quadriplegic client. Which of the following treatments would the nurse perform to decrease the risk of joint contracture and promote joint mobility?

The correct answer is to provide passive range of motion (ROM). In quadriplegic clients, who have limited or no movement of their limbs, passive ROM exercises are crucial to maintain joint mobility and prevent joint contractures. Administering glucosamine supplements (choice A) is not directly related to promoting joint mobility. Turning the client every 2 hours (choice B) is essential for preventing pressure ulcers but does not directly address joint contracture and mobility. Providing active ROM exercises (choice C) may not be suitable for quadriplegic clients as they are unable to perform these movements on their own.
