A nurse is caring for a client who has been placed in halo traction to immobilize his cervical spine. Which of the following actions should the nurse take?

A. The client may be positioned supine, but the key action to prevent complications is not the supine position itself. B. A pelvic girdle is not typically used in halo traction; traction is maintained via the halo vest or pins. C. Elevating the head of the bed (usually 30–45 degrees) promotes respiratory function, reduces edema, and enhances comfort while maintaining cervical immobilization, making this the correct action. D. Elevating the foot of the bed does not contribute to the care or safety of a client in halo traction.
