A nurse is caring for a child who is in a halo vest for cervical traction. Which of the following actions should the nurse take?

A. Show the child's parent how to release tension on the bars: The tension on the halo vest is adjusted by the healthcare provider, not by the parent. The nurse should not instruct the parent to release tension, as improper adjustments can lead to complications. B. Remove the vest for the child to sleep at night: The halo vest should remain in place at all times, including during sleep, to maintain proper cervical traction and stabilization. Removing it may interfere with the healing process and cause further injury. C. Check the child's pupillary response: Monitoring the pupillary response is important in a child with cervical traction to assess for any neurological changes. It helps identify signs of increased intracranial pressure or other neurological complications. D. Apply a cervical collar if the child reports neck pain: The halo vest itself is designed to stabilize the neck, and the application of a cervical collar without provider guidance could interfere with the proper use of the traction system.
