Correct Answer is A

Explanation

A halo device is a type of external fixation device that immobilizes the cervical spine after an injury or surgery. The device consists of a metal ring attached to four metal rods that are secured to a vest worn by the client. The device limits the movement of the head and neck, which can impair the client's ability to drive safely. The nurse should clarify with the provider if the client can operate a motor vehicle while wearing the halo device, as this may pose a risk for injury to the client and others on the road.

Placing a small pillow under the head when sleeping, increasing intake of fiber-rich foods, and taking tub baths instead of showers are all appropriate instructions for a client with a halo device
