To prevent musculoskeletal injury while repositioning a client with quadriplegia, the nurse should do which of the following?

Internally rotating the client's hips by using a trochanter roll is important in preventing musculoskeletal injury while repositioning a client with quadriplegia. This technique helps maintain proper alignment of the hips and prevents external rotation, which can lead to complications such as joint dislocation or contractures.

Using a trochanter roll provides stable support to the hip joint and keeps the legs in a neutral position. This minimization of unwanted movement is critical for clients with quadriplegia, who may not have the ability to reposition themselves, thus decreasing the risk of injury to both the client and the caregiver.

Maintaining proper positioning of the hips and legs helps support the overall body alignment and reduces strain on the musculoskeletal system during repositioning tasks, ensuring safer handling for both the nurse and the client.
