Final answer:
The nurse will use a trochanter roll to prevent injury secondary to hip rotation in a patient with a spinal cord injury.
Step-by-step explanation:
To prevent injury secondary to hip rotation in a patient with a spinal cord injury, the nurse will use a trochanter roll. A trochanter roll is a cylindrical device placed between the trochanters, which are bony prominences on the upper portion of the femur. It helps to maintain proper alignment of the hips and prevents external rotation. This device is commonly used in patients who are immobilized or have limited mobility.
