When caring for a client with a cervical spinal cord injury, which intervention is the most important for the nurse to implement?

A. Logroll to change positions: Logrolling is important to maintain spinal alignment and prevent further injury, but it is a supportive measure used during repositioning. It is not the immediate priority compared to stabilizing the cervical spine continuously. B. Obtain hourly neurological assessments: Frequent neurological checks are essential to monitor for deterioration, but they do not prevent further spinal cord damage. Stabilization must come first to reduce the risk of worsening neurological deficits. C. Immobilize the head in anatomical alignment: Maintaining strict immobilization of the cervical spine is the most important intervention. This prevents additional spinal cord compression or injury, which could result in paralysis or loss of function. D. Assess the extremity reflexes: Reflex testing provides baseline neurological information, but it does not address the immediate risk of spinal instability. It is a lower priority compared to immobilizing the cervical spine to preserve function.
