After assessing ABCs in a client with a head injury, what should the nurse do next?

Following the assessment of the ABCs (Airway, Breathing, Circulation) in a client with a head injury, the next critical step is to immobilize the cervical spine. This is essential because head injuries often coincide with potential spinal injuries, particularly in cases of trauma. Stabilization is important to prevent any movement that could exacerbate a spinal cord injury or compromise neural function.

By immobilizing the cervical spine, the nurse ensures that the client's head and neck are kept in a fixed position, minimizing the risk of further injury while more comprehensive assessments and interventions are conducted. This is a priority in trauma care, as safeguarding the injury site is crucial to mitigate complications and allow for better management of the patient's overall condition.

Subsequent assessments, such as a neurological evaluation or interventions like administering pain medication, should be conducted after ensuring spinal stability. These steps can help in providing optimal care but would not take precedence over immobilization to protect against further injury.
