A client involved in a high-speed motor vehicle accident is transported to the emergency department by ambulance with immobilization devices in place for high probability of a spinal cord injury and cervical spine fracture. What is the priority nursing action for this client?

Clients with suspected spinal cord injury and cervical spine fracture require rapid assessment using trauma priorities based on the ABCs—airway, breathing, and circulation. Cervical spine injuries can impair the muscles responsible for breathing and place the client at immediate risk for airway obstruction and respiratory failure. Immobilization must be maintained while ensuring adequate oxygenation and ventilation. Airway protection always takes priority over neurological or secondary assessments because hypoxia can rapidly become fatal. A. Observing for intra-abdominal bleeding and hemorrhage is important in high-speed trauma because multiple injuries may be present, but it is not the first priority. According to trauma assessment principles, airway and breathing must be stabilized before evaluating secondary injuries. Internal bleeding is serious, but immediate respiratory compromise takes precedence over abdominal assessment. B. Assessing for loss of motor function and sensation helps determine the extent of spinal cord injury and neurological impairment. However, neurological assessment is performed after ensuring the client has a patent airway and stable breathing. Without adequate oxygenation, neurological status can worsen rapidly, making airway management the first concern. C. Obtaining a 12-lead electrocardiogram may be useful later if cardiac injury or dysrhythmia is suspected, but it is not the immediate priority in a suspected cervical spine trauma patient. Cardiac monitoring follows stabilization of airway and breathing. Life-saving interventions are prioritized before diagnostic testing. D. Assessing respiratory pattern and airway patency is the highest priority because cervical spinal cord injuries, especially at higher levels, can impair diaphragmatic function and cause respiratory arrest. Maintaining spinal immobilization while evaluating airway ensures both neurologic protection and oxygen delivery. Immediate identification of airway compromise prevents hypoxia and supports survival in the acute trauma setting.
