A patient ejected from a vehicle has closed deformities to both femurs and is unresponsive. You should:

For this scenario, the only appropriate choice is to stabilize the patient's head and perform a primary assessment. This approach is crucial because the patient has been ejected from a vehicle, indicating a high-velocity trauma that likely involves significant risk for spinal injuries and other life-threatening conditions.

Stabilizing the head is important to prevent any further spinal cord injury, as movement of the head and neck can exacerbate potential damage. Conducting a primary assessment is vital for identifying immediate threats to life, such as airway compromise, breathing difficulties, and circulatory status. This assessment helps in determining the necessary interventions to stabilize the patient’s condition before any further treatment.

While administering oxygen and performing a rapid assessment would generally be part of the emergency response, in this particular case, focusing on spinal stabilization and a thorough primary assessment takes precedence given the unresponsiveness and mechanism of injury. Applying stabilization directly to the femurs is inappropriate at this stage, as addressing potential life-threatening issues like airway and cervical spine stability is more critical. Assessing for a carotid pulse and assisting with ventilations becomes part of the management of respiratory or circulatory failure but comes after ensuring that the patient is appropriately stabilized and assessed for other immediate needs.
