If a 7-year-old boy is unresponsive and bleeding after being struck by a car, what should you do first?

In this scenario, opening the airway and suctioning is essential because the child is unresponsive. When dealing with an unresponsive patient, it's crucial to ensure that the airway is clear to facilitate effective oxygenation and ventilation. An unresponsive individual is at significant risk of airway obstruction, particularly due to the potential accumulation of blood or vomit, which can compromise breathing.

By opening the airway first, you create an opportunity for adequate ventilation, which is vital for the survival of the child. Suctioning may be necessary to remove any blood or obstructive material from the airway, thereby preventing asphyxiation.

Other interventions, such as checking for a pulse, applying direct pressure to control bleeding, or starting CPR, are essential as well but come after ensuring that the airway is patent. In cases of trauma and unresponsiveness, managing the airway takes precedence to promote the best possible chance for the patient's recovery.
