You respond to a construction site where a steel girder collapsed on a 22 year old male's chest. Coworkers removed the girder prior to your arrival. Your assessment reveals that he is unconscious and apneic, but has a pulse. You should:
a. maintain stabilization of his head, open his airway with the jaw thrust maneuver, and ventilate with a bag mask device
b. open his airway with the jaw thrust maneuver, maintain his head in a neutral in-line position and insert a combitube
c. apply a cervical collar, maintain an open airway with the jaw thrust maneuver, and wait for ALS prior to beginning ventilation
d. not consider an airway adjunct due to the patient's trauma presentation
