During your assessment of a 79-year-old woman who was involved in a motor vehicle crash, you find that she is responsive to pain only and is breathing with a marked reduction in tidal volume. Your rapid assessment reveals that she has ecchymosis and crepitus over several of her ribs. You should:
A) avoid any form of positive-pressure ventilation, as this may cause barotrauma and a pneumothorax.
B) stabilize her fractured ribs with bulky dressings and administer high-flow oxygen via nonrebreathing mask.
C) immediately secure her airway with an endotracheal tube because she is at increased risk for aspiration.
D) assist her ventilations with a bag-mask device, delivering just enough volume to produce visible chest rise.
