Final answer:
A significant trauma to the face should increase the AEMT's index of suspicion for a basilar skull fracture, which can be life-threatening due to potential bleeding and increasing pressure on the brain.
Step-by-step explanation:
The answer to the question is b
A significant trauma to the face should increase the EMT's index of suspicion for a basilar skull fracture. A basilar skull fracture is a fracture at the base of the skull which can be life-threatening because it can damage the artery that passes through the carotid canal, leading to bleeding inside the skull. If left untreated, the accumulation of blood can exert increasing pressure on the brain and result in death within a few hours.
