Be run over by the vehicle as they are propelled to the ground.

28-Which of the following general statements regarding trauma is correct?

31-If the windshield of a wrecked vehicle is cracked or broken:

The front seat occupant has a cervical spine injury until proven otherwise.

37-Which of the following statements regarding gunshot wounds is correct?

The most important factor for the seriousness of a gunshot wound is the type of tissue through which the projectile passes.

5-Which of the following is NOT a factor when considering transport of a trauma patient via helicopter?

Upward.

4-If a Level I trauma center is 30 miles away, and a Level II trauma center is 10 miles away, it would be MOST appropriate to transport a patient with a severe traumatic brain injury:

Via air transport to the Level I trauma center.

32-When a patient takes the "up-and-over" pathway during a head-on collision:

3-A specific attribute of a Level I trauma center is that it:

Has 24-hour in-house coverage by general surgeons.

29-If the mechanism of injury does not appear to be significant, you should consider transporting an injured patient to a Level I trauma center if he or she:

Has a known bleeding disorder.
