B. Pulmonary contusion
C. Hypovolemia
D. Small pneumothorax
E. Flail chest
B. Pulmonary contusion

B. Will exclude cervical spine injury if no abnormalities are found on the x-rays
C. Are not needed if she is awake, alert, neurologically normal, and has no neck pain or midline tenderness
D. Should be performed before adressing potential breating or circulatory problems
E. May show atlanto-occipital dislocation if the Powers ratio is <1 --> 1:noraml, >1 anterior, <1 posterior
C. Are not needed if she is awake, alert, neurologically normal, and has no neck pain or midline tenderness
