Energy transmission in a rollover depends on? - CORRECT ANSWER-
Deceleration distance
Energy is dissipated over the distance of the roll and whether or not the
occupants are restrained
Car vs pedestrian injuries depend on? - CORRECT ANSWER-Point of contact
with the care
Height of hood & bumper
Size & weight of vehicle
Height of patient
Direction patient was facing when struck
,What is the most common mechanism of injury in all age groups? - CORRECT
ANSWER-Falls
What are the definitive options for pelvic fracture stabilization and hemorrhage
control? - CORRECT ANSWER-External Fixation
Interventional Radiology
Open reduction & Internal fixation
How are closed mid-shaft femur fractures managed? - CORRECT ANSWER-
Intramedullary nail fixation
What makes a fracture comminuted? - CORRECT ANSWER-The bone is in
multiple pieces
Physiologic criteria for trauma center care? - CORRECT ANSWER-SBP<90
Resp rate <10 or >29
GCS <14
What is Kinematics? - CORRECT ANSWER-The process of predicting potential
injuries based on analysis of the forces involved
,Dose of energy is? - CORRECT ANSWER-The nature and amount of force
Characteristic of wounding agent? - CORRECT ANSWER-Type of energy and
how it was applied
Force - CORRECT ANSWER-The dose of energy involved
Which gender is the majority of trauma? - CORRECT ANSWER-Male

adult
Blunt trauma Classifications include? - CORRECT ANSWER-MVA
Auto vs. pedestrian
Falls
Struck by or against an object

system failure=4%
, 2 organ system failures=32%
3 organ system failures=67%
4 organ system failures=90%
Factors predicting fall injuries are? - CORRECT ANSWER-Fall height (velocity)
Landing surface (deceleration distance)
Point of impact on the body
