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

system failure=4%
2 organ system failures=32%
3 organ system failures=67%
4 organ system failures=90%
What are the four collisions? -Correct Answer ✔1. The vehicle
2. The occupants
3. The internal organs
4. The secondary impacts
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
