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
,Incidence of trauma peaks at what age? - CORRECT ANSWER Teens and young adult
Blunt trauma Classifications include? - CORRECT ANSWER MVA
Auto vs. pedestrian
Falls
Struck by or against an object
Trauma mortality based on organ system failure? - CORRECT ANSWER 1 organ
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
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
Factors predicting fall injuries are? - CORRECT ANSWER Fall height (velocity)
Landing surface (deceleration distance)
Point of impact on the body
Wound ballistics- permanent cavity - CORRECT ANSWER Cavity is the a function of
the size, shape, and characteristic of the missile (mass)
For every second of fall time, speed increases by? - CORRECT ANSWER Speed
increases by approximately 20 MPH
Define Shock? - CORRECT ANSWER A state in which cellular oxygen demand
exceeds supply
When the cost of tissue oxygen is higher than the body can pay, an oxygen debt develops.
Types of shock per TCAR? - CORRECT ANSWER Pumps-Site of defect heart
Pipes- site of defect is artery, veins or capillaries
Fluid-intravascular, interstitial or intracellular
VS in shock? - CORRECT ANSWER Narrow pulse pressure
Tachycardia
Low CO

ANSWER 32 ATP molecules
How many ATP molecules are produced without oxygen? - CORRECT ANSWER 2
ATP molecules
