TCAR CERTIFICATION EVALUATION
SCRIPT FULL SOLUTION GRADED A+
●● How are closed mid-shaft femur fractures managed?
Answer: Intramedullary nail fixation
●● What makes a fracture comminuted?
Answer: The bone is in multiple pieces
●● Physiologic criteria for trauma center care?
Answer: SBP<90
Resp rate <10 or >29
GCS <14
●● What is Kinematics?
Answer: The process of predicting potential injuries based on analysis of
the forces involved
●● Dose of energy is?
Answer: The nature and amount of force
●● Characteristic of wounding agent?
,Answer: Type of energy and how it was applied
●● Force
Answer: The dose of energy involved
●● Which gender is the majority of trauma?
Answer: Male
●● Incidence of trauma peaks at what age?
Answer: Teens and young adult
●● Blunt trauma Classifications include?
Answer: MVA
Auto vs. pedestrian
Falls
Struck by or against an object
●● Trauma mortality based on organ system failure?
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?
Answer: 1. The vehicle
2. The occupants
3. The internal organs
4. The secondary impacts
●● Energy transmission in a rollover depends on?
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?
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?
Answer: Falls
, ●● Factors predicting fall injuries are?
Answer: Fall height (velocity)
Landing surface (deceleration distance)
Point of impact on the body
●● Wound ballistics- permanent cavity
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?
Answer: Speed increases by approximately 20 MPH
●● Define Shock?
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?
Answer: Pumps-Site of defect heart
Pipes- site of defect is artery, veins or capillaries
Fluid-intravascular, interstitial or intracellular
●● VS in shock?
