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
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
How many ATP molecules are produced with oxygen & glucose? - CORRECT
ANSWER - 32 ATP molecules
How many ATP molecules are produced without oxygen? - CORRECT
ANSWER - 2 ATP molecules
Normal pH? - CORRECT ANSWER - Refernce range is 7.35-7.45, but actual
normal range is 7.38-7.42
What is the footprint of shock? - CORRECT ANSWER - Lactic Acidosis
