SECTION 1: KINEMATICS & MECHANISM OF INJURY (Questions 1-
20)
QUESTION 1
What is the first question to ask in any traumatic injury?
A. What is the patient's GCS?
B. What was the dose of energy involved (high or low)?
C. Did the patient lose consciousness?
D. What is the patient's blood pressure?
Correct Answer: B. What was the dose of energy involved (high or low)?
*Rationale: * The dose of energy predicts injury patterns and guides assessment. High-
energy mechanisms (falls >20 ft, high-speed MVCs) cause more severe injuries.
Understanding the mechanism of injury is the foundation of trauma assessment and
allows the provider to anticipate potential injuries before they become clinically
apparent .
,QUESTION 2
What does "kinematics" refer to in trauma assessment?
A. The patient's lab values
B. The process of predicting potential injuries based on analysis of forces involved
C. The surgical treatment plan
D. The patient's past medical history
Correct Answer: B. The process of predicting potential injuries based on analysis of
forces involved
*Rationale: * Kinematics analyzes the mechanism of injury to predict which injuries are
likely. By understanding the forces applied to the body during trauma, the provider can
anticipate injury patterns and guide the secondary survey. This is a fundamental concept
in trauma care .
QUESTION 3
Car vs. pedestrian injuries depend on which factors? (Select all that apply)
A. Point of contact with the car
B. Height of hood and bumper
C. Increasing deceleration speed
D. Adding deceleration distance
,Correct Answer: A, B, and C
*Rationale: * Car vs. pedestrian injuries depend on the point of contact with the car, the
height of the hood and bumper, and increasing deceleration speed. These factors
determine the injury pattern: the bumper typically strikes the legs, the hood strikes the
torso, and the windshield/roof strikes the head. Adding deceleration distance (D)
reduces injury severity (helmets/airbags work this way) .
QUESTION 4
What is the #1 mechanism of injury across all age groups?
A. Motor vehicle crashes
B. Falls
C. Penetrating injuries
D. Blunt force trauma
Correct Answer: B. Falls
*Rationale: * Falls are the #1 mechanism across all age groups, from pediatric to
geriatric. In older adults, falls are a leading cause of traumatic injury and death. In
children, falls from playground equipment and windows are common. Understanding
the height and surface of the fall is critical for injury prediction .
, QUESTION 5
For every second of fall time, speed increases by approximately:
A. 10 MPH
B. 20 MPH
C. 30 MPH
D. 5 MPH
Correct Answer: B. 20 MPH
*Rationale: * Speed increases approximately 20 MPH per second of fall time, which
determines injury severity. This is a key concept in understanding the "dose of energy"
in fall injuries. A fall from 20 feet creates significant velocity and energy .
QUESTION 6
What factors predict injury severity in a fall? (Select all that apply)
A. Fall height (velocity)
B. Landing surface (deceleration distance)
C. Point of impact on the body
D. Time of day
Correct Answer: A, B, and C
