#1
Which of the following is a common mechanism of injury in high-speed motor vehicle collisions?
Whiplash injury
ExplanationRapid acceleration followed by sudden deceleration causing neck strain.
#2
Which of the following describes the concept of 'kinematics' in the context of impact events?
The study of how forces affect the motion of bodies
ExplanationUnderstanding movement and its relationship with forces in collisions.
#3
Which of the following is a primary concern in the management of trauma patients involved in impact events?
Airway obstruction
ExplanationEnsuring the patient's airway remains unobstructed to facilitate breathing.
#4
What is the term for the phenomenon where a person's organs continue moving inside the body after an external impact has occurred?
Coup-contrecoup injury
ExplanationInertia causing internal organs to move and impact opposite sides.
#5
Which of the following factors can influence the severity of trauma in an impact event?
Vehicle speed
ExplanationFaster vehicle speed increases injury severity.
#6
Which of the following factors determines the severity of trauma in an impact event?
Velocity of the impact
ExplanationSpeed at which the collision occurs influences injury severity.
#7
In an impact event, what does the 'golden hour' refer to?
The first 60 minutes after the collision, during which medical treatment is most effective
ExplanationCritical period immediately after impact for effective medical intervention.
#8
Which of the following is a common injury pattern associated with pedestrian impacts?
Lower extremity fractures

#9
What term is used to describe the process of removing an individual from a wrecked vehicle following an impact event?
Extrication
ExplanationRescuing individuals trapped in vehicles post-collision.
#10
Which of the following is a common injury associated with rapid deceleration in impact events?
Whiplash injury
ExplanationNeck strain due to sudden stoppage of movement.
#11
Which of the following injuries is often associated with high-speed deceleration during an impact event?
Brain contusion
ExplanationBrain tissue damage due to sudden stoppage of movement.
#12
Which of the following statements regarding the 'secondary collision' in impact events is accurate?
It occurs when debris from the initial collision strikes nearby objects.
ExplanationAdditional impacts caused by debris from the primary collision.
#13
Which of the following factors can affect the likelihood of ejection from a vehicle during an impact event?
Seat belt usage
ExplanationWearing seat belts reduces the risk of being thrown from the vehicle.
#14
Which of the following factors can influence the likelihood of sustaining a head injury in an impact event?
Use of protective headgear
ExplanationWearing head protection reduces the risk of head injury.
#15
Which of the following factors can affect the risk of injury for occupants involved in a rollover event?
Vehicle's center of gravity
ExplanationHigher center of gravity increases risk of rollover and injury.
