Questions and Answers (100% Pass)
1.Kinetic energy is a calculation of:
A.weight and size.
B.weight and speed.
C.mass and weight.
D.speed and force. - ✔️✔️B.weight and speed.
Rationale: Kinetic energy is a calculation of mass (weight) and velocity (speed). Energy
cannot be destroyed, only converted. (1/2 mv^2)
Force is a product of mass * acceleration
2.A 20-year-old man has major open facial injuries after his vehicle struck a tree head-
on. Which of the following findings within the car would MOST likely explain his injury
pattern?
A.Deployed airbag

B.Bent steering wheel
C.Nonintact windshield
D.Crushed instrument panel - ✔️✔️C.Nonintact windshield
Rationale: The mechanism of injury and condition of the vehicle's interior suggest likely
areas of injury. Head and neck injuries are likely to result when the head and face
impact the windshield.
deployed airbags typically result in abrasions of the face, head, and arms // bent
steering wheel tyoically indicates the presence of chest injuries // crushed instrument
panel typically indictaes the presence of leg and hip injuries
3.Which of the following would MOST likely result from the third collision in the "three-
collision" effect that occurs during a high-speed, frontal impact motor vehicle crash?
A.Extensive damage to the automobile
B.Flail chest and lower extremity fractures
C.Massive external trauma with severe bleeding
D.Aortic rupture or compression injury to the brain - ✔️✔️D.Aortic rupture or compression
injury to the brain

Rationale: During the third collision, the body's internal organs collide with the inside of
the body. These injuries are usually not as obvious, but are often the most life-
threatening. Injuries that may result from this include internal injuries of the brain
(compression injuries) and aortic tears, resulting in massive internal bleeding.
A would occur in first collision (vehicle vs other object); B & C would occur in second
collision (person vs vehicle)
4.A young male experienced severe blunt chest trauma when his passenger car struck
another vehicle head-on. During your inspection of the interior of his vehicle, you would
MOST likely find:
A.deployed airbags.
B.steering wheel deformity.
C.starring of the windshield.
D.a crushed instrument panel. - ✔️✔️B.steering wheel deformity.
Rationale: Blunt chest injuries during a motor vehicle crash typically occur when the
chest impacts the steering wheel. Therefore, your inspection of the vehicle's interior will
most likely reveal a deformed steering wheel.

5.An unrestrained driver collided with a bridge pillar. Upon inspection of the interior of
his vehicle, you note that the lower dashboard is crushed. During your assessment of
the patient, you will MOST likely encounter:
A.trauma to the pelvis.
B.blunt abdominal trauma.
C.a severe closed head injury.
D.penetrating thoracic trauma. - ✔️✔️A.trauma to the pelvis.
Rationale: Impact points are often obvious from a quick inspection of the vehicle's
interior. During a frontal collision, the unrestrained occupant's knees often impact the
lower dashboard. With this type of impact, energy is transferred from the knees to the
femurs, and then to the pelvis or hip.
abdominal trauma comes from striking steering wheel; severe closed head injury comes
from striking windshield; penetarting thoracic trauma caused by flying debris, collisions
w parts of vehicle, or other movable objects
6.Whiplash injuries are MOST common following _________ impacts.
A.rear-end
B.rollover
