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.

steering wheel tyoically indicates the presence of chest injuries // crushed instrument

panel typically indictaes the presence of leg and hip injuries

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.

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
