WEST COAST EMT BLOCK 4 REVIEW WITH 180 COMPLETE QUESTIONS AND ACCURATE ANSWERS WITH DETAILED RATIONALES RATED A+ 1. When applying a tourniquet to an amputated arm, the EMT should: A.use the narrowest bandage possible. B.avoid applying the tourniquet over a joint. C.cover the tourniquet with a sterile bandage. D.use rope to ensure that the tourniquet is tight. Correct Answer B.avoid applying the tourniquet over a joint. Rationale: If you must apply a tourniquet, never apply it directly over a joint. You should use the widest bandage possible and make sure it is secured tightly. Never use wire, rope, a belt, or any other narrow material, as it could cut the skin. The tourn iquet should never be covered with a bandage. Leave it open and in full view. 2. 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 Correct Answer 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 b rain (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) 3. 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 Correct Answer 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 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. Correct Answer 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. Correct Answer 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 C.frontal D.lateral Correct Answer A.rear -end Rationale: Whiplash injuries of the neck are a common occurrence following rear -end collisions. As the vehicle is suddenly thrust forward, the occupant's head is thrust backward. Properly positioned headrests can minimize the severity of whiplash injuries. rollover typically causes LT injuries; frontal causes chest, head, abd, extremity injuries; lateral should suspect lateral chest and abd injuries and pelvic injuries 7.Death from a rollover motor vehicle crash is MOST often secondary to: A.crushing injuries. B.airbag -related trauma. C.multiple collisions to the interior of the car. D.ejection of the patient from the motor vehicle. Correct Answer D.ejection of the patient from the motor vehicle. Rationale: Rollover crashes are the most unpredictable with regard to injuries sustained by the patient. An unrestrained passenger may have struck multiple points within the vehicle. However, the most life -threatening event in a rollover is ejection or par tial ejection of the patient from the vehicle. crushing injuries occu during ejection or partial ejections; airbag trauma significantly reduces death; multiple collisions w interior of car makes prediction of injury patterns difficult, but is not the most LT event 8.Severe abrasion injuries can occur when motorcycle riders are slowed after a collision by road drag. Road drag is most often associated with which type of motorcycle impact? A.Head -on collision B.Angular collision C.Ejection D.Controlled crash Correct Answer C.Ejection
