B) Children tend to be thrown onto the hood of the vehicle. C) Children tend to turn toward the vehicle. D) Adults tend to turn toward the vehicle. 12) Which of the following is most likely to be fractured from a fall onto outstretched hands? A) Carpals B) Metacarpals C) Clavicle D) Ulna 13) Your patient, a 23-year-old woman who is 6 months pregnant, was the unrestrained driver of a vehicle that rear-ended a parked car. The air bag deployed. Considering the likelihood of organ collision, for which of the following injuries should you maintain a high index of suspicion? A) Cardiac contusion B) Anterior flail segment C) Abruptio placentae D) Fractured sternum 14) Which of the following best describes why the occupants of a vehicle moving at 50 miles per hour will be injured when the vehicle strikes a tree but not when it brakes to a stop? A) Braking allows the kinetic energy to be absorbed evenly into the frame of the vehicle, rather than concentrating it at the point of impact. B) The energy gradually dissipates as heat due to the friction of braking, rather than transferring to the vehicle and its occupants. C) The inertia of the tree increases the kinetic energy transmitted to the occupants by a factor of 10. D) None of the above describes why. 15) In frontal impact collisions which pathway of patient travel results in higher mortality? A) Vertical B) Straight C) Up-and-over D) Down-and-under 16) Upon arriving at the scene of a single-vehicle collision in which the vehicle struck a utility pole, you note that the windshield is “spidered,” or “starred,” and that the driver was not restrained. Which of the following injuries is most likely? A) Whiplash injury of the neck muscles B) Compression injury of the cervical spine C) Distraction injury of the cervical spine D) Ligamentous neck injury due to rotation beyond the range of motion 17) Which of the following factors is NOT a consideration in the severity of injury related to falls? A) Landing surface B) Wind resistance C) The initial point of impact D) Distance of the fall 18) Which of the following is TRUE of motorcycle collisions? A) Frontal impact can result in intraabdominal, pelvic, and femur injuries. B) A rider who “lays down the bike” will generally receive more severe injuries than a rider who stays with the bike. C) The structural steel of the vehicle absorbs most of the kinetic energy in a motorcycle collision. D) The use of helmets has drastically reduced the incidence of cervical spine injuries. 19) In which of the following types of impact should you have a higher index of suspicion because the degree of injury may be greater than the damage alone indicates? A) Rear-end B) Oblique C) Lateral D) Frontal 20) Which of the following best defines the term energy? A) The ability to deform solid objects B) The rate of motion related to time C) The capacity to do work D) The amount of heat generated through friction
