1) Which of the following statements about low-velocity penetrating trauma is TRUE? A) Shorter knives and ice picks may be removed if they are left in the wound. B) There is no pressure shock wave with a knife wound as there is with an arrow wound. C) More injuries are sustained from arrows than from knives. D) Knives, arrows, ice picks, and similar weapons cause damage only in their direct path. 2) Your patient is an eight-year-old male with a pencil impaled 2 centimeters inferior to the xiphoid process. You note that the pencil is pulsating. Which of the following is the best action? A) Start an IV and request orders for analgesia and sedation. B) Remove the pencil and apply direct pressure to the wound; transport to a trauma center if the bleeding does not stop with direct pressure. C) Stabilize the pencil in place and transport to a trauma center. D) Stabilize the pencil and transport to the nearest medical facility. 3) The pathway of injury left in the wake of a penetrating mechanism of injury is called: A) Cone of injury B) Cavitation C) Profile D) Trajectory 4) The passage through tissue of a high-energy bullet creates a temporary cavity and a permanent cavity. Which of the following statements is TRUE of the permanent cavity created by penetrating trauma? A) It is filled with disrupted tissues, some air, fluid, and debris. B) It is the damage done when the projectile fragments penetrate. C) It is a space created by a projectile as tissue moves rapidly away in its path. D) It is a potential space, not an actual space. 5) Which of the following is TRUE of the pressure wave that accompanies high-velocity penetrating trauma? A) Hollow organs are less tolerant of the stress than solid organs are. B) Pressure waves cause no injury to surrounding tissues; they only momentarily disrupt function. C) Elastic tissues are less tolerant of the stress than nonelastic tissues. D) The pressure wave may be transmitted through blood, resulting in damage to blood vessels some distance from the primary wound. 6) Your patient is a 50-year-old male with a gunshot wound to the right anterior chest. He is unresponsive. Which of the following should you do first? A) Check for a carotid pulse. B) Seal the chest wound. C) Auscultate breath sounds. D) Check for breathing. 7) Your patient is a 30-year-old female with a stab wound to the neck. She is sitting up and appears very anxious and short of breath. There is minimal external bleeding noted, but there is bubbling from the wound. Which of the following should you suspect, based on the mechanism of injury and assessment findings? A) Laceration of the trachea B) An injury to the spinal cord at the level of the stab wound C) Laceration of the ipsilateral carotid artery D) All of the above 8) If you were to design a bullet to have the highest energy exchange, what would you do? A) Decrease the drag B) Increase the caliber C) Decrease the bullet’s trajectory D) Design the bullet to become more unstable 9) Which of the following is most important when assessing the damage done by a gunshot? A) The type of gun used B) The size of the bullet C) The distance from the shooter D) Whether there was an upward or a downward trajectory when the bullet was fired 10) A penetrating injury to which of the following organs is LEAST likely to result in severe hemorrhage?
