Then answer the questions that follow. Your unit responds to a 911 call from a mother who reports that her 7-year-old son “has fallen from his tree house.” When you arrive on the scene, the mother leads you into the backyard, where you see the boy grimacing in pain. He is holding his right leg. As you approach, he tells you that “it hurts all the way down to my toes.” You introduce yourself and learn that the patient’s name is Roger. Roger tells you that he was climbing into the tree house and fell off the ladder. You ask Roger if he remembers how he landed. “I think I landed on my feet first,” he says. “It hurt so much that I couldn’t stand up.” 1. Explain the mechanism of injury associated with Roger’s injuries. 2. Which bones or joints do you suspect have been injured? 3. Which type of splint will you use to immobilize Roger’s injured leg? Why? 4. What are four basic questions that should be asked of this patient? CHAPTER 30 REVIEW Write the word or words that best complete each sentence in the space provided. 1. The system is composed of all the bones, joints, and muscles of the body. 2. As components of the skeleton, bones provide the body’s 3. . are the places where bones meet and are a critical element in the body’s ability to move. 4. A common type of bone injury is a break, or . 5. With __________________ _________________, the force impacts one end of the limb, causing injury some distance away from the point of impact. 6. are bands of connective tissue that bind the muscles to the bones. 7. Three types of mechanisms that cause musculoskeletal injuries include force, force, and force. 8. The splint applies constant pull along the length of the femur to stabilize fractures and reduce muscle spasms. 9. The EMT should splint suspected dislocations in position unless are absent. 10. Proper and prehospital care of musculoskeletal injuries can help prevent closed injuries from becoming 11. injuries. If the patient’s thigh is painful, swollen, or deformed, the EMT should treat the patient as if the is fractured. 12. To splint an injured extremity, an EMT must assess _____________, , and before and after splinting. 13. Dramatic-looking or painful extremity injuries can sometimes distract an untrained person from looking for other - conditions.
