TNCC 8TH EDITION EXAM

is equal to 1/2 the mass multiplied the square of its velocity therefore when mass is doubled so is the net energy, however, when velocity is doubled energy is quadrupled. 4. What is tension? stretching force by pulling at opposite ends 5. What is compression? Crushing by squeezing together 6. What is bending? Loading about an axis.Bending causes compression on the side the person is bending toward intention to the opposite side 7. What is shearing? Damage by tearing or bending by exerting faucet different parts in opposite directions at the same time. 8. What is torsion? Torsion forces twist ends in opposite directions. 9. What is combined loading? Any combination of tension compression torsion bending and/or shear. 10. Blunt, penetrating, thermal, or blast. TNCC 8th Edition 2 / 9 What are the four types of trauma related injuries? 11. What are contributing factors to injuries related to blunt traumas? 12. What are the seven patterns of pathway injuries related to motor vehicle accidents? 13. Differentiate between the three impacts of motor vehicle impact sequence. 14. What are the three factors that contribute to the damage caused by penetrating trauma's? 15. What causes the primary effects of blast traumas? 16. What causes the secondary effects of blast traumas? 17.17. The point of impact on the patient's body, the type of surface that is hit, the tissues ability to resist (bone versus soft tissue, air-filled versus solid organs), and the trajectory of force. Up and over, down and under, lateral, rotational, rear, roll over, and ejection. The first impact occurs when the vehicle collided with another object. The second impact
