A patient is brought to the emergency department with injuries sustained when a wall collapsed in the home. The nurse recognizes that this patient's injuries were most likely caused by which mechanism of injury?
1. crushing
2. shearing
3. deceleration
4. blast
Correct Answer: 1
A crushing injury occurs from a high force that leads to tissue destruction. The collapsing wall most likely caused crushing injuries. Shearing occurs when structures slip across each other. Deceleration is the decrease in speed of a moving object. Blast injuries result from the temperature and velocity of air movement and the force of projectiles from the explosion.
