Injury caused by objects that pierce the surface of the body |
Penetrating trauma |
|
How trauma occurs |
Mechanism of (MOI) |
|
Significant MOI that causes injuries to more than one body system |
Multisystem trauma |
|
Result of force to the body that causes injury but does not pierce soft tissue or internal organs and cavities |
Blunt trauma |
|
Product of mass, gravity, and height |
Potential energy |
|
Force acting over a distance |
Work |
|
Energy of a moving object |
Kinetic energy |
|
Emanation of pressure waves that can damage nearby structures |
Cavitation |
|
A fall from more than _____ times the patient’s height is considered to be significant. |
three |
|
A patient complaining of chest tightness, coughing up blood, and subcutaneous emphysema following an explosion may be suffering from a: |
pulmonary blast injury |
|
A young boy was riding his bicycle down the street when he hit a parked car. What was the second collision? |
The bike rider hitting his bike or the car |
|
Awareness of and concern for potentially serious obvious and underlying injuries is referred to as the: |
index of suspicion. |
|
Significant clues to the possibility of severe injuries in motor vehicle collisions include: |
death of a passenger |
|
Which of the following is considered a type of motor vehicle collision? |
Rollover |
|
A driver involved in a rollover motor vehicle crash will MOST likely experience serious injuries or death if he or she: |
is ejected or partially ejected. |
|
Air bags are designed to: |
decrease the severity of deceleration injuries. |
|
By what mechanism is a person injured when he or she falls from a significant height? |
Potential energy is converted to kinetic energy; the kinetic energy is then converted into the work of bringing the body to a stop. |
|
If one or more occupants in the same vehicle are killed in a crash, the EMT should: |
suspect that all living occupants experienced the same serious trauma. |
|
Signs of a pulmonary blast injury include: |
coughing up blood. |
|
The cervical spine is MOST protected from whiplash-type injuries when the: |
headrest is appropriately positioned. |
|
The phenomenon of pressure waves emanating from the bullet, causing damage remote from its path, is known as: |
cavitation. |
|
When a motor vehicle strikes a tree while traveling at 40 mph, the unrestrained occupant: |
remains in motion until acted upon by an external force. |
|
When caring for an occupant inside a motor vehicle equipped with an air bag that did not deploy upon impact, you should: |
remember that it could still deploy and seriously injure you. |
|
Which of the following would MOST likely occur as the direct result of the second collision in a motor vehicle crash? |
Deformed steering wheel |
|
arterial air embolism |
Air bubbles in the arterial blood vessels. |
|
Coup contrecoup brain Injury |
A brain injury that occurs when force is applied to the head and transmission through brain tissue causes injury on the opposite side of original impact |
|
tympanic membrane |
The eardrum |
|
