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?

Awareness of and concern for potentially serious obvious and underlying injuries is referred to as the:

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
