trauma

maximum time spent at a scene for a trauma patient.

An object increases its kinetic energy more by:
Definition
increasing its velocity than by increasing its mass
Term
the greatest amount of kinetic energy would be created if a ___ - pound driver struck a treat while traveling at ___ mph
Definition
140; 50
Term
The law of conservation of energy states that:
Definition
energy can be neither created nor destroyed: it can only change form
Term
Sudden deceleration of a motor vehicle that is traveling at 60 mph
Definition
dissipates tremendous forces and causes major injuries
Term
Which of the following injury mechanisms would MOST likely result in blunt trauma?
Definition
The pressure wave caused by a blast
Term
Penetrating trauma occurs when:
Definition
tissues are penetrated by single or multiple objects
Term
During abrupt deceleration:
Definition
shearing or rupturing of internal organs can occur
Term
Unlike deceleration injuries, crush & compression injuries occur:
Definition
at the time of impact
Term
The MOST common site of deceleration injury in the chest is the:
Definition
aorta
Term
The third phase of a motor vehicle accident involves:
Definition
deceleration of internal organs
Term
If the windshield of a wrecked vehicle is cracked or broken:
Definition
the front seat occupant has a cervical spine injury until proven otherwise
Term
The MOST reliable indicator that significant energy was dissipated by braking before a motor vehicle collision is:
Definition
the presence of tire skid marks at the scene
Term
The forces applied to the driver during a frontal vehicle collision will differ based on all of the following factors, EXCEPT:
Definition
the physical size of the patient
Term
The initial point of the bodily impact when an unrestrained passenger takes the "down and under" pathway during a frontal collision is the:
Definition
knees
Term
When a patient takes the "up and over" pathway during a head-on collision:
Definition
the anterior part of the neck may strike the steering wheel, resulting in a fractured larynx
Term
During the frontal collision, MOST pneumothoraces occur when:
Definition
the patient takes a deep breath just before impact and the lungs rapidly decompress at the time of impact
Term
During a lateral impact collision:
Definition
trauma to the upper extremities depends on the spatial orientation of the arms upon impact
Term
The severity of hypertension injuries to the neck following a rear-end collision depends MOSTLY on:
Definition
the position of the headrest
Term
Following a rotational impact, the MOST severely injured patients will likely be found at the point of:
Definition
greatest deceleration
Term
Which of the following statements regarding rollover motor vehicle crashes is correct?
Definition
Unrestrained passengers are struck with each change in the direction the car makes
Term
Which of the following is not a benefit of a properly worn seat belt?
Definition
minimal risk of whiplash injuries after a rear-end collision
Term
What type of injuries will MOST likely occur if a passenger is wearing his or her lap belt above the pelvic bone during a frontal impact?
Definition
Abdominal and lumbar spine
Term
All of the following statements regarding front air bags are correct, EXCEPT:
Definition
Air bags will provide protection from both initial and secondary impacts
Term
Common air bag- related injuries include:
Definition

Term
Lap belts that are worn alone and too high by a pregnant woman:
Definition
allow enough forward flexion and subsequent compression to rupture the uterus
Term
Structural protection afforded to a motorcycle rider during a crash comes from

Term
Following a head-on collision of a motorcycle and a truck, the motorcyclist would MOST likely experience initial injury to the
Definition

Term
After a motorcyclist is ejected from his or her motorcycle, secondary collisions:
Definition
cause an unpredictable combination of blunt injuries
Term
When an adult pedestrian is struck by a motor vehicle, lateral and posterior injuries are most common because
