EMT Chapter 27: Trauma Overview: The Trauma Patient and the Trauma System post test

the bullet strikes the body at a higher velocity

A bullet fired from a gun does more damage than a knife propelled by a human hand​ because:

Inertia

A patient who was restrained in his car was involved in a​ head-on collision. Despite his not contacting any internal structure in the​ car, he sustained a myocardial contusion. What law of motion describes this​ injury?

​10%

Approximately what percentage of trauma victims are multisystem trauma​ patients?

Compression injury

As blunt impact abruptly halts a portion of the body and inertia causes the remaining anatomy to continue its​ motion, one tissue or organ is pushed into another. What type of injury is​ this?

​High-velocity penetrating trauma

Cavitation is a term that is typically associated with which type of​ trauma?

​Up-and-over pathway

Head injuries and chest injuries such as flail​ chest, blunt cardiac​ injury, and aortic tears commonly result from which pathway in an automobile​ collision?

specialty centers

Hospitals that do not have a trauma center designation but that focus on specific areas of trauma​ expertise, such as burns or spinal cord​ injury, are:

four times as harmful as the rock thrown at 1 foot per second because velocity is squared

If you were hit by a rock thrown at a velocity of 1 foot per​ second, then hit by the same rock thrown at 2 feet per​ second, the rock that was thrown at 2 feet per second would​ be:

preservation of the rest of the skeletal system

In a​ foot-first fall, flexing of the knees can result​ in:

can increase the severity of a whiplash injury

In a​ rear-end collision, a headrest that is in the fully down​ position:

Establishing a patent airway

In dealing with the victim of multisystem​ trauma, which item should receive your initial​ attention?

Significant hemorrhage

In treating the victim of multisystem​ trauma, what should be addressed after gaining control of the airway and​ ventilation?

Blunt trauma

In what form of trauma does the energy exchange cause a chain reaction within various body tissues that​ crush, stretch, and tear their​ structures, resulting in injury at and beneath the​ skin's surface?

Distance and point of impact

On what factor does the pattern of tertiary phase injuries​ depend?

pulmonary injuries

The MOST common and serious primary phase injuries produced from a blast​ are:

velocity

The amount of kinetic energy that a moving body contains is based on its mass​ and:

kinetics

The branch of mechanics that deals with the movements of bodies is called:

the arms

The first point of impact in​ head-first falls is​ typically:

a person was injured

The mechanism of injury refers to​ how:

to maintain a high index of suspicion if any passenger appears confused

Vehicle collisions are a common mechanism of injury. It is important to​ remember:

Laying the bike down

What is the term for an evasive action on the part of a motorcycle rider that is designed to prevent ejection and separation of the driver from the bike in an impending​ collision?

​Head-on

What type of motorcycle impact results in the rider traveling into the​ handlebars?

fragmentation

When a projectile breaks into smaller​ pieces, increasing the amount of damage to the​ body, this process is called

another occupant killed

When caring for the victim of a motor vehicle​ collision, the EMT should suspect critical injuries if there​ was:

level of consciousness

When triaging a​ patient, of the​ following, you should first assess​ the:

A general hospital with some surgical capability and a commitment to special staff training and resource allocation for trauma patients

Which definition would accurately describe a Level III trauma​ center?

Systolic blood pressure less than 90

Which of the following vital signs indicates the need for transport to a trauma​ center?

​Yes, because of the altered mental status and closed head injury

You are treating a​ 36-year-old female patient who was involved in a motor vehicle crash. She was not wearing a seat belt. A bystander states that the patient was initially unconscious at the scene before your arrival. There is no apparent external trauma aside from a bruise on the front of her head. Is this a patient who is a high priority for rapid​ transport?
