Trauma Overview

Question 1

Air bubbles in the arterial blood vessels

Answer 1

Arterial air embolism

Question 2

An impact on the body by objects that cause injury without penetrating soft tissues or internal organs and cavities

Answer 2

Blunt trauma

Question 3

A phenomenon in which speed causes a bullet to generate pressure waves, which cause damage distant from the bullet’s path

Answer 3

Cavitation

Question 4

A brain injury that occurs when force is applied to the head and energy transmission through brain tissue causes injury on the opposite side of original impact; coup injury occurs at the point of impact; contrecoup injury occurs on the opposite side of impact, as the brain rebounds

Answer 4

Coup-contrecoup brain injury

Question 5

The slowing of an object

Answer 5

Deceleration

Question 6

Resistance that slows a projectile, such as air

Answer 6

Drag

Question 7

An evaluation tool used to determine level of consciousness, which evaluates and assigns point values (scores) for eye opening, verbal response, and motor response, which are then totaled; effective in helping predict patient outcomes

Answer 7

Glasgow Coma Scale

Question 8

Awareness that unseen life- threatening injuries may exist when determining the mechanism of injury

Answer 8

Index of suspicion

Question 9

The energy of a moving object

Answer 9

Kinetic energy

Question 10

Emergencies that require EMS attention because of illnesses or conditions not caused by an outside force

Answer 10

Medical emergencies

Question 11

Trauma that affects more than one body system

Answer 11

Multi system trauma

Question 12

Injury caused by objects, such as knives and bullets, that pierce the surface of the body and damage internal tissues and organs

Answer 12

Penetrating trauma

Question 13

The product of mass, gravity, and height, which is converted into kinetic energy and results in injury, such as from a fall

Answer 13

Potential energy

Question 14

Any object propelled by force, such as a bullet by a weapon

Answer 14

Projectile

Question 15

Pulmonary trauma resulting from short-range exposure to the detonation of high-energy explosives

Answer 15

Pulmonary blast injuries

Question 16

A scoring system used for patients with head trauma

Answer 16

Revised Trauma Score

Question 17

The path a projectile takes once it is propelled

Answer 17

Trajectory

Question 18

Emergencies that are the result of physical forces applied to a patient’s body

Answer 18

Trauma emergencies

Question 19

A score calculated from 1 to 16, with 16 being the best possible score. It relates to the likelihood of patient survival with the exception of a severe head injury. It takes into account the Glasgow Coma Scale (GCS) score, respiratory rate, respiratory expansion, systolic blood pressure, and capillary refill

Answer 19

Trauma score

Question 20

The eardrum; a thin, semitransparent membrane in the middle ear that transmits sound vibrations to the internal ear by means of auditory ossicles

Answer 20

Tympanic membrane

Question 21

The measure of force over distance

Answer 21
