What roles are vital to a trauma team? - ANSWER: -The patient
-The team leader
-Core team
-Contigency and support services
What are the characteristics of an effective team? - ANSWER: - Clear roles and
responsibilities
- Shared mental model
- Optimize resources
- Strong team leadership
- Engage in regular discipline of feedback
- Strong sense of collective trust and confidence
- Create mechanisms to cooperate and coordinate
- Manage and optimize performance outcomes
-Interdependent and adaptive
What tools can be used to promote communication within a team structure? What
are the benefits of each? - ANSWER: - Brief: designed to form the team, designate
team roles and responsibilities, establish climate and goals, and engage the team in
short and long-term planning
- Huddle: ideally convened prior to trauma patient's arrival; communicate critical
issues and emerging events, anticipate outcomes and likely contingencies, assign
resources, express concerns
- Debrief: process improvement
Define trauma - ANSWER: Injury to living tissue caused by an extrinsic agent; creates
stressors that exceed tissue or organ's ability to compensate
Define epidemiology - ANSWER: Study of factors that determine and influence the
frequency and distribution of injury, disease, and other health-related events and
their causes in a defined human population
When is the potential for traumatic injury present? - ANSWER: Whenever energy
comes in contact with the human body
Define kinematics - ANSWER: The study of energy transfer as it applies to identifying
actual or intentional injuries
,Define biomechanics - ANSWER: The general study of forces and their effects
Define mechanism of injury - ANSWER: How external forces are transferred to the
body, resulting in injury
Define potential energy - ANSWER: Stored energy; "at rest"
Define kinetic energy - ANSWER: Energy in motion
Describe Newton's First Law of Motion - ANSWER: A body at rest will remain at rest,
and a body in motion will stay in motion unless acted upon by an outside force
(energy)
Describe Newton's Second Law of Motion - ANSWER: (F)orce = (m)ass x
(a)cceleration; It takes more force to move a heavy object
Describe Newton's Third Law of Motion - ANSWER: For every action, there is an
equal and opposite reaction resulting from the transfer of energy
Describe the Law of Conservation of Energy - ANSWER: Energy can neither be
created nor destroyed, but it can change form
What are the five forms in which energy exist? - ANSWER: - Mechanical: direct
impact of an object
- Thermal
- Chemical
- Electrical
- Radiant
The consequences of mechanical energy are directly related to __________ energy -
ANSWER: Kinetic
Kinetic Energy (KE) is equal to - ANSWER: 1/2 the mass multiplied by the velocity
squared
In other words: when mass is doubled, energy is doubled; when velocity is doubled,
energy is quadrupled
Kinetic Energy formula - ANSWER: KE=1/2mv^2
Differentiate between internal and external forces of energy transfer in the context
or trauma. - ANSWER: External forces are how energy can impact the body (e.g.,
deceleration, acceleration, compression). Internal forces represent the ability of the
body to withstand external forces.
How do internal forces protect the body from injury? - ANSWER: - Compression
strength: ability of tissue to resist crush injury or force
, - Tensile strength: ability to resist being pulled apart when stretched
- Shear strength: ability to resist a force applied parallel to the tissue
List four main types of traumatic injury - ANSWER: - Blunt trauma
- Penetrating trauma
- Thermal trauma
- Blast trauma
Examples of blunt trauma - ANSWER: Falls
MVA
Vehicle vs. pedestrian collisions
Assaults
*Can result from broad energy impacts across large surface areas and involve energy
transfer causing deceleration or acceleration
*Greater distance of transfer diminishes deleterious impacts, and the more focused
the impact, the greater the damage
Deceleration injuries - ANSWER: Occurs as energy is dispersed from the moving
object
* The speed of an impact is often less significant than the distance over which the
energy is transferred
Differentiate between deceleration and acceleration forces. - ANSWER: pg. 28
What environmental and pathophysiologic factors are considered when the
mechanism of injury is a fall? - ANSWER: - Point of impact
- Type of surface that is hit
- Tissue's ability to resist
- Acceleration
When is a fall considered significant in the pediatric patient? - ANSWER: If the fall is
from three times his or her height
Describe the three impacts in the motor vehicle impact sequence. - ANSWER: 1.
Vehicle hits another object
2. Occupant hits interior of vehicle (energy of impacts limited by seatbelt and airbag)
3. Organs hit other internal structures
*Organs continue in motion and can be torn away from their attachments
Examples of penetrating trauma - ANSWER: - Gunshot
