WRITTEN EXAM QUESTIONS AND ACCURATE ANSWERS.
What roles are vital to a trauma team? - ANSWER >> The patient
-The team leader
-Core team
-Contingency 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 are key foundations to successful teamwork in the care of the trauma patient? - - ANSWER
>> care coordination, clear communication, and timely systematic assessment
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
