,8. Manage and optimize performance outcomes
9. Interdependent and adaptive
What are the key foundations to successful teamwork in the care of the trauma
patient? - Correct answer-1. Communication
2. Cooperation
3. Coordination
What tools can be used to promote communication within a team member? What
are the benefits of each? - Correct answer-1. *SBAR:* Situation, Background,
Assessment, Recommendations-To provide a framework for communication
among members of the healthcare team
2. *DESC:* Describe the specific situation or behavior, Express your concerns or
how the situation makes you feel, Suggest alternatives and seek agreement, state
Consequences in terms of impact on performance goals-Used in conflict
management, paraphrasing the other person's comments is an important technique
that should be done throughout the DESC support

,3. *CUS:* I am Concerned, I am Uncomfortable, This is a Safety issue/I am
Stressed-Used to "stop the line" if a team member senses or discovers an essential
safety breach
Kinematics - Correct answer-The study of energy transfer as it applies to
identifying actual or potential injuries
Biomechanics - Correct answer-The general study of forces and their effects
Mechanism of Injury - Correct answer-How external energy forces in the
environment are transferred to the body
Newton's First Law of Motion - Correct answer-A body rest will remain at rest, and
a body in motion will stay in motion
Newton's Second Law of Motion - Correct answer-Force = mass x acceleration
Newton's Third Law of Motion - Correct answer-For every action, there is an equal
and opposite reaction
Law of Conservation of Energy - Correct answer-Energy can neither be created nor
destroyed, but can change form
Describe how Newton's Laws of Motion and the Law of Conservation affect
energy transfer in traumatic injury, and give an example - Correct answer--1st:

, weight and speed are reasonable substitutions for mass and velocity, higher mass
and/or higher speed delivers greater energy
-2nd: an object's velocity changes when it is subjected to an external force; heavier
objects require more force to accelerate (or decelerate) them
-3rd:
-Conservation:
Ex: pot vs. child
-1st: the force of gravity holds the pot on the flat stovetop until energy is
transferred to the pot, such as by a toddler, grabbing the handle.Once the pot is in
motion, it will sustain its motion until interrupted by another force. As the pot
strikes the child in the head, the strength of bone imposes a force of resistance
upon impact, thereby changing the directional path of the pot. The stationary head
stays in a fixed position until a volume of energy adequate to move the head is
transferred to it. This concept of movement-energy transfer-countermovement
applies to all mechanical traumas
-2nd: the pot continues to fall at a steady rate unless it is acted on by an outside
force (a hand pushing it out of the way or catching it)
