Contingency and support services What are the characteristics of an effective team? Correct Answer 1. Clear roles and responsibilities 2. Shared mental model 3. Optimize resources 4. Strong team leadership 5. Engage in regular discipline of feedback 6. Strong sense of collective trust and confidence 7. Create mechanisms to cooperate and coordinate 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) -3rd: the transfer causes a redirection of the pot and movement of the head, as well as energy absorption causing anatomic changes to the tissue that received the energy transfer -Conservation: energy is not created, nor it is destroyed at the site where the pot impacts the head. Instead, energy is transferred from the kinetic (moving) object to the object being impacted What are the five forms in which energy exist? Correct Answer 1. *Mechanical:* energy transfer form one object to another in the form of motion 2. *Thermal:* energy transfer of heat in the environment to the host 3. *Chemical:* heat energy transfer from active chemical substances, chlorine, drain cleaner, acids, or plants 4. *El
