fully solved & updated 2025-2026(latest version verified for accuracy)
(Questions + Answers) Solved 100% Correct!!
Components of SBAR and its purpose - correct answer S: Situation
B: Background
A: Assessment
R: Recommendation
Purpose- to provide framework for communication amount members of the healthcare team
p. 7
Components of DESC and its purpose - correct answer D: Describe the specific situation or
behavior
E: Express your concerns or how the situation makes you feel
S: Suggest alternatives and seek agreement
C: State consequences in terms of impact on performance goals
Purpose- used in conflict management; paraphrasing the other person's comments is an
important technique that should be done throughout the DESC script. Following discussion of
consequences, team members should work towards consensus.
p. 7
Components of CUS and its purpose - correct answer C: I am Concerned
U: I am Uncomfortable
S: This is a Safety issue/ I am Stressed
Purpose- used to "stop the line" if a team member senses or discovers an essential safety
breach
p. 7
Define trauma - correct answer - Trauma is injury to living tissue caused by extrinsic agent
,- Regardless of MOI, trauma creates stressors that exceed the tissue's or organ's ability to
compensate
p. 9
Leading cause of death for ages
1. over 65
2. 5 to 24
3. 25 to 64 - correct answer 1. Falls
2. MVCs
3. poisoning
p. 9
Explain 3 phases of injury prevention - correct answer Primary: prevention of the occurrence of
the injury
Secondary: Reduction in the severity of the injury that has occurred
Tertiary: Improvement of outcomes related to the traumatic injury
p. 10
Describe the three E's of injury control - correct answer Engineering: technological
interventions such as side impact airbags, automated blind spot alarms, ignition lock devices for
those with DUIs. In playgrounds and sports, this involves surface material under playground
equipment and athletic safety gear. Another intervention is improved use of smoke alarms in
fire prevention
Enforcement and legislation: include laws at all jurisdictional levels regarding driving while
intoxicated, booster seats, primary seatbelt use, and distracted driving. For sports this includes
rules regarding illegal hits, examination after impact, and return-to-play requirements after a
head injury
,Education: these can be community-based initiatives such as public service announcements for
improved seatbelt use, education regarding risks of distracted driving, programs to commit to
no texting while driving, and promotions for bicycle helmet giveaways with instructions for
proper use
p. 11
How can the trauma nurse have an impact when it comes to the legislative process? - correct
answer By advocating for stronger laws and more consistent enforcement
p. 11
Define kinematics - correct answer The study of energy transfer as it applies to identifying
actual or intentional injuries
p. 25
Define biomechanics - correct answer The general study of forces and their effects
p. 25
Define mechanism of injury (MOI) - correct answer How external energy forces in the
environment are transferred to the body
p. 25
Newton's First Law of Motion - correct answer A body at rest will remain at rest, and a body in
motion will stay in motion
p. 26
Newton's Second Law of Motion - correct answer Force = Mass X Acceleration
p. 26
Newton's Third Law of Motion - correct answer For every action, there is an equal and opposite
reaction
, p. 26
Law of Conservation of Energy - correct answer Energy can neither be created nor destroyed,
but it can change form
p. 26
Describe energy forms - correct answer - Mechanical (energy transfer from one object to
another in the form of motion)
- Thermal (energy transfer of heat in environment to the host)
- Chemical (heat energy transfer from active chemical substances such as chlorine, drain
cleaner, acids, or plants)
- Electrical (energy transfer from light socket, power lines, or lightning)
- Radiant (energy transfer from blast sound waves, radioactivity such as a nuclear facility, or
rays of the sun)
p. 26
External energy forces can be exerted on the body by the following forces - correct answer -
Deceleration forces: include those applied in falls and collisions where injuries are caused by
sudden stop of the body's motion
- Acceleration forces: not as common as deceleration forces and result from a sudden and rapid
onset of motion (parked car being hit by a vehicle traveling at a high rate of speed)
- Compression force is an external force applied at times of impact, explains include:
+ Stationary objects such as dashboards or steering wheels, that collide with or push up into a
person
+ Objects in motion such as bullets and stabbing instruments, bats and balls, fists and feet, or
heavy falling objects
+ Blast forces
