TNCC Trauma Nursing Core Course 7th Edition ENA Questions
and correct Answers
In-class activity
Components of SBAR and its purpose Correct Answers 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 Answers 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 Answers 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 Answers - 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 Answers 1. Falls
2. MVCs
3. poisoning
p. 9
Explain 3 phases of injury prevention Correct Answers 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 Answers 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 Answers By
advocating for stronger laws and more consistent enforcement
p. 11
Define kinematics Correct Answers The study of energy transfer as it applies to identifying actual or
intentional injuries
p. 25
Define biomechanics Correct Answers The general study of forces and their effects
p. 25
Define mechanism of injury (MOI) Correct Answers How external energy forces in the environment are
transferred to the body
p. 25
Newton's First Law of Motion Correct Answers 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 Answers Force = Mass X Acceleration
, p. 26
Newton's Third Law of Motion Correct Answers For every action, there is an equal and opposite reaction
p. 26
Law of Conservation of Energy Correct Answers Energy can neither be created nor destroyed, but it can
change form
p. 26
Describe energy forms Correct Answers - 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 Answers -
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
