TNCC STURDY GUIDE |VERIFIED QUESTIONS AND CORRECT DETAILED
ANSWERS|RATED AND GRADED A+ NEW UPDATE| 2026/2027
What roles are vital to a trauma team - ANSWER✔ The patient
Team leader-organize team/empower members
core team-technical skills- airway/vascular access
contingency and support survices- RT
Characterisitcs of an effective team - ANSWER✔ dynamic
interdependent
adaptive
common goal
COMMUNICATION
COOPERATION
COORDINATION
Kinematics - ANSWER✔ study of energy transfer as it applies to identifying actual or potential injuries
Biomechanics - ANSWER✔ general study of forces and their effects
mechanism of injury - ANSWER✔ how external energy forces in the environment are transferred to
the body
Newtons 3 laws - ANSWER✔ 1. an object in motion will stay in motion
2. force = mass x acceleration
3. for every action there is an equal and opposite reaction
,5 forms of energy that exist - ANSWER✔ 1. Mechanical- energy transfer from one object to another
in form of motion
2. thermal-heat transfer from environment to host
3. chemical- heat energy trnsfer from active chemical substances such as chlorine, drain cleaner, acids
4. electrical- energy transfer from light socket
5. radiant- energy transfer from blast sound waves, nuclear, rays from the sn
eternal forces in trauma - ANSWER✔ 1. deceleartion- falls and collison = sudden stop
2. acceleration- sudden onset of motion- hit by a car
3. compression- hit stationary objects; bullets; blast forces
internal forces of energy in trauma - ANSWER✔ stress- internal force that resists external force
solid organs good at pressure wave energy
air organs better at shear forces
4 main types of traumatic injury - ANSWER✔ 1. blunt trauma- falls; mvc; trauma
2. penetrating- stabing; GSW
3. Thermal
4. Blast Trauma- bomb
deceleration vs acceleration forces - ANSWER✔ -Deceleration: injury that occurs as pt slows down
,acceleration injury: injury that occurs as a result of other parts of the body stopping before the organs
do (concussion; shearing of aorta)
environment and pathophysiology when MOI is a fal - ANSWER✔ -point of impact on the body
-type of surface that is hit
-tissues ability to resist injury (bone is less flexible)
-pt pushed = more acceleration
3 impacts in a MVC - ANSWER✔ 1. vehicle hits another object: occupant = acceleration
2. occupant collides with interior of vehicle: internal organs continue
3. internal structure collide with body
5 mechanisms of injury in a blast trauma - ANSWER✔ Primary: blast injury; air-filled organs at risk to
rupture
secondary: fragment injuries; puncture wounds; lacerations
tertiary: impacts with larger objectes propelled by the blast win causing blunt trauma
quaternary: heat/flame/gas and smoke
quinary: exposure to hazardous materials (radioactive)
Haddon Matrix in prevention and reduction of injury - ANSWER✔ places emphasis on
countermeasures at preventing injury more than changing human behvior such as airbags, vehicle
design and road blueprints
, why is there repeated emphasis on assessment for hemorrhage through the initial emphasis -
ANSWER✔ uncontrolled hemorrhage is teh majore causae of preventable death after injury
Which tool can be used to rapidly assess the level of consciousness during the A - Airway and Alertness
step?
Why is it important to determine alertness along with airway? What are the components of this tool? -
ANSWER✔ A- alert
*any below here may have compromised airway
V- verbal stimuli
P-painful stimuli
U- unresponsive
Which method of opening the airway is recommended for use in trauma? - ANSWER✔ Jaw thrust
maneuver w/ one provider stabilizing c-spine
Assessment of airway - ANSWER✔ Insect for tongue obstruction; loose/missing teeth;
foreign objects;
blood, vomit, secretion;
edema
inhalation injury;
listen for gurgling/snoring/stridor;
palpate for occlusive maxillofacial bony deformity; subcutaneous emphysema
Describe the current guidelines for volume resuscitation in hemorrhagic shock. - ANSWER✔ 2 large
bore IVs
1-2L fluid warmed flui
replace what is lost
