TNCC 8th Edition questions and answers
2026\2027 A+ Grade
What are the greatest risks for transport?
- correct answer Loss of airway patency, displaced obstructive tubes lines or catheters, dislodge splinting
devices, need to replace or reinforce dressings, deterioration in patient status change in vital signs or
level of consciousness, injury to the patient and/or team members
According to newtons law which of these two force is greater: size or force?
- correct answer Neither. For each force there is an equal and opposite reaction.
What is the relationship between mass and velocity to kinetic energy?
- correct answer Kinetic energy is equal to 1/2 the mass multiplied the square of its velocity therefore
when mass is doubled so is the net energy, however, when velocity is doubled energy is quadrupled.
What is tension?
- correct answer stretching force by pulling at opposite ends
What is compression?
- correct answer Crushing by squeezing together
What is bending?
- correct answer Loading about an axis. Bending causes compression on the side the person is bending
toward intention to the opposite side
What is shearing?
- correct answer Damage by tearing or bending by exerting faucet different parts in opposite directions
at the same time.
What is torsion?
- correct answer Torsion forces twist ends in opposite directions.
, What is combined loading?
- correct answer Any combination of tension compression torsion bending and/or shear.
What are the four types of trauma related injuries?
- correct answer Blunt, penetrating, thermal, or blast.
What are contributing factors to injuries related to blunt traumas?
- correct answer The point of impact on the patient's body, the type of surface that is hit, the tissues
ability to resist (bone versus soft tissue, air-filled versus solid organs), and the trajectory of force.
What are the seven patterns of pathway injuries related to motor vehicle accidents?
- correct answer Up and over, down and under, lateral, rotational, rear, roll over, and ejection.
Differentiate between the three impacts of motor vehicle impact sequence.
- correct answer The first impact occurs when the vehicle collided with another object. The second
impact occurs after the initial impact when the occupant continues to move in the original direction of
travel until they collide with the interior of the vehicle or meet resistance. The third impact occurs when
internal structures collide within the body cavity.
What are the three factors that contribute to the damage caused by penetrating trauma's?
- correct answer The point of impact, the velocity and speed of impact, and the proximity to the object.
What causes the primary effects of blast traumas?
- correct answer The direct blast effects. Types of injuries include last long, tympanic membrane rupture
and middle ear damage, abdominal hemorrhage and perforation, global rupture, mild Trumatic brain
injury.
What causes the secondary effects of blast traumas?
- correct answer Projectiles propelled by the explosion. Injuries include penetrating or blunt injuries or I
penetration.
What causes the tertiary effects of blast traumas?
- correct answer Results from individuals being thrown by the blast wind. Injuries include hole or partial
