TNCC 8th Edition Questions and
Answers (2023 Updated Bank)
What are the greatest risks for transport? - (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? - (Answer)Neither. For each
force there is an equal and opposite reaction.
What is the relationship between mass and velocity to kinetic energy? - (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? - (Answer)stretching force by pulling at opposite ends
What is compression? - (Answer)Crushing by squeezing together
What is bending? - (Answer)Loading about an axis. Bending causes compression on the side the person
is bending toward and tension to the opposite side
What is shearing? - (Answer)Damage by tearing or bending by exerting force different parts in opposite
directions at the same time.
What is torsion? - (Answer)Torsion forces twist ends in opposite directions.
What is combined loading? - (Answer)Any combination of tension compression torsion bending and/or
shear.
What are the four types of trauma related injuries? - (Answer)Blunt, penetrating, thermal, or blast.
What are contributing factors to injuries related to blunt traumas? - (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? - (Answer)Up and
over, down and under, lateral, rotational, rear, roll over, and ejection.
