TNCC 8th Edition (A GRADED AND REVIEWED
2023/ 2024 detailed Questions And
Answers)/latest update 2025
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 intention to the opposite side
What is shearing? - .....ANSWER ...✔✔ Damage by
tearing or bending by exerting faucet 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.
Differentiate between the three impacts of motor vehicle
impact sequence. - .....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? - .....ANSWER
...✔✔ The point of impact, the velocity and speed of
impact, and the proximity to the object.
