TNCC 10TH EDITION
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 forces 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.
