TNCC 8TH EDITION 2023 QUESTIONS AND
ANSWERS FULLY CORRECT (52 SETS) GRADED A+
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.
What causes the primary effects of blast traumas? - 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? - ANSWER Projectiles propelled by the
explosion. Injuries include penetrating or blunt injuries or I penetration.
What causes the tertiary effects of blast traumas? - ANSWER Results from individuals being
thrown by the blast wind. Injuries include hole or partial body translocation from being thrown against
a hard service: blunt or penetrating trauma's, fractures, traumatic amputations.
What causes quarternary effects of blast traumas? - ANSWER All explosion related injuries,
illnesses, or diseases not due to the first three mechanisms. Injuries include external and internal
burns, crush injuries, closed and open brain injuries, asthmatic or breathing problems from dust
smoke or toxic fumes, angina, or hyper glycemia and hypertension.
What causes quinary effects of blasts traumas? - ANSWER Those associated with exposure to
hazardous materials from radioactive, biologic, or chemical components of a blast. Injuries include a
variety of health effects depending on agent.
