TNCC 8TH EDITION QUESTIONS WITH ANSWERS 2022
What are the greatest risks for transport? - 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? - Neither. For each force
there is an equal and opposite reaction.
What is the relationship between mass and velocity to kinetic energy? - 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? - stretching force by pulling at opposite ends
What is compression? - Crushing by squeezing together
What is bending? - Loading about an axis. Bending causes compression on the side the person is bending
toward intention to the opposite side
What is shearing? - Damage by tearing or bending by exerting faucet different parts in opposite
directions at the same time.
What is torsion? - Torsion forces twist ends in opposite directions.
What is combined loading? - Any combination of tension compression torsion bending and/or shear.
What are the four types of trauma related injuries? - Blunt, penetrating, thermal, or blast.
, What are contributing factors to injuries related to blunt traumas? - 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? - Up and over,
down and under, lateral, rotational, rear, roll over, and ejection.
Differentiate between the three impacts of motor vehicle impact sequence. - 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? - The point
of impact, the velocity and speed of impact, and the proximity to the object.
What causes the primary effects of blast traumas? - 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? - Projectiles propelled by the explosion. Injuries
include penetrating or blunt injuries or I penetration.
What causes the tertiary effects of blast traumas? - 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? - 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.
