TNCC 8th Edition 2025 (50questions and ANSWERS)
What are the greatest risks for transport? - ANS>>Loss of airway patency, displaced obstructive tubes line
or catheters, dislodge splinting devices, need to replace or reinforce dressings, deterioration in patien
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? - ANS>>Neither. For eac
force there is an equal and opposite reaction.
What is the relationship between mass and velocity to kinetic energy? - ANS>>Kinetic energy is equal t
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? - ANS>>stretching force by pulling at opposite ends
What is compression? - ANS>>Crushing by squeezing together
What is bending? - ANS>>Loading about an axis. Bending causes compression on the side the person i
bending toward intention to the opposite side
What is shearing? - ANS>>Damage by tearing or bending by exerting faucet different parts in opposit
directions at the same time.
What is torsion? - ANS>>Torsion forces twist ends in opposite directions.
What is combined loading? - ANS>>Any combination of tension compression torsion bending and/o
shear.
What are the four types of trauma related injuries? - ANS>>Blunt, penetrating, thermal, or blast.
, What are contributing factors to injuries related to blunt traumas? - ANS>>The point of impact on th
patient's body, the type of surface that is hit, the tissues ability to resist (bone versus soft tissue, air-fille
versus solid organs), and the trajectory of force.
What are the seven patterns of pathway injuries related to motor vehicle accidents? - ANS>>Up and ove
down and under, lateral, rotational, rear, roll over, and ejection.
Differentiate between the three impacts of motor vehicle impact sequence. - ANS>>The first impact occur
when the vehicle collided with another object. The second impact occurs after the initial impact when th
occupant continues to move in the original direction of travel until they collide with the interior of th
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? - ANS>>The poin
of impact, the velocity and speed of impact, and the proximity to the object.
What causes the primary effects of blast traumas? - ANS>>The direct blast effects. Types of injuries includ
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? - ANS>>Projectiles propelled by the explosion
Injuries include penetrating or blunt injuries or I penetration.
What causes the tertiary effects of blast traumas? - ANS>>Results from individuals being thrown by th
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? - ANS>>All explosion related injuries, illnesses, o
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? - ANS>>Those associated with exposure to hazardou
materials from radioactive, biologic, or chemical components of a blast. Injuries include a variety of healt
effects depending on agent.
What are the three processes that transfer oxygen from the air to the lungs and blood stream
ANS>>Ventilation: the active mechanical movement of air into and out of the lungs; diffusion: the passiv
movement of gases from an area of higher concentration to an area of lower concentration; and perfusion
the movement of blood to and from the lungs as a delivery medium of oxygen to the entire body.
