TNCC 8th Edition (A GRADED AND REVIEWED 2023)
Questions And Answers.
What are the greatest risks for transport? - Correct Answers 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? - Correct
Answers Neither. For each force there is an equal and opposite reaction.
What is the relationship between mass and velocity to kinetic energy? - Correct
Answers 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? - Correct Answers stretching force by pulling at opposite ends
What is compression? - Correct Answers Crushing by squeezing together
What is bending? - Correct Answers Loading about an axis. Bending causes
compression on the side the person is bending toward intention to the opposite side
What is shearing? - Correct Answers Damage by tearing or bending by exerting faucet
different parts in opposite directions at the same time.
What is torsion? - Correct Answers Torsion forces twist ends in opposite directions.
What is combined loading? - Correct Answers Any combination of tension compression
torsion bending and/or shear.
What are the four types of trauma related injuries? - Correct Answers Blunt,
penetrating, thermal, or blast.
What are contributing factors to injuries related to blunt traumas? - Correct Answers
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? -
Correct Answers Up and over, down and under, lateral, rotational, rear, roll over, and
ejection.
Differentiate between the three impacts of motor vehicle impact sequence. - Correct
Answers 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? - Correct Answers The point of impact, the velocity and speed of impact, and
the proximity to the object.
What causes the primary effects of blast traumas? - Correct Answers 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? - Correct Answers Projectiles
propelled by the explosion. Injuries include penetrating or blunt injuries or I penetration.
What causes the tertiary effects of blast traumas? - Correct Answers 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? - Correct Answers 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? - Correct Answers 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.
What are the three processes that transfer oxygen from the air to the lungs and blood
stream - Correct Answers Ventilation: the active mechanical movement of air into and
out of the lungs; diffusion: the passive 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.
When would you use a nasopharyngeal airway versus an oral pharyngeal airway? -
Correct Answers Nasopharyngeal airways is contraindicated in patients with facial
trauma or a suspected basilar skull fracture. Oral pharyngeal airways is used in
unresponsive patients unable to maintain their airway, without a gag reflex as a
temporary measure to facilitate ventilation with a bag mask device or spontaneous
ventilation until the patient can be intubated.
