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