What are the greatest risks for transport? - Loss of airway patency, displaced obstructive
II II II II II II II II II II II II II II II
tubes lines or catheters, dislodge splinting devices, need to replace or reinforce
II II II II II II II II II II II II
dressings, deterioration in patient status change in vital signs or level of consciousness,
II II II II II II II II II II II II II
injury to the patient and/or team members
II II II II II II II
According to newtons law which of these two force is greater: size or force? - Neither.
II II II II II II II II II II II II II II II II II II II
For each force there is an equal and opposite reaction.
II II II II II II II II II II
What is the relationship between mass and velocity to kinetic energy? - Kinetic energy is
II II II II II II II II II II II II II II II II II II
equal to 1/2 the mass multiplied the square of its velocity therefore when mass is doubled
II II II II II II II II II II II II II II II II
so is the net energy, however, when velocity is doubled energy is quadrupled.
II II II II II II II II II II II II II
II IIWhat is tension? - stretching force by pulling at opposite ends
II II II II II II II II II II II II
II IIWhat is compression? - Crushing by squeezing together
II II II II II II II II II
What is bending? - Loading about an axis. Bending causes compression on the side the
II II II II II II II II II II II II II II II II II II
person is bending toward intention to the opposite side
II II II II II II II II II
What is shearing? - Damage by tearing or bending by exerting faucet different parts in
II II II II II II II II II II II II II II II II II II
opposite directions at the same time.
II II II II II II
II IIWhat is torsion? - Torsion forces twist ends in opposite directions.
II II II II II II II II II II II II
What is combined loading? - Any combination of tension compression torsion bending
II II II II II II II II II II II II II II II
and/or shear.
II II
II IIWhat are the four types of trauma related injuries? - Blunt, penetrating, thermal, or blast.
II II II II II II II II II II II II II II II II
What are contributing factors to injuries related to blunt traumas? - The point of impact
II II II II II II II II II II II II II II II II II II
on the patient's body, the type of surface that is hit, the tissues ability to resist (bone
II II II II II II II II II II II II II II II II II
versus soft tissue, air-filled versus solid organs), and the trajectory of force.
II II II II II II II II II II II II
What are the seven patterns of pathway injuries related to motor vehicle accidents? - Up
II II II II II II II II II II II II II II II II II II
and over, down and under, lateral, rotational, rear, roll over, and ejection.
II II II II II II II II II II II II
Differentiate between the three impacts of motor vehicle impact sequence. - The first
II II II II II II II II II II II II II II II II
impact occurs when the vehicle collided with another object. The second impact occurs
II II II II II II II II II II II II II
after the initial impact when the occupant continues to move in the original direction of
II II II II II II II II II II II II II II II
, travel until they collide with the interior of the vehicle or meet resistance. The third impact
II II II II II II II II II II II II II II II II
occurs when internal structures collide within the body cavity.
II II II II II II II II II
What are the three factors that contribute to the damage caused by penetrating
II II II II II II II II II II II II II II
trauma's? - The point of impact, the velocity and speed of impact, and the proximity to the
II II II II II II II II II II II II II II II II II II II
object.
II
What causes the primary effects of blast traumas? - The direct blast effects. Types of
II II II II II II II II II II II II II II II II II II
injuries include last long, tympanic membrane rupture and middle ear damage,
II II II II II II II II II II II
abdominal hemorrhage and perforation, global rupture, mild Trumatic brain injury.
II II II II II II II II II II
What causes the secondary effects of blast traumas? - Projectiles propelled by the
II II II II II II II II II II II II II II II II
explosion. Injuries include penetrating or blunt injuries or I penetration.
II II II II II II II II II II
What causes the tertiary effects of blast traumas? - Results from individuals being
II II II II II II II II II II II II II II II II
thrown by the blast wind. Injuries include hole or partial body translocation from being
II II II II II II II II II II II II II II
thrown against a hard service: blunt or penetrating trauma's, fractures, traumatic
II II II II II II II II II II II
amputations.
II
What causes quarternary effects of blast traumas? - All explosion related injuries,
II II II II II II II II II II II II II II II
illnesses, or diseases not due to the first three mechanisms. Injuries include external and
II II II II II II II II II II II II II II
internal burns, crush injuries, closed and open brain injuries, asthmatic or breathing
II II II II II II II II II II II II
problems from dust smoke or toxic fumes, angina, or hyper glycemia and hypertension.
II II II II II II II II II II II II II
What causes quinary effects of blasts traumas? - Those associated with exposure to
II II II II II II II II II II II II II II II II
hazardous materials from radioactive, biologic, or chemical components of a blast.
II II II II II II II II II II II
Injuries include a variety of health effects depending on agent.
II II II II II II II II II II
What are the three processes that transfer oxygen from the air to the lungs and blood
II II II II II II II II II II II II II II II II II
stream - Ventilation: the active mechanical movement of air into and out of the lungs;
II II II II II II II II II II II II II II II II II
diffusion: the passive movement of gases from an area of higher concentration to an area
II II II II II II II II II II II II II II II
of lower concentration; and perfusion: the movement of blood to and from the lungs as a
II II II II II II II II II II II II II II II II
delivery medium of oxygen to the entire body.
II II II II II II II II
When would you use a nasopharyngeal airway versus an oral pharyngeal airway? -
II II II II II II II II II II II II II II II II
Nasopharyngeal airways is contraindicated in patients with facial trauma or a suspected
II II II II II II II II II II II II
basilar skull fracture. Oral pharyngeal airways is used in unresponsive patients unable to
II II II II II II II II II II II II II
maintain their airway, without a gag reflex as a temporary measure to facilitate ventilation
II II II II II II II II II II II II II II
with a bag mask device or spontaneous ventilation until the patient can be intubated.
II II II II II II II II II II II II II II
Describe the measurement of an NPA - Measure from the tip of the patient's nose to the
II II II II II II II II II II II II II II II II II II II II
tip of the patients earlobe.
II II II II II
Measurement of an OPA - Place the proximal end or flange of the airway adjunct at the
II II II II II II II II II II II II II II II II II II II II
corner of the mouth to the tip of the mandibular angle.
