CONCEPTS!!!
1.Kinetic energy is a calculation of:

C.mass and weight.
D.speed and force. - <<ANSWER>>B.weight and speed.
Rationale: Kinetic energy is a calculation of mass (weight) and velocity (speed). Energy

You and your partner are dispatched to the rodeo arena for a person reporting
shortness of breath and chest pain. On arrival you are escorted to a first aid trailer
where you find a man in his mid 30s seated in a chair and leaning forward clutching his
chest. He tells you that he was riding a bull when he was thrown off. He states that he
landed hard on his right side and heard a "loud pop."

condition. What diagnostic tool is most commonly used to evaluate the effectiveness of
the respiratory system? A. Noninvasive transcutaneous thermometer B. Peak flow
meter C. Pulse oximeter D. Automated blood pressure cuff - <<ANSWER>>C. Pulse
oximeter

shortness of breath and chest pain. On arrival you are escorted to a first aid trailer
where you find a man in his mid 30s seated in a chair and leaning forward clutching his
,chest. He tells you that he was riding a bull when he was thrown off. He states that he
landed hard on his right side and heard a "loud pop."
7. While en route to the hospital, the patient suddenly grabs your arm and states that he
can't breathe. He appears pale, diaphoretic, and extremely anxious. Reassessment of
the chest reveals diminished breath sounds on the right side and subcutaneous
emphysema. You suspect which of the following conditions is developing in the patient?
A. Cardiac tamponade B. Tension pneumothorax C. Myocardial contusion D. Pulmonary
contusion - <<ANSWER>>B. Tension pneumothorax

where you find a man in his mid 30s seated in a chair and leaning forward clutching his
chest. He tells you that he was riding a bull when he was thrown off. He states that he
landed hard on his right side and heard a "loud pop."
8. You are still 30 minutes away from the hospital. On the basis of the patient's current
signs and symptoms, what is the most appropriate management? A. Assist ventilations
with a bag-mask device and continue transport. B. Call for ALS assistance and continue
transport. C. Reassure the patient and continue transport. D. Attempt to place a needle
in the right side of the chest. - <<ANSWER>>B. Call for ALS assistance and continue
transport.

9. How can a tension pneumothorax develop as the result of fractured ribs? -
<<ANSWER>>A great deal of anatomy lies underneath the ribs. A rib fragment can
puncture any of these structures, causing further problems. In the case of a tension
pneumothorax, a piece of the fractured rib punctures underlying lung tissue, causing air
to escape into the pleural cavity and placing pressure on the lung, causing it to collapse.
If a significant portion (30% to 40%) of the lung collapses, it begins to compress the
great vessels, impeding blood return to the heart, which causes JVD, as well as
pressing against the trachea, which causes tracheal deviation.

Spinal cord injury should be suspected in patients with chest injury. The intercostal
muscles receive nerve impulses from specific spinal nerves. Where are these nerves
,located? - <<ANSWER>>The spinal nerves originating in the cervical regions C6 and
C7 provide nervous stimulation to the intercostal muscles, providing the ability for the
thoracic cage to elevate during inspiration
2.A 20-year-old man has major open facial injuries after his vehicle struck a tree head-
on. Which of the following findings within the car would MOST likely explain his injury
pattern?
A.Deployed airbag
B.Bent steering wheel
C.Nonintact windshield
D.Crushed instrument panel - <<ANSWER>>C.Nonintact windshield
Rationale: The mechanism of injury and condition of the vehicle's interior suggest likely
areas of injury. Head and neck injuries are likely to result when the head and face
impact the windshield.
deployed airbags typically result in abrasions of the face, head, and arms // bent
steering wheel tyoically indicates the presence of chest injuries // crushed instrument
panel typically indictaes the presence of leg and hip injuries
3.Which of the following would MOST likely result from the third collision in the "three-
collision" effect that occurs during a high-speed, frontal impact motor vehicle crash?
A.Extensive damage to the automobile
B.Flail chest and lower extremity fractures
C.Massive external trauma with severe bleeding
D.Aortic rupture or compression injury to the brain - <<ANSWER>>D.Aortic rupture or
compression injury to the brain
Rationale: During the third collision, the body's internal organs collide with the inside of
the body. These injuries are usually not as obvious, but are often the most life-
threatening. Injuries that may result from this include internal injuries of the brain
(compression injuries) and aortic tears, resulting in massive internal bleeding.
A would occur in first collision (vehicle vs other object); B & C would occur in second
collision (person vs vehicle)
4.A young male experienced severe blunt chest trauma when his passenger car struck
another vehicle head-on. During your inspection of the interior of his vehicle, you would
MOST likely find:
A.deployed airbags.
B.steering wheel deformity.
C.starring of the windshield.
D.a crushed instrument panel. - <<ANSWER>>B.steering wheel deformity.
, Rationale: Blunt chest injuries during a motor vehicle crash typically occur when the
chest impacts the steering wheel. Therefore, your inspection of the vehicle's interior will
most likely reveal a deformed steering wheel.
5.An unrestrained driver collided with a bridge pillar. Upon inspection of the interior of
his vehicle, you note that the lower dashboard is crushed. During your assessment of
the patient, you will MOST likely encounter:
A.trauma to the pelvis.
B.blunt abdominal trauma.
C.a severe closed head injury.
D.penetrating thoracic trauma. - <<ANSWER>>A.trauma to the pelvis.
Rationale: Impact points are often obvious from a quick inspection of the vehicle's
interior. During a frontal collision, the unrestrained occupant's knees often impact the
lower dashboard. With this type of impact, energy is transferred from the knees to the
femurs, and then to the pelvis or hip.
abdominal trauma comes from striking steering wheel; severe closed head injury comes
from striking windshield; penetarting thoracic trauma caused by flying debris, collisions
w parts of vehicle, or other movable objects
6.Whiplash injuries are MOST common following _________ impacts.
A.rear-end
B.rollover
C.frontal
D.lateral - <<ANSWER>>A.rear-end
Rationale: Whiplash injuries of the neck are a common occurrence following rear-end
collisions. As the vehicle is suddenly thrust forward, the occupant's head is thrust
backward. Properly positioned headrests can minimize the severity of whiplash injuries.
rollover typically causes LT injuries; frontal causes chest, head, abd, extremity injuries;
lateral should suspect lateral chest and abd injuries and pelvic injuries
7.Death from a rollover motor vehicle crash is MOST often secondary to:
A.crushing injuries.
B.airbag-related trauma.
C.multiple collisions to the interior of the car.
D.ejection of the patient from the motor vehicle. - <<ANSWER>>D.ejection of the
patient from the motor vehicle.
Rationale: Rollover crashes are the most unpredictable with regard to injuries sustained
by the patient. An unrestrained passenger may have struck multiple points within the
vehicle. However, the most life-threatening event in a rollover is ejection or partial
ejection of the patient from the vehicle.
