deformed steering wheel
which of the following injuries would MOST likely occur as a direct result of the third collision in a motor vehicle crash ?
if one or more occupants in the same vehicle are killed in a crash, the EMT should
suspect that all living occupants experienced the same serious trauma
the driver of a sport utility vehicle lost control and struck a utility pole head-on. the driver was killed instantly. the passenger, a young female, is conscious and alert and has several small abrasions and lacerations to her left forearm. treatment for the passenger should include
transport to a trauma center
air bags are designed to
decrease the severity of deceleration injuries
when caring for an occupant inside a motor vehicle equipped with an airbag that that did not deploy upon impact, it is MOST important to
remember that it could still deploy and seriously injure you.
when a driver is in a car equipped with an air bag, but is not wearing a seatbelt, he or she will MOST likely strike the ____ when the air bag deploys upon impact.
while en route to a major motor vehicle crash, an on-scene police officer advises you that a 6 year old male who was riding in the front seat is involved. he further states that a child was only wearing a lap belt and that the air bag deployed. on the basis of this information, you should be MOST suspicious that the child has experienced.
neck and facial injuries
evaluation of the interior of a crashed motor vehicle during extrication will allow the EMT to
identify contact points and predict potential injuries
the cervical spine is MOST protected from whiplash-type injuries when the
headrest is appropriately positioned
passengers who are seated in the rear of a vehicle and are wearing only lap belts have a higher incidence of injuries to the
thoracic and lumbar spine
approximately 25% of a sever injuries to the aorta occr during
a driver involved in a rollover motor vehicle crash will MOST likely experience serious injuries or death if he or she
is ejected or partially ejected
a small compacted car was involved in a rollover crash. as you are approaching the vehicle, you note that the roof is significantly collapsed. the patient, a 29 year old male, is complaining of severe pain in his neck and to the top of his head as well as numbness and tingling in his extremities. witnesses who removed the patient from the vehicle state that he was wearing his seatblet. what injury mechanism is MOST likely responsible for this patient's condition ?
compression of the head against the roof
when evaluating the mechanism of injury of a car versus pedestrian collision, you should first
approximate the speed of the vehicle that struck the pedestrian
a 15 year old female was struck by a small car while riding her bicycle. she was wearing a helmet and was thrown to the ground, striking her head. in addition to managing problems associated with airway, breathing, and circulation, it is MOST important for you to
stabilize her entire spine
which of the following patients has experienced the MOST significant fall ?
a 4'6" patient who fell 13'
a 12 year old male jumped approximately 12' from a tree and landed on his feet. he complains of pain to his lower back. what injury mechanism is MOST likely responsible for his back pain ?
energy transmission to the spine
factors that should be considered when assessing a patient who has fallen include all of the following, EXCEPT
the speed of the fall
when assessing an elderly patient who fell, it is important to remember that
osteoporosis can cause a fracture that may have resulted in the fall
which of the following statements regarding low energy penetrating injuries is correct?
the area of injury is usually close to the path the object took through the body.
internal injuries caused by gunshot wounds are difficult to predict because
the bullet may tumble or ricochet within the body
the phenomenon of pressure waves emanating from the bullet, causing damage remote from its path, is known as
a young male sustained a gunshot would to the abdomen during an altercation with a rival gang member. as your partner is assessing and managing his airway, you should control the obvious bleeding and then
assess for an exit wound
a 40 year old unrestrained female impacted the steering wheel of her vehicle with her chest when she hit a tree while traveling at 45 mph. she is conscious and alert. but is experiencing significant chest pain and shortlness of breath. which of the following injuries did this patient likely NOT experience
if a person is standing near a building that explodes, which of the following injuries would he or she MOST likely experience as a result of the pressure wave ?
during your assessment of a patient who experienced a blast injury, you note that he has a depressed are to the front of his skull. this injury MOST likely occurred
during the tertiary phase
hen assessing a patient who experienced a blast injury, it is important to remember that
primary blast injuries are the most easily overlooked.
signs of a pulmonary blast injury include
coughing up blood
when treating a patient who experienced a pulmonary blast injury, you should
avoid giving oxygen under positive preassure
which of the following interventions is the MOST critical to the outcome of a patient with multisystem trauma ?
rapid transport to a trauma center
following a blunt injury to the head, a 22 year old female is confused and complains of a severe headache and nausea. on the basis of these signs and symptoms, you should be MOST concerned with the possibility of
A 30 year old male sustained a stab wound to the neck when he was attacked outside a nightclub. During your assessment, you should be MOST alert for
potential airway compromise
while assessing a young male who was struck in the chest with a steel pipe, you note that his pulse is irregular. you should be MOST suspicious for
bruising of the heart muscle
according to the association of Air Medical Services (AAMS), you should consider air medical transport of a trauma patient if
traffic conditions hamper the ability to get the patient to a trauma center by ground within the ideal time frame for the best clinical outcome.
in contrast to a level 3 trauma center, a level 1 trauma center must
have a general surgeons that are in house 24 hours a day
your patient has a glasgow coma scale score of 13, a systolic blood pressure of 80 mm Hg, and a respiratory rate of 8 breaths/min, his Revised Trauma Score (RTS) is
During your assessment of a patient with a head injury, you note that he opens his eyes when you pinch his trapezius muscle, is mumbling, and has his arms cures in toward his chest. you should assign him a GCS score of
according to American College of Surgeons, an adult trauma patient meets level 1 criteria if he or she
has a GCS score of less than or equal to 8 with a mechanism attributed to trauma
