EXAM/NEWEST UPDATE 2026!!!
Question 1
According to the American College of Surgeons Committee on Trauma (ACS-COT), which of
the following adult trauma patients should be transported to the highest level of trauma center?
A) A patient involved in a motor vehicle crash with one fatality in the vehicle.
B) A patient with a systolic blood pressure of 105 mm Hg.
C) A patient taking anticoagulant medications with a minor skin abrasion.
D) A patient with a Glasgow Coma Scale (GCS) score of 13 or less due to trauma.
E) A patient who fell from a height of 5 feet.
Correct Answer: D) A patient with a Glasgow Coma Scale (GCS) score of 13 or less due to
trauma.
Rationale: The ACS-COT identifies a GCS of 13 or less as a physiological criterion for
triage to the highest level of trauma center. While the other factors (Option A, C) are
important indicators in the "Index of Suspicion," a GCS ≤ 13 represents a significant
alteration in neurological status that requires immediate neurosurgical and trauma team
intervention.
Question 2
According to the Association of Air Medical Services, which factor is a primary consideration
for requesting air medical transport?
A) The patient is in cardiac arrest and requires immediate stabilization.
B) Ground transport will take the ambulance out of service for over 30 minutes.
C) Traffic conditions hamper the ability to reach a trauma center within the "Golden Hour."
D) The patient has minor injuries but was involved in a crash where another occupant died.
E) The nearest ALS ground unit is 3 minutes away.
Correct Answer: C) Traffic conditions hamper the ability to reach a trauma center within
the "Golden Hour."
Rationale: Air medical transport is considered when the time saved by air transport
compared to ground transport is clinically significant for the patient's outcome. Hampered
traffic conditions or long distances that prevent timely ground arrival at a trauma center
are valid criteria for flight activation.
Question 3
Which collision type is responsible for approximately 25% of all severe injuries to the aorta?
A) Frontal collisions
B) Rear-end collisions
C) Lateral (Side-impact) collisions
D) Rollover collisions
E) Low-speed rotational collisions
Correct Answer: C) Lateral (Side-impact) collisions
Rationale: Lateral collisions, often called "T-bone" impacts, result in approximately 25% of
, 2
all severe aortic injuries. The mechanism involves the lateral displacement of the heart
while the aorta is fixed by the ligamentum arteriosum, leading to shearing forces and
potential rupture.
Question 4
A 22-year-old female presents with confusion, a severe headache, and nausea after a blunt head
injury. Which underlying condition is the MOST likely cause of these symptoms?
A) A simple skull fracture
B) A minor concussion
C) Intracranial bleeding
D) Acute spinal cord injury
E) Post-traumatic stress
Correct Answer: C) Intracranial bleeding
Rationale: The combination of confusion (altered mental status), severe headache, and
nausea/vomiting following head trauma is highly suggestive of increased intracranial
pressure (ICP), which is most often caused by intracranial hemorrhage (epidural,
subdural, or intracerebral).
Question 5
In the physics of trauma, how is "Work" defined?
A) Mass times velocity
B) Force acting over a distance
C) Half of the mass times velocity squared
D) Energy that is stored in an object
E) Acceleration divided by mass
Correct Answer: B) Force acting over a distance
Rationale: Work is defined as force acting over a distance. In a traumatic mechanism, work
is the energy transfer required to damage or deform tissues or objects (such as the bending
of a steering wheel or the crushing of a chest).
Question 6
Which of the following defines the "Index of Suspicion"?
A) The predictable pattern of injury following a fall.
B) The detection of obvious, life-threatening external injuries.
C) Awareness and concern for potentially serious underlying injuries based on the MOI.
D) The mathematical calculation of kinetic energy.
E) The legal documentation of a trauma scene.
Correct Answer: C) Awareness and concern for potentially serious underlying injuries based
on the MOI.
Rationale: The index of suspicion is the EMT’s ability to anticipate internal injuries that
, 3
may not be immediately obvious, based on the severity of the Mechanism of Injury (MOI).
It guides the EMT to perform a more thorough assessment and prioritize rapid transport.
Question 7
During a blast injury, which type of injury is most frequently overlooked by medical providers?
A) Secondary blast injuries (shrapnel)
B) Tertiary blast injuries (being thrown)
C) Primary blast injuries (pressure wave)
D) Quaternary blast injuries (burns/crush)
E) Open soft tissue lacerations
Correct Answer: C) Primary blast injuries (pressure wave)
Rationale: Primary blast injuries are caused by the pressure wave itself and often affect gas-
filled organs (lungs, ears, GI tract). Because there may be no external signs of trauma,
these internal pressure injuries are the most easily overlooked compared to shrapnel or
blunt force injuries.
Question 8
When evaluating a fall involving an elderly patient, the EMT must remember that:
A) Only falls from over 15 feet are considered high-energy trauma.
B) Osteoporosis can lead to fractures from a simple fall from a standing position.
C) Bilateral hip fractures are a requirement for a high index of suspicion.
D) Elderly patients rarely experience head injuries during a fall.
E) All geriatric falls require air medical transport.
Correct Answer: B) Osteoporosis can lead to fractures from a simple fall from a standing
position.
Rationale: Osteoporosis reduces bone density, making the skeleton fragile. In geriatric
patients, a "low-energy" fall from a standing height is often enough to cause a hip or spinal
fracture, whereas the same fall might not injure a younger adult.
Question 9
If the speed of a motor vehicle doubles (e.g., from 30 mph to 60 mph), how much does the
kinetic energy increase?
A) The kinetic energy doubles.
B) The kinetic energy triples.
C) The kinetic energy quadruples.
D) The kinetic energy remains the same.
E) The kinetic energy increases tenfold.
Correct Answer: C) The kinetic energy quadruples.
Rationale: The formula for kinetic energy is
𝐾𝐸 = 1/2𝑚𝑣 2
, 4
. Because velocity is squared, doubling the speed increases the energy by a factor of four (
22 = 4
). This explains why high-speed crashes are significantly more lethal.
Question 10
A 41-year-old male is unconscious and unresponsive after a rollover crash. Assuming equal
travel times, what is the most appropriate destination?
A) A Level III trauma center
B) A Level I or Level II trauma center
C) A community hospital with no trauma designation
D) A Level IV trauma center
E) Any hospital with an open emergency room
Correct Answer: B) A Level I or Level II trauma center
Rationale: Unconscious/unresponsive patients meet high-priority physiological criteria.
Level I and II centers have the most resources, including 24-hour surgical availability,
which is required for critical multisystem trauma management.
Question 11
Which of the following is LEAST suggestive of high-energy trauma in a vehicle crash?
A) Intrusion into the passenger compartment
B) Deformation of the steering wheel
C) Dismounted seats
D) Deployment of the air bag
E) Death of another occupant in the vehicle
Correct Answer: D) Deployment of the air bag
Rationale: Airbags can deploy at relatively low speeds (8-14 mph) during minor impacts.
While they signal an impact, they do not necessarily indicate the massive energy transfer
seen with cabin intrusion, steering wheel deformity, or seat displacement.
Question 12
Which injury is most likely a direct result of the "third collision" in a motor vehicle crash?
A) Flail chest
B) Facial lacerations
C) Aortic rupture
D) Femur fracture
E) Pelvic instability
Correct Answer: C) Aortic rupture
Rationale: The three collisions are: 1. Vehicle vs Object, 2. Occupant vs Vehicle Interior, 3.
Organs vs Body Cavity Walls. Aortic rupture occurs during the third collision when the
