WEST COAST EMT BLOCK 4 EXAM COMPLETE COURSE NEWEST ACTUAL
EXAM/NEWEST UPDATE 2026!!!
Question 1
The cervical spine is MOST protected from whiplash-type injuries when the:
A) rear end of the vehicle is initially struck.
B) headrest is appropriately positioned.
C) patient tenses up at the time of impact.
D) airbag correctly deploys upon impact.
E) seatbelt is worn as a lap belt only.
Correct Answer: B) headrest is appropriately positioned.
Rationale: Whiplash injuries occur during rear-end collisions when the vehicle accelerates
forward, pushing the torso forward while the head lags behind due to inertia, causing acute
hyperextension of the neck. An appropriately positioned headrest directly behind the
occiput catches the head and stops excessive backward movement, preventing hyper-
extension and protecting the cervical spine.
Question 2
Approximately 25% of severe injuries to the aorta occur during:
A) rear-end collisions.
B) rollover collisions.
C) lateral collisions.
D) frontal collisions.
E) rotational collisions.
Correct Answer: C) lateral collisions.
Rationale: In lateral (T-bone) collisions, the vehicle and the occupant's thorax are subjected
to sudden lateral deceleration and displacement. The aorta is anchored at the ligamentum
arteriosum, while the aortic arch and descending aorta are relatively free to move. This
lateral shearing force tears the aorta, accounting for roughly one out of four severe
traumatic aortic disruptions.
Question 3
Evaluation of the interior of a crashed motor vehicle during extrication will allow the EMT to:
A) determine the vehicle's speed at the time of impact.
B) identify contact points and predict potential injuries.
C) recognize if the driver hit the brakes before impact.
D) assess the severity of the third collision of the crash.
E) estimate the exact horsepower generated by the engine.
Correct Answer: B) identify contact points and predict potential injuries.
Rationale: Evaluating vehicle interior damage (such as a deformed steering wheel, spidered
windshield, knee bolster indentations, or crushed door panels) reveals points of secondary
collision where the patient's body struck the vehicle. This helps the EMT anticipate specific
underlying skeletal and visceral injuries.

Question 4
Which of the following interventions is the MOST critical to the outcome of a patient with
multisystem trauma?
A) Elevation of the lower extremities
B) Intravenous fluid administration
C) Early administration of oxygen
D) Rapid transport to a trauma center
E) Thorough secondary survey on scene
Correct Answer: D) Rapid transport to a trauma center.
Rationale: Definitive care for severe multisystem trauma and non-compressible internal
hemorrhage is emergent surgical repair in an operating room. On-scene time should be
limited to 10 minutes or less (the "platinum ten minutes"), focusing on immediate life
threats, spinal precautions, and rapid transport to a designated trauma center.
Question 5
When evaluating the mechanism of injury of a car versus pedestrian collision, you should first:
A) determine if the patient was propelled away from the vehicle.
B) approximate the speed of the vehicle that struck the pedestrian.
C) determine if the patient was struck and pulled under the vehicle.
D) evaluate the vehicle that struck the patient for structural damage.
E) establish if the patient's shoes were knocked off during impact.
Correct Answer: B) approximate the speed of the vehicle that struck the pedestrian.
Rationale: The initial speed of the striking vehicle dictates the kinetic energy transferred to
the pedestrian (

𝐾𝐸 = 𝑚𝑣 2
2
). Estimating vehicle speed provides the primary context for the severity of subsequent
impacts, including initial bumper contact, windshield/hood impact, and ground impact.
Question 6
If one or more occupants in the same vehicle are killed in a crash, the EMT should:
A) transport the survivors only if they have injuries or complain of pain.
B) suspect that all living occupants experienced the same serious trauma.
C) allow the survivors to refuse transport if they have no obvious injuries.
D) rapidly assess only the survivors who have experienced obvious trauma.
E) assume the survivors had structural barriers protecting them.
Correct Answer: B) suspect that all living occupants experienced the same serious trauma.
Rationale: The death of an occupant in the same passenger compartment indicates that
massive kinetic energy was transferred to the vehicle. All surviving occupants share this
