Review
Pass your final clinical milestone assessment on the first attempt with this definitive
2026 West Coast EMT Block 4 practice exam bank containing 200 high-yield questions.
This comprehensive preparation guide features 100% verified answers and rigorous
field rationales covering EMS operations, hazardous materials mitigation, mass casualty
triage, pediatric resuscitation, and obstetrical emergencies. It is an indispensable study
tool for emergency medical technician students looking to clear their blocks, pass the
NREMT cognitive exam, and secure an A+ grade.
1. A 12-year-old male jumped approximately 12 feet 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?
A. Lateral impact to the spine
B. Secondary fall after the initial impact
C. Direct trauma to the spinal column
D. Energy transmission to the spine
Rationale: When a patient lands on their feet from a height, the force of impact is
transmitted axially through the skeletal system. This energy transmission travels up from
the heels through the lower extremities to the lower spine, which can cause compression
fractures of the vertebrae .
2. According to the American College of Surgeons Committee on Trauma (ACS-
COT), an adult trauma patient should be transported to the highest level of trauma
center if he or she:
A. Was involved in a motor vehicle crash in which another patient in the same vehicle
was killed
,B. Has a systolic blood pressure of less than 110 mm Hg or a heart rate greater
than 110 beats/min
C. Has a bleeding disorder or takes anticoagulant medications and has any blunt or
penetrating injury
D. Was involved in a motor vehicle crash with intrusion of greater than 12 inches
Rationale: Hypotension (SBP <110 mmHg) and tachycardia (HR >110 bpm) are indicators
of hemodynamic instability and potential shock. The ACS-COT criteria identify these as
high-risk findings that warrant transport to the highest level trauma center .
3. When the speed of a motor vehicle doubles, the amount of kinetic energy:
A. Is not affected
B. Doubles
C. Triples
D. Quadruples
Rationale: Kinetic energy is calculated as KE = ½mv². When speed doubles, the kinetic
energy increases by a factor of four (2² = 4). This is why higher speeds produce
significantly more severe injuries .
4. Which of the following destinations is most appropriate for a 41-year-old male
patient who was involved in a rollover motor vehicle collision and is unconscious
and unresponsive, assuming that travel times to each is equal?
A. A Level I or Level II trauma center
B. Only a Level I trauma center
C. A Level IV or Level III trauma center
D. Any designated trauma center is acceptable
Rationale: An unconscious patient involved in a rollover collision with significant
mechanism of injury requires the highest level of trauma care available. Level I and Level II
trauma centers provide comprehensive trauma services, including immediate surgical
intervention .
,5. When assessing a patient who experienced a blast injury, it is important to
remember that:
A. Solid organs usually rupture from the pressure wave
B. Secondary blast injuries are usually the least obvious
C. Primary blast injuries are the most easily overlooked
D. Primary blast injuries are typically the most obvious
Rationale: Primary blast injuries affect air-filled organs (lungs, ears, GI tract) due to the
pressure wave. These injuries may not have visible external signs and are often overlooked
during initial assessment, making them the most easily missed .
6. When assessing an elderly patient who fell, it is important to remember that:
A. Any fall in the elderly is considered to be high-energy trauma
B. Osteoporosis can cause a fracture as a result of a fall from a standing position
C. Bilateral hip fractures usually occur when an elderly person falls
D. Elderly patients who fall usually have a secondary head injury
Rationale: Osteoporosis weakens bones in elderly patients, making them susceptible to
fractures from low-energy mechanisms such as a fall from standing height. What might be
a minor mechanism in a younger patient can cause significant injury in an elderly
patient .
7. Which of the following findings would be LEAST suggestive of the presence of
high-energy trauma?
A. Intrusion into the vehicle
B. Dismounted seats
C. Steering wheel deformity
D. Deployment of the air bag
Rationale: Airbag deployment, while indicating a significant impact, is designed to protect
the occupant. In contrast, vehicle intrusion, dismounted seats, and steering wheel
deformity indicate that the vehicle structure was compromised and energy was transferred
to the occupant, suggesting more severe injury potential .
, 8. Following blunt trauma to the abdomen, a 21-year-old female complains of
diffuse abdominal pain and pain to the left shoulder. Your assessment reveals that
her abdomen is distended and tender to palpation. On the basis of these findings,
you should be MOST suspicious of injury to the:
A. Spleen
B. Gallbladder
C. Pancreas
D. Liver
Rationale: Pain to the left shoulder (Kehr's sign) is associated with splenic injury. The
spleen is located in the left upper quadrant and is the most commonly injured organ in
blunt abdominal trauma. Blood irritating the diaphragm can cause referred pain to the
shoulder .
9. Hypovolemic shock occurs when:
A. The patient's systolic blood pressure is less than 100 mm Hg
B. The clotting ability of the blood is enhanced
C. The body cannot compensate for rapid blood loss
D. At least 10% of the patient's blood volume is lost
Rationale: Hypovolemic shock develops when blood loss exceeds the body's compensatory
mechanisms. While the exact threshold varies, significant blood loss (typically >10-15% of
circulating volume) leads to inadequate tissue perfusion and the development of shock .
10. If applying a dressing to control the bleeding of a patient's arm, the EMT
should:
A. Apply direct pressure first
B. Use large or small gauze pads or dressings depending upon the size of the wound
C. Cover the entire wound, above and below, with the dressing
D. All of these answers are correct
Rationale: All of these actions are appropriate steps in wound care. Direct pressure is the
initial method for bleeding control. The appropriate dressing size should match the wound.
Covering the entire wound helps contain bleeding and prevent contamination .
