with Verified Answers & Rationales | Comprehensive EMS Board
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 28-year-old male was involved in a motorcycle crash at 45 mph. He was
wearing a helmet but was thrown 30 feet from the bike. He is unresponsive with
shallow respirations at 8 breaths/min. Which of the following should be your
priority action?
A. Apply a cervical collar
B. Open the airway using a jaw-thrust maneuver
C. Apply high-flow oxygen via nonrebreather
D. Assess for pelvic instability
Rationale: An unresponsive patient with shallow respirations requires immediate airway
management. The jaw-thrust maneuver is preferred when spinal injury is suspected.
Airway takes priority over all other interventions .
2. A 45-year-old male fell 25 feet from a scaffolding onto concrete. He is conscious
but confused. Which of the following findings would indicate the need for
immediate spinal motion restriction?
A. GCS of 14 with no neurological deficits
B. Neck pain with midline tenderness
C. Bilateral pedal pulses present
D. Absence of visible deformities
Rationale: Midline neck tenderness in the setting of a significant mechanism of injury (fall
>20 feet) requires spinal motion restriction. This finding indicates potential spinal injury .
,3. A 35-year-old female was struck by a car while crossing the street. She has a
deformed right thigh with an open fracture. She is screaming in pain. What is the
most appropriate initial treatment for the open fracture?
A. Apply a traction splint
B. Cover the wound with a sterile dressing and apply a splint
C. Irrigate the wound with sterile saline
D. Realign the fracture
Rationale: An open fracture should be covered with a sterile dressing to prevent
contamination. The extremity should be splinted in the position found. Irrigation and
realignment are not performed in the prehospital setting .
4. A 60-year-old male with a history of hypertension was involved in a rear-end
collision at low speed. He complains of chest pain but has no visible injuries. What
is the most likely cause of his chest pain?
A. Cardiac contusion
B. Myocardial infarction
C. Pulmonary contusion
D. Rib fracture
Rationale: Low-speed rear-end collisions are unlikely to cause significant chest trauma.
Chest pain in an older patient with hypertension should raise suspicion for a cardiac event,
especially with a low mechanism of injury .
5. A 22-year-old female was assaulted and struck in the face with a baseball bat.
Her assessment reveals bilateral periorbital ecchymosis and clear fluid draining
from her nose. What should you suspect?
A. Orbital fracture only
B. Basilar skull fracture
C. Maxillary fracture
D. Mandibular fracture
,Rationale: Periorbital ecchymosis (raccoon eyes) with clear fluid draining from the nose
(CSF rhinorrhea) indicates a basilar skull fracture. This is a sign of significant head trauma
and requires spinal precautions .
6. A 30-year-old male was stabbed in the right upper quadrant of the abdomen.
He is hypotensive and tachycardic. Which organ is most likely injured?
A. Spleen
B. Liver
C. Stomach
D. Kidney
Rationale: The right upper quadrant contains the liver. Penetrating trauma to this area
can cause liver laceration and hemorrhage. The spleen is in the left upper quadrant .
7. A 40-year-old male was involved in a high-speed MVC. His assessment reveals
paradoxical movement of the left chest wall. What is the most appropriate
treatment?
A. Needle decompression
B. Positive pressure ventilation
C. Occlusive dressing
D. Chest tube insertion
Rationale: Paradoxical movement indicates flail chest. Positive pressure ventilation helps
to splint the flail segment and improve ventilation. This is the preferred treatment for
respiratory distress from flail chest .
8. A 25-year-old female was struck in the chest with a baseball bat. She is
complaining of chest pain and is dyspneic. You note a large contusion over the
sternum. What should you suspect?
A. Cardiac tamponade
B. Myocardial contusion
, C. Aortic dissection
D. Pulmonary contusion
Rationale: Blunt trauma to the chest with a contusion over the sternum suggests
myocardial contusion. This can cause arrhythmias and cardiac dysfunction .
9. A 55-year-old male with a history of COPD was involved in a minor MVC. He is
complaining of shortness of breath but has no obvious injuries. What should you
consider?
A. Pneumothorax from the accident
B. COPD exacerbation triggered by stress
C. Rib fracture without visible signs
D. Pulmonary embolism
Rationale: Patients with COPD can experience exacerbations triggered by stress or minor
trauma. The mechanism is minor, so a medical cause for shortness of breath should be
considered .
10. A 32-year-old male was shot in the left chest. Your assessment reveals an
entrance wound but no exit wound. What should you suspect?
A. The bullet is still in the chest
B. The bullet has migrated to another location
C. The bullet is in the abdomen
D. The bullet exited through the back
Rationale: If there is no exit wound, the bullet remains in the body. It may have migrated,
but the priority is to identify all wounds. Multiple wounds should be assessed .
11. A 28-year-old male was in a motorcycle crash. He is complaining of severe
pelvic pain. You note instability on palpation. What is the most appropriate
treatment?
A. Immobilize on a long backboard
