  • Why are extremity wounds above the elbow or knee more concerning?
    More likely to involve significant vascular injury and hemorrhage
  • What is the target time for primary and secondary stabilization, packaging, and transport initiation?
    Under 10 minutes
  • What is a key feature of a Level I trauma center?
    Is a regional center prepared to handle all specialty trauma 24/7
  • Which of the following is essential for proper hospital care of serious trauma patients?
    Immediate availability of skilled surgical intervention
  • In the up-and-over pathway of frontal impacts, which injury is most likely?
    Facial fractures and cervical spine injury
  • A Level III trauma center is typically:
    A community hospital with staff training and resources for trauma
  • Why do solid organs experience greater damage from cavitation?
    They are dense but not resilient and transmit pressure well
  • What formula defines kinetic energy?
    KE = (mass × velocity²) ÷ 2
  • What causes compartment syndrome to develop?
    Muscle swelling within fascial compartments that cannot expand
  • What was the significance of the Trauma Care Systems Planning and Development Act of 1990?
    It provided funding, guidelines, and state leadership for trauma systems
  • Under what circumstance should EMS consider removing an impaled object?
    If it's interfering with airway management or CPR
  • What led to the development of today’s trauma care system?
    Investigation of death toll on U.S. highways
  • Which of the following is a common cause of blunt trauma?
    Falls, motor vehicle collisions, or sports injuries
  • Why is field recognition of compartment syndrome difficult?
    Signs often develop gradually and may not be evident prehospital
  • Which formula correctly represents kinetic energy?
    [Mass × velocity²] ÷ 2
  • What is the purpose of a trauma registry?
    Collect standardized data for system analysis and improvement
  • Which tissue type generally limits cavitational damage due to its elasticity and density?
    Connective tissue (muscle, tendons, ligaments, skin)
  • What is a pressure wave in the context of penetrating trauma?
    Outward and forward movement of tissue caused by high-speed projectile impact
  • Which of the following injuries are considered pressure wave-related?
    Ear drum rupture, bowel injury, lung damage
  • What are the components considered in the trauma triage criteria?
    MOI, age, vital signs, anatomy of injury, GCS
  • Which of the following is an example of a trauma intervention?
    Safer vehicle design, Gun safety education, Improved EMS response
  • Which of the following best describes quarternary blast injuries?
    Any other injuries like burns, toxic exposures, or worsening of chronic illness
  • Why are neck wounds particularly dangerous?
    Small space contains airway, spinal cord, vessels—risking airway compromise, bleeding, and air embolism
  • If intubation is impossible due to facial trauma and airway compromise, what procedure may be indicated?
    Percutaneous cricothyrotomy
  • What is the primary role of a Level IV trauma center?
    Stabilize patients before transport to a higher-level center
  • What is a teachable moment in trauma care?
    When a near-harm event is used to encourage safer behavior
  • In the down-and-under pathway, what injuries may occur?
    Knee, femur, hip dislocations; chest and vascular injuries
  • Why do some bullets tumble or yaw inside soft tissue?
    Their center of mass is farther from the leading edge, especially in rifle rounds
  • When assessing gunshot wounds in the field, EMS should:
    Describe wounds by appearance and location, avoiding labels like entrance/exit
  • Which type of impact happens when the occupant is struck by loose items within the vehicle?
    Secondary collision
  • For a patient suspended for more than 30 minutes, EMS should consider:
    Placing the patient in a seated position with upper body support to slow toxin return
  • : What did studies in the 1960s reveal about crash victims?
    They experienced injuries and lacked access to organized, definitive care
  • What best describes a Level II trauma center?
    Has high commitment to trauma care but may transfer most serious cases
  • What defines a secondary impact in penetrating trauma?
    Bullet striking another object (e.g., glass, clothing) before or during impact with the body
  • What is the best way to reduce trauma overall?
    Prevention
  • In blunt trauma, which type of organ is at greater risk of injury?
    Solid organs
  • How does body armor reduce penetrating trauma?
    It spreads bullet energy across a large area, reducing penetration but possibly causing blunt trauma
  • What does true QI avoid doing?
    Blaming individual providers
  • How many levels of trauma centers are recognized in the current trauma system model?
    4
  • How much blood volume can pool in the legs during prolonged suspension?
    Approximately 20%
  • What is resiliency in the context of tissue damage?
    Tissue’s connective strength and elasticity influencing damage severity
  • Which best describes the primary objective of a Quality Improvement (QI) program within a trauma care system?
    Enhancing patient outcomes by continuously evaluating system-wide clinical performance
  • Which national organization has identified key MOIs predictive of trauma center need?
    Centers for Disease Control and Prevention (CDC)
  • What is the goal of the Golden Period in trauma care?
    One-hour window from incident to surgery
  • A shear injury most often affects:
    Organs and tissues at attachment points
  • What is the most common type of vehicle impact?
    Frontal
  • Why do shotgun wadding materials increase risk of infection?
    They may penetrate the wound and introduce contaminants
  • What causes tissue damage in blunt trauma?
    Energy forces transferred without penetration
  • A bullet’s profile refers to:
    The diameter of the bullet (caliber) facing the target
  • Which of the following best describes the zone of injury?
    Tissue around the wound that is crushed, torn, and susceptible to infection and slow healing
  • What is the goal of Quality Improvement (QI) in trauma systems?
    Improving patient care by studying system performance
