Trauma Emergencies and Spinal Motion Restriction - NREMT EMT Level

1. Which action is correct when vomiting occurs in a patient under SMR precautions?

   Suction and roll the patient as a unit to protect the airway. Rolling as a unit with suction prevents aspiration while preserving spinal precautions during emesis.

2. What is the correct action if jaw-thrust does not open the airway adequately?

   Use head-tilt chin-lift to open the airway. Airway patency takes precedence over spinal precautions when initial maneuvers fail, as hypoxia is immediately life-threatening.

3. Identify the correct action for an unresponsive trauma patient found prone with suspected spine injury.

   Log-roll to supine as a unit while maintaining manual in-line stabilization. Log-rolling maintains spinal alignment during repositioning for assessment and airway management in prone patients.

4. What is the correct order for securing a patient to a long backboard for SMR?

   Torso first, then pelvis/legs, then head last. Securing the torso first stabilizes the body's core, allowing precise head immobilization last.

5. What is the immediate EMT treatment priority for suspected neurogenic shock?

   Airway/ventilation, oxygen, prevent heat loss, rapid transport. Supportive measures address vasodilation and hypothermia while expediting advanced care for vasopressor needs.

6. Which action is correct if a patient resists neutral alignment or has increased pain?

   Stop and immobilize in the position found. Forcing alignment risks worsening injury, so immobilization in the current position protects the spine.

7. Which shock type is most likely when hypotension is present with tachycardia after trauma?

   Hemorrhagic shock. Tachycardia compensates for blood loss in hypovolemic states, unlike the bradycardia in neurogenic shock.

8. What is the preferred neutral position for SMR of the head and neck?

   Head aligned with torso in neutral, eyes looking forward. Neutral alignment minimizes pressure on the spinal cord and maintains anatomical integrity during immobilization.

9. What finding most strongly indicates a high-energy mechanism of injury (MOI)?

   Significant vehicle intrusion, ejection, death in same vehicle, or high-speed impact. These indicators reflect substantial force transfer likely to cause severe internal injuries in motor vehicle collisions.

10. Identify the correct action when a helmeted athlete is breathing adequately and helmet fits well.

    Leave helmet in place and apply SMR; remove facemask for airway access. A well-fitting helmet provides inherent stabilization, and facemask removal ensures airway access without unnecessary removal risks.

11. Which patient presentation requires immediate spinal motion restriction (SMR) consideration?

    Neck/back pain, neuro deficits, altered mental status, or high-risk MOI. These signs suggest potential spinal instability, necessitating restriction to avoid exacerbating cord injury.

12. What is the primary reason for SMR in trauma care?

    To reduce movement that could worsen spinal cord injury. Limiting motion prevents secondary injury to an unstable spine from excessive flexion, extension, or rotation.

13. What is the best definition of spinal shock in the trauma patient?

    Temporary loss of spinal reflexes and motor/sensory function below injury. Spinal shock results from acute disruption of neural transmission, leading to flaccid paralysis until reflexes recover.

14. What is the best description of a "distracting injury" affecting SMR decisions?

    A painful injury that can mask neck or back pain. Distracting injuries divert attention from spinal symptoms, potentially leading to missed instability in assessments.

15. Which device is commonly used for moving a supine patient while maintaining SMR?

    Long backboard used as a transfer device. Backboards provide rigid support for spinal alignment during patient movement and transport.

16. What is the best immediate action for a trauma patient with suspected spine injury and inadequate breathing?

    Provide ventilations with BVM while maintaining manual in-line stabilization. Ventilation support addresses respiratory failure immediately, with stabilization preventing further spinal compromise.

17. What is the best initial action when you suspect an unstable cervical spine injury?

    Manual in-line stabilization of the head and neck. Manual stabilization prevents further spinal cord damage by minimizing movement until full immobilization can be applied.

18. What is the EMT priority sequence for trauma patient care?

    Scene safety, BSI, primary assessment, transport decision, secondary assessment. This sequence prioritizes immediate safety and life-threatening issues before detailed evaluation to optimize trauma patient outcomes.

19. Which airway maneuver is preferred when spinal injury is suspected?

    Jaw-thrust maneuver. Jaw-thrust avoids cervical extension, reducing risk of aggravating spinal injuries while opening the airway.

20. Which device is typically used for SMR of a seated patient in a vehicle?

    Short extrication device (KED-type device). KED devices secure the spine while allowing safe extrication from confined spaces like vehicles.

21. What is the most important life threat to manage before completing SMR?

    Airway and ventilation problems. Airway compromise is a critical ABC priority that must be resolved before spinal procedures to ensure oxygenation.

22. What is the hallmark vital-sign pattern of neurogenic shock?

    Hypotension with bradycardia and warm, dry skin. Loss of sympathetic innervation causes vasodilation and unopposed parasympathetic effects, differing from other shock types.

23. Which action is correct if a helmet prevents access to the airway or does not fit securely?

    Remove the helmet using a two-person technique with SMR maintained. Poor fit or airway obstruction necessitates removal to prioritize breathing while preserving spinal alignment.

24. Which assessment finding most strongly suggests spinal cord involvement?

    Numbness, weakness, or paralysis in extremities. These symptoms indicate direct spinal cord compromise, distinguishing from peripheral or musculoskeletal issues.

25. What is the correct order for releasing straps from a long backboard after arrival?

    Head first, then pelvis/legs, then torso last. Releasing in reverse order maintains torso stability while manual stabilization is reapplied to the head.
