NREMT: EMT Level › Trauma Emergencies and Spinal Motion Restriction
When performing a log roll to place a trauma patient on a backboard, what is the minimum number of personnel required?
Two people: one to control the head and neck, one to roll the body
Four people: one for head control, one each for torso and pelvis, one for legs
Three people: one for head control, one for torso, one for legs and pelvis
Five people: one for head control, two for torso, one for pelvis, one for legs
Explanation
The minimum safe number for a log roll is four people: one person maintains manual head and neck stabilization and directs the roll, while three others control different body segments (typically torso, pelvis, and legs) to maintain spinal alignment during the maneuver. Two people cannot adequately control all body segments. Three people may be insufficient for larger patients or when precise control is needed. Five people may be used for very large patients or complex situations, but four is the standard minimum for safe log rolling technique.
Which mechanism of injury would MOST likely require spinal motion restriction according to current EMT protocols?
A patient who slipped on ice and fell backward onto their buttocks
A patient who fell from a standing height and landed on their feet
A motor vehicle collision with significant vehicle damage and an unconscious patient
A pedestrian who was struck by a bicycle traveling at low speed
Explanation
A motor vehicle collision with significant vehicle damage and an unconscious patient presents the highest risk for spinal injury due to the mechanism (high-energy trauma) and the inability to assess the patient's neurological status or obtain reliable history. Current protocols emphasize spinal motion restriction based on mechanism, altered mental status, and clinical findings. Falls from standing height typically do not generate enough force to cause spinal injury. Simple falls onto buttocks and low-speed bicycle strikes generally involve lower energy mechanisms with less spinal injury risk.
What is the correct sequence for applying spinal motion restriction devices to a trauma patient?
Manual stabilization, cervical collar, log roll to backboard, then secure torso before head
Cervical collar, then long backboard, followed by head immobilization device and straps
Long backboard positioning, cervical collar application, then head blocks and body straps
Head immobilization first, then cervical collar, followed by body positioning and final securing
Explanation
The correct sequence begins with manual in-line stabilization, followed by cervical collar application, log rolling the patient onto the backboard while maintaining spinal alignment, then securing the torso first and head last. This sequence ensures continuous spinal protection while allowing proper positioning. The torso is secured before the head to prevent movement during final positioning. Starting with the backboard or head immobilization devices before manual stabilization would leave the spine unprotected during initial movements.
When assessing a trauma patient for spinal motion restriction, which finding would be MOST concerning for cervical spine injury?
Chest pain that worsens with movement but normal sensation in all extremities
Lower back pain that radiates down one leg with normal upper body sensation
Patient reports sharp pain in the shoulder blade area that increases with deep breathing
Numbness and weakness in both hands with normal sensation in the arms and legs
Explanation
Numbness and weakness in both hands with normal arm and leg sensation suggests a specific cervical spine injury affecting the central cord, which is most concerning for cervical spine pathology. This pattern indicates damage to the central portion of the spinal cord in the cervical region. Shoulder blade pain with breathing suggests rib or lung injury. Lower back pain radiating down one leg suggests lumbar spine or nerve root issues. Chest pain with movement could indicate rib fractures or chest wall injury but doesn't specifically suggest cervical spine involvement.
During transport of a patient with spinal motion restriction, you notice the patient's level of consciousness is decreasing. What should be your immediate concern?
The backboard position is causing decreased venous return and subsequent hypotension
The spinal injury is progressing and causing increased neurological damage to the brain
The cervical collar is too tight and is restricting blood flow to the brain
Possible airway compromise or other life threat that may require repositioning for management
Explanation
Decreasing level of consciousness during transport is a life-threatening change that may indicate airway compromise, shock, or other critical conditions that could require immediate intervention, potentially including repositioning for airway management. Life threats take priority over spinal precautions. While spinal injuries can cause neurological changes, acute deterioration in consciousness is more likely due to airway, breathing, or circulation problems. Backboard positioning rarely causes significant hemodynamic changes in healthy patients. A properly fitted cervical collar should not restrict cerebral blood flow.
What is the primary reason for securing a patient's torso to the backboard before securing the head?
Securing the head first can cause airway obstruction when the torso is subsequently positioned
Torso movement during securing can cause spinal movement if the head is already fixed
Patient comfort is better maintained when the larger body mass is secured before the head
The torso straps provide the majority of spinal stabilization and must be tight first
Explanation
The torso should be secured before the head because movement of the larger body mass during securing can cause unwanted spinal movement if the head is already rigidly fixed in place. By securing the torso first, the spine is stabilized in proper alignment, then the head is secured to maintain that position. While torso straps are important, they don't provide the 'majority' of stabilization - the entire system works together. Head immobilization typically doesn't cause airway obstruction when properly applied. Patient comfort, while important, is not the primary safety consideration for this sequencing.
During spinal immobilization, proper head positioning requires the head to be placed in which position?
Flexed forward to counteract the natural curve of the cervical spine on the flat backboard
Neutral anatomical position aligned with the rest of the spinal column without extension or flexion
Slightly extended to open the airway and maintain cervical lordosis during transport
Rotated slightly to the patient's most comfortable position to prevent muscle spasm during transport
Explanation
The head should be maintained in a neutral anatomical position, aligned with the rest of the spinal column, without flexion, extension, or rotation. This position maintains the normal anatomical relationships and minimizes stress on potentially injured spinal structures. Extension can worsen certain types of cervical injuries and may compromise the airway in some patients. Flexion can also worsen injuries and is not physiologically neutral. Any rotation from the neutral position can cause additional injury to an unstable cervical spine.
How should you position this patient for spinal motion restriction?
Left lateral recovery position to prevent aspiration while maintaining spinal alignment
Sitting position on the stretcher with cervical collar to reduce respiratory compromise
Prone position as found to avoid unnecessary movement of the potentially injured spine
Supine on a long backboard with cervical collar and head blocks for stabilization
Explanation
The supine position on a long backboard with full spinal immobilization is appropriate for this patient with suspected cervical spine injury and neurological symptoms. The diving mechanism and neurological findings (numbness and tingling in arms) strongly suggest cervical spine injury. The lateral recovery position is not appropriate for conscious patients with suspected spinal injury. Sitting position doesn't provide adequate spinal restriction. Leaving the patient prone would compromise airway management and assessment capabilities.
Based on current selective spinal immobilization criteria, what is the most appropriate approach?
Transport in a position of comfort with continuous monitoring for development of symptoms
Spinal motion restriction may not be necessary if the patient meets all low-risk criteria
Full spinal immobilization is required due to the motor vehicle collision mechanism regardless of symptoms
Apply a cervical collar for comfort but allow the patient to ambulate to the stretcher
Explanation
This scenario describes a patient who may meet criteria for selective spinal immobilization: alert and oriented, no neck/back pain, normal neurological exam, low-risk mechanism (rear-end collision at low speed), and no distracting injuries. If all criteria are met per local protocols, spinal motion restriction may not be necessary. Not all motor vehicle collisions automatically require full immobilization under current evidence-based guidelines. Cervical collars should not be applied 'for comfort' when not medically indicated. Position of comfort alone is not an appropriate compromise when specific protocols exist for these decisions.
What additional assessment finding would MOST strongly indicate the need for spinal motion restriction?
Point tenderness is present over the cervical spinous processes when palpated gently
The patient has a history of previous neck injuries from sports activities in the past
The wrestling coach reports this type of throw rarely results in serious injuries to athletes
The patient reports the neck pain is mild and only occurs with extreme range of motion
Explanation
Point tenderness over the cervical spinous processes is a significant physical finding that suggests possible spinal injury, even when neurological function appears normal. This finding, combined with the mechanism and neck pain complaint, strongly indicates the need for spinal motion restriction. Previous injury history is relevant but not as immediately significant as current physical findings. Mild pain that occurs only with movement might actually support selective immobilization in some protocols. The coach's opinion about injury frequency is not medically relevant to the current patient's assessment.
