AEMCA Practice Exam

Which mechanism of injury (MOI) should be considered for spinal motion restriction (SMR)?

1. Electrocution and dehydration

2. Trauma with head or neck pain and submersion

3. Simple falls and minor sprains

4. Sports injuries only

The correct answer is: Trauma with head or neck pain and submersion

Considering spinal motion restriction (SMR) is essential when assessing mechanisms of injury (MOI) that could potentially lead to spinal cord injury or compromise the spine's integrity. Trauma with head or neck pain, in particular, raises significant concern, as it indicates that the spinal structures may have been affected. The presence of head or neck pain suggests that there may be damage or instability in these regions, which necessitates careful handling to prevent further injury. Additionally, the mention of submersion adds another layer of risk, as drowning incidents or near-drowning can lead to spinal injuries from impacts or forceful entry into water. This combination of trauma indicators requires that spinal movement be restricted to protect the patient during evaluation and transport. In contrast, simple falls and minor sprains typically do not present serious risks for spinal injuries and often do not warrant SMR. Likewise, sports injuries may be too broad of a category, as not all sports-related injuries imply significant spinal risk. Electrocution and dehydration also represent different medical concerns that do not inherently suggest spinal trauma in the absence of other indicators. Thus, focusing on the critical factors of trauma coupled with head or neck symptoms and the potential for injuries related to submersion solidifies the need for SMR in
