Why Sequence Matters: Introducing the ABCDE Framework

Airway Assessment and Cervical Spine ProtectionNext

The primary survey exists to catch and treat immediately life-threatening injuries in the order they kill: airway, breathing, circulation, disability, exposure. This lesson explains why the sequence is fixed rather than flexible, and why exam questions are written to penalize candidates who jump ahead to an obvious injury before ruling out earlier threats.

We walk through why a visibly deformed limb is never the first priority when airway or breathing hasn't been confirmed, and how the exam tests this reasoning with distractor answers designed to tempt you toward the dramatic-but-lower-priority finding.
