A nurse is caring for an unconscious 40-year-old client who was admitted following a motorcycle accident. Which nursing action should be the nurse's first priority?

Priority Setting in Trauma Nursing: The ABC Principle

When caring for an unconscious client following a motorcycle accident, the nurse must apply the ABC (Airway, Breathing, Circulation) priority-setting framework. This systematic approach, foundational to both prehospital and emergency department trauma care, dictates that interventions addressing immediate threats to life take precedence over detailed assessments or secondary interventions.

Why Airway Takes Precedence Over Neurological Assessment

In the unconscious trauma patient, loss of pharyngeal muscle tone and impaired protective reflexes create an immediate risk of airway obstruction. The tongue can fall posteriorly against the posterior pharyngeal wall, and the absence of a gag reflex means the patient cannot clear secretions, blood, or foreign material. Apnoea—the cessation of breathing—is identified in trauma literature as one of the most critical and potentially reversible contributors to early mortality, capable of causing hypoxic brain injury within minutes if not corrected ^[1].

Assessing airway patency and intervening to maintain it directly addresses this time-sensitive threat. Without a patent airway, oxygen delivery to all tissues, including the brain, ceases. This means that performing a neurological assessment using the Glasgow Coma Scale (option 1) or obtaining vital signs (option 4) before securing the airway would delay the most critical, life-saving intervention. The data gathered from those assessments would be clinically meaningless if the patient is not being oxygenated.

The Role of Aspiration Prevention and Evidence-Based Sequencing

Inserting a nasogastric tube (option 2) is an important intervention to decompress the stomach and reduce the risk of aspiration of gastric contents. However, the evidence from trauma quality improvement research demonstrates that adherence to a structured checklist—which prioritizes airway and breathing assessment immediately upon patient arrival—significantly reduces emergency treatment time and improves care efficiency . The checklist approach reinforces that airway patency must be established first; gastric decompression is a secondary step that follows, not precedes, the stabilization of the airway and breathing.

Furthermore, best-practice evidence for managing hypoxemia in perioperative and acute care settings emphasizes that the initial and continuous priority is a focused respiratory assessment, including immediate evaluation of airway patency, breathing pattern, and oxygen saturation . This evidence base consistently ranks airway security above all other nursing actions in the sequence of care.

Applying the Trauma Care Framework

Guideline syntheses for early trauma and burn injury care in resource-limited settings universally reinforce the Airway with cervical spine protection as the first step in the primary survey . The mechanism of injury—a motorcycle accident—carries a high risk for cervical spine injury, making the jaw-thrust maneuver the appropriate method for opening the airway while maintaining spinal immobilization. The nurse's first priority is therefore to visually inspect the oropharynx for obstruction, suction as needed, and perform a jaw-thrust to establish patency, ensuring that the fundamental requirement for oxygenation is met before proceeding to any other component of the trauma assessment. The systematic prioritization of airway intervention is not merely a procedural step but a direct response to the pathophysiology of rapid hypoxic injury in the apnoeic or obstructed trauma patient ^[1].
