What is the primary survey sequence used in trauma assessment?

• A. Airway, Breathing, Circulation, Disability, Exposure (and environmental control).
• B. Circulation, Airway, Breathing, Disability, Exposure
• C. Airway, Circulation, Breathing, Exposure, Disability
• D. Breathing, Airway, Circulation, Disability, Exposure

Answer: (A)

In trauma care, the first priority is a sequence that rapidly identifies and treats the most dangerous threats to life. That order begins with securing an open airway and protecting the spine, because without a patent airway the patient cannot be adequately ventilated or oxygenated, and brain injury or hypoxia can progress extremely quickly. Once the airway is ensured, the next focus is breathing to verify that the patient is actually ventilating and receiving enough oxygen; if breathing is compromised, you address ventilation and oxygen delivery immediately. After airway and breathing are stabilized, the next step is circulation. This involves checking for life-threatening bleeding and ensuring adequate perfusion; controlling external hemorrhage and establishing IV access are key, since shock from blood loss can rapidly worsen outcomes if not promptly managed. Following circulation, you assess disability, which is a quick check of the patient’s neurologic status using a tool like the Glasgow Coma Scale or the AVPU scale to establish a baseline and detect any deteriorating brain function. The final component is exposure, where you fully inspect the body for hidden injuries while taking steps to prevent hypothermia. This step ensures no injury is missed, but it comes after the most pressing airway, breathing, and circulation issues have been addressed. Other sequences fail because they risk delaying critical actions (for example, addressing circulation before confirming an airway, or exposing the patient before airway and breathing are secured), which could allow life threats to go untreated for too long.
