Which sequence best represents the initial assessment priority in emergency care?

• A. Airway, Breathing, Circulation, Disability, Exposure
• B. Airway, Circulation, Breathing, Disability, Exposure
• C. Breathing, Airway, Circulation, Disability, Exposure
• D. Disability, Exposure, Airway, Breathing, Circulation

Answer: (A)

Securing an open airway is the first priority in any emergency assessment because oxygen cannot reach the tissues if the airway is obstructed. If the airway isn’t patent, even perfect breathing or circulation efforts won’t prevent hypoxia, so the initial steps focus on airway management and protection of the spine if trauma is suspected. Once the airway is clear, evaluate breathing to ensure adequate ventilation and oxygen delivery. If breathing is inadequate or ineffective, provide appropriate support—oxygen, ventilation assistance, and treat any airway obstruction—before moving on. After ensuring breathing, assess circulation to identify and control life-threatening bleeding, maintain perfusion, and manage shock. Establishing circulation helps ensure that the oxygen being delivered can reach vital organs. Next, perform a quick disability assessment to gauge neurological function, which informs the presence of potential brain injury and helps guide priorities for imaging or further evaluation. Finally, expose the patient to inspect for hidden injuries, wounds, or signs of trauma while taking measures to prevent hypothermia. This step completes the primary survey and sets the stage for definitive treatment. This order prevents delaying airway or breathing interventions, which are immediately life-sustaining, and then systematically checks circulation, neurological status, and hidden injuries.
