What is the first step in in conducting the primary survey of a patient?

The first step in conducting a primary survey of a patient is to ensure the scene is safe for both the rescuer and the patient. Once safety is confirmed, the rescuer should assess the patient's responsiveness using the AVPU scale (Alert, Voice, Pain, Unresponsive) to determine their level of consciousness. This initial assessment helps to identify any immediate life-threatening conditions that require urgent intervention.
