Which of the following is NOT a step in the initial assessment of a patient?

Determining the patient's medical history is not part of the initial assessment steps in a first aid scenario. The initial assessment prioritizes immediate life-threatening conditions and involves checking the patient's responsiveness, ensuring the airway is clear, assessing breathing, and checking circulation. These steps are crucial to ensure a stable condition before more details about the patient's history are gathered.

In an emergency, the responder focuses on checking for responsiveness to understand if the patient is conscious or unconscious, which dictates further actions. Assessing airway, breathing, and circulation is critical to identify and manage any immediate threats to life. Calling for additional help, if necessary, is also part of the initial response to ensure adequate assistance and resources are on the way, allowing the responder to focus on providing care to the patient. Therefore, collecting the patient's medical history, while important for ongoing care, falls outside the immediate and urgent scope of the hands-on initial assessment.
