What is the first step in assessing a patient after scene size-up?

After the scene size-up, the initial assessment is critical as it lays the foundation for patient care. This step involves quickly evaluating the patient to identify any life-threatening conditions and to establish the priority for treatment and transport. During the initial assessment, EMTs check the patient's level of consciousness, airway, breathing, and circulation, often referred to as the ABCs. This systematic approach ensures that any immediate threats to life are promptly addressed.

The initial assessment is key to determining the appropriate interventions required prior to any further detailed evaluations or treatments. It sets the stage for the following steps in patient management and ensures that the EMT has a clear understanding of the patient's condition right from the start. Other assessments such as ongoing or focused assessments come after this step, focusing on more detailed evaluations or monitoring changes in the patient's condition.
