What is the first phase of patient assessment?

The appropriate first phase of patient assessment is the scene size-up. This essential process involves evaluating the scene for safety, determining the mechanism of injury or nature of the illness, and identifying the number of patients involved. The scene size-up helps ensure that the EMTs approach the situation safely and that they have enough resources for the potential needs of the patients.

By conducting a scene size-up first, EMTs can assess for hazards that may affect both the responders and the patients. Additionally, this phase allows EMTs to gather critical information that will inform their subsequent actions, including whether they need to call for additional resources or take specific protective measures. Understanding the dynamics of the scene sets the stage for a more effective and responsive patient assessment and care plan.
