Which action is included in the basics of scene size-up?

• A. Complete a 360-degree assessment
• B. Complete a financial audit of the response
• C. Immediately begin rescue without assessment
• D. Do only a visual sweep from outside

Answer: (A)

Surveying the scene from all directions is essential because it builds safety and awareness before you touch a patient. A 360-degree assessment serves as a foundational step in scene size-up, letting you spot hazards (like unstable structures or hazardous materials), understand the mechanism of injury, locate the patient and determine the best access and egress routes, and decide what resources you’ll need. By circling the scene, you plan your approach, ensure you can adapt if conditions change, and reduce risk to yourself and others. The other options fail to provide this comprehensive safety check: a financial audit has no relevance to scene safety or patient care, rushing into a rescue without any assessment endangers everyone, and a limited external sweep may miss dangers or patient location on other sides of the scene. That makes the 360-degree assessment the necessary element in the basics of scene size-up.
