Which elements comprise the essential scene size-up in a wilderness first responder encounter?

• A. Personal Safety, Scene Hazards, Mechanism of Injury, Number of Patients, Resources Available, Environmental Conditions, and Need for Additional Help or PPE
• B. Personal Safety Only
• C. Assess Scene Hazards and Determine Mechanism of Injury
• D. The Mechanism of Injury Is the Only Factor in Size-Up

Answer: (A)

In wilderness first responder practice, the scene size-up must protect you and the patient while quickly gathering the information that shapes every decision. The essential elements are: Personal safety, to ensure you are not put at risk; scene hazards, so you identify immediate dangers in the environment or situation; mechanism of injury, which helps you anticipate likely injuries and complications; number of patients, which drives triage decisions and how many resources or rescuers you need; resources available, to know what tools, equipment, or personnel you have or must request; environmental conditions, since weather, terrain, temperature, and light affect both risk and treatment; and the need for additional help or PPE, so you have the right protection and support. Together, these factors keep the response safe and effective, guiding how you approach the patient, prioritize care, plan transport, and decide when to call for more help or equipment. The other options leave out critical elements or focus on a single factor, which can lead to unsafe decisions or incomplete care.
