Before attempting to help an injured person, what is the most important initial step?

• A. Phoning a responsible adult.
• B. Initiating CPR.
• C. Examining signs of shock.
• D. Checking the scene for safety.

Answer: (D)

The most important step is to assess the scene for safety before you do anything else. If the area around you is dangerous—traffic, fire, fumes, unstable debris, or another hazard—you could become another victim while trying to help. In such cases, protect yourself first by moving to safety if you can do so without worsening the situation, or wait for professionals and have bystanders call for help. Only after the scene is deemed safe should you proceed to assess the person (responsiveness, breathing) and provide appropriate care.

The other actions depend on a safe environment being present. Phoning someone else can be important, but it doesn’t protect you or the patient if the scene is unsafe. Starting CPR is only appropriate if the person is unresponsive and not breathing normally. Checking for signs of shock is something you do once safety has been established and you’re assessing the patient’s condition.
