What is the first step in the adult BLS sequence when one or more rescuers are present?

• A. Start chest compressions immediately
• B. Verify the scene is safe
• C. Check for breathing
• D. Call emergency services

Answer: (B)

The first thing to do is make sure the scene is safe. Ensuring your own safety and that of bystanders before approaching the patient lets you work without interruptions and prevents adding harm. When more than one rescuer is present, one person can quickly assess hazards and confirm safety while another calls emergency services and retrieves an AED. Once safety is confirmed, you can move on to assess responsiveness and breathing, then start CPR and use the AED as indicated. Actions like starting chest compressions or checking breathing should follow safety confirmation, and calling for help is urgent but can be done alongside beginning CPR if another rescuer is available.
