Correct answer: B — Check responsiveness → Activate EMS (call 911) → Check breathing and pulse → Begin CPR if no pulse → Apply AED when available
The correct BLS sequence for an unresponsive patient in the dental office is: (1) Check responsiveness (tap and shout); (2) If unresponsive, call EMS (911) or direct someone to call; (3) Check breathing and pulse simultaneously (no more than 10 seconds); (4) If no normal breathing and no pulse, begin CPR (CAB: 30 compressions, 2 ventilations); (5) Apply AED as soon as available and follow prompts. In a dental office with multiple staff, these steps can be performed simultaneously (one person calls while another begins CPR).
