Which sequence correctly describes the CPR response process?

• A. Call 9-1-1; kneel next to person; place hands on the chest; position shoulders directly over the hands; start hands-only CPR; keep doing hands-only CPR until help arrives.
• B. Kneel beside the person; call 9-1-1; place hands on chest; start CPR; wait for help.
• C. Place hands on chest; call 9-1-1; kneel; start CPR; wait.
• D. Call 9-1-1; kneel next to person; place hands on chest; position shoulders directly over the hands; start hands-only CPR; keep doing until help arrives.

Answer: (A)

The essential idea is to activate emergency services first and then begin chest compressions with proper hand placement. Calling 9-1-1 right away ensures help is en route while you start life-saving work. After the call, kneel beside the person, place your hands in the center of the chest with your shoulders directly over the hands so you can press straight down from your body, and begin hands-only CPR. You continue compressions until responders arrive or an AED is ready to use. This order minimizes delays in getting professional help and ensures compressions are delivered with correct technique. Other sequences delay the EMS call or disrupt the flow of starting compressions with the right body position, which reduces effectiveness.
