CPR is indicated when which condition is present?

• A. When the casualty is conscious but bleeding heavily
• B. When the casualty is not breathing and has no pulse
• C. When the casualty has a broken bone but is breathing
• D. When the casualty is only dizzy

Answer: (B)

The key idea here is recognizing when CPR is needed to support circulation and oxygen delivery. CPR is indicated when the casualty is not breathing and has no pulse, which means the heart has effectively stopped and there is no circulating blood. In that situation, chest compressions along with rescue breaths help maintain blood flow to the brain and other vital organs until advanced care arrives. If the person is conscious but bleeding heavily, the priority is stopping the bleeding and calling for help, not performing CPR. If someone is not breathing but still has a pulse, you provide rescue breaths but do not chest-compress, since the heart is still beating. If there’s a broken bone but the person is breathing, or if they’re dizzy, CPR isn’t indicated; treat the injury and monitor or address underlying causes instead.
