Final answer:
After activating EMS, an officer trained in CPR should a) begin CPR immediately for an unresponsive victim to maintain vital blood flow until EMS arrives.
Explanation:
After activating EMS, an officer should a) begin CPR immediately for an unresponsive victim if they are trained and it is deemed necessary. Prompt action can be crucial in a life-threatening situation, especially when waiting for EMS to arrive, which might take some time. Performing CPR can help maintain vital blood flow to the brain and heart, potentially saving the victim's life. It is important to remember that for drowning victims, the first priority is to remove them from the water to stable ground before starting CPR, as CPR is ineffective in the water. However, in general emergencies where CPR is applicable, starting CPR sooner rather than later is recommended.
