Step-by-step explanation:
The most correct statement when the first aider calls EMS is option 2) Call the emergency number. Give the dispatcher the necessary information. Do NOT hang up until the dispatcher hangs up. Give care to the victim.
Calling the emergency number, which is typically 911, and providing the necessary information to the dispatcher is crucial in getting help to the emergency location as quickly as possible. It is important to stay on the line with the dispatcher until they hang up, as they may need additional information or be able to provide instructions for providing care to the victim.
Waiting for EMS to arrive without providing any care can be detrimental, as immediate action may be necessary to stabilize the victim's condition before professional help arrives.
