Final answer:
Calling 911 during an emergency is essential to get professional help quickly due to the potential for extreme physical danger. Emergency services funded by government taxes respond without additional charges. Timely action, such as providing CPR only after removing a drowning person from water, is critical.
Step-by-step explanation:
Phoning 911 immediately in the case of an emergency is crucial as it ensures that professional help is on the way as swiftly as possible. Emergency situations often present the potential for extreme physical danger, and a rapid response can be the difference between life and death. Additionally, the importance of a rapid assessment of neurological function in an emergency cannot be overstated, as it can point to life-threatening issues that require immediate attention.
Bystanders might experience uncertainty or hesitation due to phenomena such as the bystander effect, where the presence of others leads to a diffusion of responsibility. However, taking initiative to call 911 can activate the emergency response system, which is made up of emergency medical services, fire departments, and police departments. These services are funded by taxes and provided without additional charge to anyone in need, and their personnel are trained to handle a wide range of emergencies with speed and effectiveness.
Lastly, in the context of an emergency like a drowning incident, removing the person from the immediate hazard (the water) before starting CPR is an example of critical thinking and appropriate action in emergencies. Cell phones are important in these situations because they enable us to communicate quickly with emergency services and locate people in crowded areas.
