Final answer:
When seeing someone possibly in need of help, first observe your surroundings, then approach if safe to do so and assist or notify an authority figure.
Step-by-step explanation:
First Response to Emergency Situations
When you witness an emergency, such as a person lying on the ground possibly needing help, the first thing you should do is observe your surroundings. It's important to assess the situation for safety and determine if the bystander effect is at play. If safe to do so, approach the person to check if they are okay and require assistance. If you are unable to provide help directly or unsure how to, it is crucial to notify an authority figure such as an adult, a healthcare professional or dial emergency services immediately.
Remember, your actions—even if it's just calling for help—can make a significant difference in emergency situations.
