What should you do immediately if you determine that someone has a life-threatening condition?

When someone is found to have a life-threatening condition, the most immediate action is to call 9-1-1 and provide general care. This step is crucial because it ensures that emergency medical services are on the way to provide advanced help. Once you have alerted professionals, you can then focus on caring for the individual while waiting for them to arrive.

Calling for help ensures that someone with the necessary training and equipment can assist, which is vital in serious situations. Providing general care, such as checking the person's condition, ensuring they are safe, and doing as much as you can to support their vital signs until professional help arrives, is essential to increase their chances of survival.

This option prioritizes the safety and health of the person in distress while ensuring that emergency services are being activated—actions that can significantly impact the outcome in these critical scenarios.
