determine what the person was doing.

Explanation:

In a potentially serious or life - threatening first - aid situation, the most crucial step is to call emergency services immediately. While treating minor injuries (like scrapes, cuts, and bruises), finding nearby help, or determining what the person was doing may be relevant in some cases, they do not take precedence over getting professional medical assistance as quickly as possible. Calling 9 - 1 - 1 (or the local emergency number) ensures that trained medical personnel are on the way to handle the potentially life - threatening situation.

Answer:

Call 9 - 1 - 1 immediately.
