If a person collapses and then recovers, you should immediately call 911.

• A. Check for a pulse
• B. Wait and see
• C. Give them water
• D. Call 911

Answer: (D)

When someone collapses, it's a sign that something serious could be happening with the heart, nerves, or other vital systems, so getting professional help on the way right away is essential. Even if the person recovers, calling emergency services ensures responders can assess, monitor, and transport them if needed, and they can provide life-saving care like CPR or a defibrillator if the situation worsens. Waiting to “see what happens” or trying to give them water doesn’t address the potential emergency and can waste precious minutes. So, the best action is to call emergency services immediately to get the right help started without delay.
