Which of the following is an emergency medical condition?

• A. Weight gain
• B. Loss of consciousness
• C. Sore throat
• D. Rash

Answer: (B)

Losing consciousness is an emergency because it can signal a life-threatening problem that needs immediate treatment. When someone passes out, their brain may not be getting enough oxygen, and it could be caused by serious conditions such as a stroke, a heart issue, severe low blood sugar, a head injury, or a problem with breathing or the airway. Because these situations can deteriorate quickly, fast action is crucial.

If you encounter someone who is unconscious or not waking up, you should act right away: check if they respond, and call emergency services immediately. If they’re not breathing or are only gasping, begin CPR if you’re trained. If they are breathing normally, place them on their side in the recovery position to keep the airway clear and monitor them closely until help arrives. Do not give them anything to eat or drink.

The other options—weight gain, a sore throat, or a rash—do not automatically require emergency care. They’re usually non-emergency symptoms unless they’re accompanied by warning signs such as trouble breathing, swelling of the face or tongue, severe pain, or a sudden change in condition.
