Which call type corresponds to Unknown Problem (Person Down)?

• A. Traffic Collison/ transportation incident
• B. Unknown Problem (Person Down)
• C. Transfer/ Interfacility/ Palliative Care
• D. Airway/ Arrest/ Choking (Unconscious)- Infant< 1 year

Answer: (B)

Unknown Problem (Person Down) is the call type used when a caller reports a person who is down with no clear or stated cause. The key idea is to classify it as a general medical emergency rather than a specific condition, so the dispatcher can start with broad, life-safety questions (like responsiveness and breathing) and guide the responder to urgent medical needs.

This category directly matches the situation described, whereas the other options refer to clearly defined scenarios: a traffic collision or transportation incident is for vehicle crashes; transfer/interfacility/palliative care covers moving patients between facilities or end-of-life care; airway/arrest/choking for an unconscious infant under 1 year is a specialized pediatric airway/arrest scenario. Using the Unknown Problem (Person Down) label ensures the call is routed as a medical-down scenario and prompts appropriate initial actions, such as checking responsiveness and breathing and requesting EMS assistance promptly.
