Which scenario requires immediate assistance in rescue operations?

The scenario involving a drowning victim who is unresponsive requires immediate assistance in rescue operations because it represents a critical and life-threatening situation. When a person is drowning and unresponsive, their airway is likely compromised, which can lead to suffocation and death within minutes if they are not rescued promptly.

Unconsciousness indicates that the victim may not be able to manage their own airway or take in breaths, which heightens the urgency for immediate action. In rescue operations, prioritizing those who are in the most critical condition—such as unresponsive individuals—is essential to preventing fatalities and ensuring that lifesaving measures can be implemented without delay.

The other scenarios, while they may necessitate appropriate medical attention, do not pose an immediate life-threatening risk that would require rescue interventions to be executed on the spot as a drowning situation does.
