What should flight attendants do if a passenger exhibits signs of distress?

When a passenger exhibits signs of distress, the appropriate action for flight attendants is to immediately report to the captain and prepare for potential emergencies. This response is critical because the safety and well-being of all passengers is the top priority during a flight. By informing the captain, flight attendants ensure that the situation is escalated appropriately; the captain can assess the situation and decide on necessary actions, which may include diverting the flight, communicating with medical personnel, or implementing emergency protocols.

Preparedness is essential in handling distress situations, as they can escalate quickly if not addressed properly. Immediate reporting allows the crew to act effectively and ensures that any necessary medical assistance can be arranged swiftly. Additionally, it shows that the crew is attentive and responsive to passengers' needs, which is an important part of providing excellent customer service and maintaining safety onboard.

The other choices do not align with the protocols and level of responsibility expected of flight attendants in such situations, potentially compromising the passengers' safety and well-being.
