What should a flight attendant do if a passenger collapses?

In the event a passenger collapses, the first step for a flight attendant is to check for responsiveness and call for assistance. This is crucial because the flight attendant needs to quickly assess the situation to determine whether the passenger is unconscious and unresponsive, and if they require immediate medical attention. Calling for assistance ensures that appropriate medical personnel can be alerted and prepared to intervene, potentially mitigating any serious health issues.

Checking for responsiveness involves gently shaking the passenger and speaking to them to see if they respond. If the passenger does not respond, it's critical to alert other crew members and possibly initiate emergency protocols, which could include performing CPR if necessary, depending on the training and situation. It is important to act swiftly but carefully, as there are specific protocols to follow in emergency medical situations to ensure the safety and well-being of the passenger and other individuals on board.

The other options do not provide the same level of immediate response required in a medical emergency, which could lead to delays in necessary care. Performing CPR immediately may be warranted in some situations, but without assessing the passenger first, this action could be premature. Waiting for the medics to arrive or continuing with service ignores the urgency of the situation and compromises the passenger's safety.
