How should questions be asked to an unresponsive passenger?

When dealing with an unresponsive passenger, the most effective approach is to ask yes/no questions to ascertain their level of responsiveness. This method allows for straightforward communication and helps gauge whether the passenger is capable of responding, even if it's non-verbally. Yes/no questions are clear and can often prompt a simple reaction, such as a nod or shake of the head if the passenger is able to respond in that manner.

This technique is particularly useful in emergency situations where time is crucial, and quick assessment of the passenger's condition is necessary. It can help determine if further medical assistance is required, without overwhelming the individual with complex inquiries.

In contrast, open-ended questions may not be suitable because an unresponsive person may struggle to process or articulate a comprehensive answer. Gestures might not effectively convey important information about their needs or condition, and remaining silent could delay necessary interventions. Therefore, using yes/no questions is optimal for obtaining critical information while considering the situation's urgency.
