What action should the Communicator take after informing the Captain of a medical emergency?

The action of collecting the Quick Reference Guide (QRG) is crucial in a medical emergency. The QRG provides immediate access to standardized procedures and guidelines that are necessary for assessing and managing various medical situations effectively. It ensures that the Communicator, as part of the crew, follows the appropriate protocols during the incident, which can increase the effectiveness of the response and help to safeguard the wellbeing of the casualty as well as other passengers. By having the QRG on hand, the Communicator can refer to specific actions that need to be taken, the necessary equipment available, and any emergency contacts that may need to be alerted.

Other options may involve important aspects of handling emergencies, but gathering the QRG is fundamental to ensuring that the response is coordinated and precise, directly contributing to the care provided to the affected individual.
