Who can authorize the use of the expanded medical kit (EMK)?

The expanded medical kit (EMK) is a resource equipped on certain flights to assist in managing medical emergencies. The authorization for its use is specifically granted to qualified medical personnel or dispatchers, which is why the answer indicating dispatch or physician is correct. This is based on protocols that ensure such kits are utilized appropriately and safely, as the usage of the EMK often requires medical knowledge to assess the situation and make decisions on treatment options.

While the other options may suggest that various personnel could potentially engage in situations requiring medical support, only qualified medical personnel have the training to interpret the situation and make decisions concerning the proper use of medications and tools within the kit. Hence, ensuring that the EMK is used safely and effectively during flight is a critical factor in why authorization is limited to dispatch or a physician.
