Which of the following items is included in the emergency medical kit (EMK) on the CRJ700?

The inclusion of first aid supplies as part of the emergency medical kit (EMK) on the CRJ700 is crucial for responding to medical emergencies that may arise during a flight. The EMK is specifically designed to provide essential resources for the treatment of passengers or crew members who may experience a medical issue while in the air.

First aid supplies typically consist of items such as bandages, antiseptics, gauze, and gloves, which allow trained personnel to administer basic medical care until professional help can be obtained upon landing. This preparedness can make a significant difference in the outcome of medical situations that might otherwise escalate without the necessary supplies.

In contrast, other items like megaphones and life vests serve different purposes and are categorized under other emergency equipment. For instance, a megaphone is used primarily for communication and crowd control. Adult and infant life vests are essential for overwater safety and are not part of the EMK since they relate to water emergencies rather than medical emergencies. Thus, the focus on first aid supplies in the EMK highlights the importance of immediate medical response capabilities during flights.
