Step-by-step explanation:
The correct term for a written order that allows an EMT to administer treatments such as glucose without direct communication with a physician is A. Offline medical direction. This type of directive provides protocols or standing orders that EMTs and other pre-hospital care providers can follow in specific situations without the need for real-time consultation with a medical director. Offline medical direction is contrasted with online medical direction, which involves real-time communication between the EMT and the medical director or another physician for immediate guidance and orders.
