Answer:
The abbreviation is "EMT."
Step-by-step explanation:
EMT stands for Emergency Medical Technician. They are the ones who assist patients during emergency situations. They are very skillful and are quick to react to emergent situations. When a patient calls 911, it is the EMT who responds to the situation. They immediately go the the area and provide medical assistance to the patient, including transporting the patient to the hospital facility. They are also required to have a driver's license, so that they can drive the ambulance.
In order to become a professional EMT, a person needs to have a license by undergoing an examination. The certification is provided by the National Registry of Emergency Medical Technicians or NREMT.
Thus, Aria is training to become an EMT. The description of her training program fits perfectly for EMTs.
