Final answer:
The correct statement about EMTs is that in some states, they are trained in advanced airway management and IV therapy. Manual defibrillation is not a required skill for all EMTs, there are more EMTs than paramedics, and EMTs typically operate under medical direction.
Step-by-step explanation:
The correct statement regarding the Emergency Medical Technician (EMT) is: 1) In some states, EMTs are trained in advanced airway management and IV therapy. While EMTs provide basic care and can administer certain medications like oxygen for respiratory problems and epinephrine for allergic reactions, the scope of practice can vary by state, including advanced procedures. It is not accurate that all EMTs are required to learn and perform manual defibrillation, as Automated External Defibrillators (AEDs) are more commonly used by EMTs and are designed for laypeople. Additionally, there are more EMTs than paramedics in the United States, as becoming a paramedic requires additional 2-4 years of training beyond EMT certification. EMTs usually work under medical direction and are not generally licensed to provide basic life support without guidance.
