Final answer:
An EMT working under the Medical Director's guidance provides pre-hospital care following established medical protocols. Paramedics, having undergone 2-4 years of training including chemistry and anatomy courses, can administer a wider range of emergency medical procedures and drugs than EMTs.
Step-by-step explanation:
When an EMT is operating as the Med Director's extension, they are effectively carrying out the medical directives and protocols established by a medical doctor, who holds the position of Medical Director. This is common in the field of emergency medical services (EMS), where paramedics and EMTs function under the oversight of a supervising physician to provide pre-hospital care. Their work environment can vary; some EMTs and paramedics are employed by fire departments, hospital-sponsored ambulance services, government departments for emergency healthcare, or private companies contracting with government bodies.
The scope of practice for EMTs includes basic care, while paramedics have more extensive knowledge and are trained to administer a broader range of emergency drugs and procedures. Training to become a paramedic typically takes 2-4 years, including experience as an EMT. Given the complex and often urgent nature of their work, courses in anatomy, physiology, medical terminology, and chemistry are important for those pursuing a career in this field.
