Doctors and nurses are the backbone of our health care system. Of course, many other medical professionals, such as orderlies, radiology technicians and dietitians are employed in the health care industry, but the vast majority of diagnosis and patient care is performed by doctors and nurses. Physicians obviously have more education than nurses and can prescribe medication, but depending on the health care setting, there can be significant overlap in the responsibilities of doctors and nurses.
Physicians are highly educated medical professionals who spend four years in medical school after getting an undergraduate degree and then undertake a 3- to 6-year residency working hands-on with practicing professionals in their specialty. Doctors diagnose and treat patients, including prescribing medications. Some physicians perform surgeries, others are internists or general practice doctors, and some choose to become specialists such as neurologists, cardiologists or anesthesiologists. Doctors make decisions regarding patient care and then consult with nurses and other medical professionals to make sure the care instructions are carried out.
