Why not become a nurse practitioner or a physician assistant. There are different TYPES of nurses. You can get a nursing diploma, become a licensed vocational practical nurse or licensed practical nurse or find a nursing school that offers an associate degree in in nursing program, or earn a B.S. in nursing degree. Becoming a registered nurse, an R.N. means taking and passing a registration exam. It is NOT a degree or licensing program.
Becoming a a nurse practitioner requires earning both a B.S and M.S. degrees. A Physician assistant requires at leat another 3 years of school after a bachelors degree.
There are different TYPES of medical doctors as well, not just M.D.s earning an M.D. requires at least four more years of school after earning a bachelors degree, frequently more than 4 years, followed by a 6 year residency.
I do NOT speak from personal life experience, but my closest friend is an M.D. who was a neurosurgeon who is now full time faculty at a health sciences
university. She was in medical school for 7 Yeats because she was admitted to a double doctorate program, but decided not to get a Ph.D. in addition, my father was medical school faculty, but he was NOT an M.D. He taught M.D.s continuing education courses, which M.D.s HAVE to take to keep their licenses to practice medicine.
