Medical Field Essential Information

Educational qualifications for jobs in various fields of medicine vary. Some occupations only require on-the-job training or the completion of a two-year program. For other medical careers, you'll need a four-year or doctoral degree. A license is needed for most medical jobs, and each state may have different licensing and certification requirements.

There are a number of different options for those who wish to seek a career in the field of medicine. Explore a few options that are available in the table below.

Medical Careers

The medical field has a range of career opportunities, such as physicians, nurses, and radiographers. If you can cope well in stressful situations and have compassion, patience, and physical stamina, a career in medicine is a good fit for you. You must also demonstrate excellent communication, math, and technical skills.

Physician or Medical Doctor

Physicians use their medical expertise to monitor the health of their patients and diagnose illnesses. They train for at least ten years, including obtaining a bachelor's degree, attending medical school, and then working as a resident physician.

Future physicians must first earn a bachelor's degree, studying courses in organic and inorganic chemistry, biology, physics, mathematics, and English. Additionally, they generally take courses in the humanities and social sciences and may opt to volunteer at a hospital or clinic.

After earning a bachelor's degree, prospective physicians must attend medical school. In the first two years of med school, students spend their time in the classroom studying a wide array of subjects. The last two years are spent working in clinics under the direct supervision of practicing doctors, learning to diagnose patients in a variety of medical areas. After completion of medical school, they hold either a degree as a Doctor of Medicine (M.D.) or a Doctor of Osteopathic Medicine (D.O.), depending on which path they chose.

After finishing medical school, physicians may opt to intern for a year before beginning a required residency at a hospital. Resident physicians specialize in a particular medical field, receiving paid on-the-job training. Residencies may last anywhere from two to six years, depending on the nature of the training area.

In order to practice, physicians must obtain a license from the licensing board in the state in which they wish to work. Physicians can also seek certification in their specialty through board examinations approved by the American Board of Medical Specialties (ABMS). Both a license and certification require continuing medical education in order to maintain these credentials.

The U.S. Bureau of Labor Statistics (BLS) lists all types of physicians separately. For the purpose of this article, the information given is based on family and general practitioners. As reported by the BLS, the job outlook for family and general practitioners will increase by 10% from 2018 to 2028 with a median annual salary of $201,100 in May 2018.

Registered Nurse

A registered nurse (RN) cares for patients in hospitals, clinics, nursing care facilities, and other health care settings. Becoming a nurse requires at least the completion of a diploma program from an approved nursing program.

Those seeking to become registered nurses attend nursing school and can choose from three educational options: a bachelor's degree in nursing (BSN), an associate's degree in nursing (ASN), or a diploma program. While all three programs allow graduates to be employed as a nurse, salaries, and job advancement opportunities vary with each. The curriculum for nursing students includes courses in health and nutrition, microbiology, anatomy, physiology, and medical terminology.

Nursing programs include clinical experiences for students, performed under the supervision of a registered nurse. Generally, working as a certified nurse's aide (CNA) or licensed practical nurse (LPN) is not required for entry into an RN program; however, some students might find the experience beneficial.

After obtaining a degree or diploma, nurses must pass the National Council Licensure Examination (NCLEX), which is required in every state. Some states may have additional prerequisites for employment.

According to the BLS, there will be a 12% increase in jobs for registered nurses between 2018 to 2028, and their median annual salary as of May 2018 was $71,730.


Physicians require radiographers to take and produce X-ray films called radiographs. When a doctor needs to examine a patient through radiologic means, a radiographer is called upon to explain the procedure to the patient and walk them through it. They are also responsible for ensuring that all machines and devices are working properly before starting a procedure.

Several educational routes are available to radiographers. Some choose to enter into certificate programs that last 21-24 months. Others enter into an associate's degree or bachelor's degree program in radiologic technology. Schools offering these programs need to be accredited by the Joint Review Committee on Education in Radiologic Technology. Classes in these programs cover subjects like pathology, radiation protection, medical terminology, medical ethics, radiobiology, physiology, and radiation physics.

A radiographer may acquire the necessary work training through an entry-level position or an internship. The American Registry of Radiologic Technologists also offers job training in specific radiographic specializations. New radiographers work under an experienced radiologic technologist, familiarizing themselves with the hospital and the equipment involved.

Radiographers have to be licensed with the state due to the hazards of working with radiation and radiologic equipment. Federal legislation requires that radiographers be properly trained to handle this equipment safely. The exact requirements vary in each state, so contacting a state's health board is ideal for license information.

The BLS categorizes radiographers as radiologic technologists. The job growth for radiologic technologists will increase by 9% for the years 2018 to 2028, and their pay as of May 2018 was $59,520, according to the BLS.

To summarize, those who want to become a physician need to obtain a bachelor's degree, a medical school degree, and licensure to work in their desired state. Registered nurses have a number of degree and diploma options but ultimately need to obtain state certification in order to work. Finally, radiographers may complete a certificate program or a traditional degree program and also need to obtain state licensure.
