Doctors are the medical personnel that lead the way when it comes to medical operations, while those that assist them are referred to as nurses. The doctors are actually recognized to be more superior to nurses. However, it takes more years of studies in school to be a doctor than to be a nurse. There are also actually different kinds of doctors, which include a neurosurgeon, a psychologist, and an ob-gyn.
The understanding of real medical work is with the doctors, and they take the responsibility of diagnosing patients and prescribing the treatment, which is to be undergone. This actually indicates that a doctor has more responsibilities than a nurse. Hence, the income earned by a doctor is more than that of the nurse.
A nurse just needs to graduate from a four-year academics course from a medical line, and then he or she can undergo some exams and apply for the nurse position.
