Nursing jobs encompass a number of positions in the health care industry. There are several levels, including registered nurses (RNs), nurse practitioners, and nurse assistants. Each position has different duties and functions. RNs are responsible for much of a patient’s primary care, including educating them on health and wellbeing, managing disease, recommending alternate treatments, and providing emotional support. Nurse practitioners have additional duties and specializations, such as midwifery and assisting in anesthesiology, which require high levels of education and training.
