You will need either an associate's degree or bachelor's degree in nursing to become an RN, therefore you can begin working in the field much sooner than other medical professions. Depending on the type of registered nurse you'd like to become, you should consider whether an RN vs BSN degree is right for you. Most registered nurses work in a team with physicians and other health care specialists in various settings. Registered Nurses (RN) provide and coordinate patient care, educate patients and the public about various health conditions, and provide advice and emotional support to patients and their family members.
