An Associate RN, or registered nurse, is one who has achieved an Associate's Degree in nursing and works in patient care and education. Associate RNs also assist in patient care evaluations and discharge planning once patients are ready to return home. The nursing profession accounts for more jobs than any other occupation in the health care industry and is expected to continue growing over the next several years.
A registered nurse (RN) is a nurse who has passed the National Council Licensure Examination for Registered Nurses (NCLEX-RN) after completing an accredited training program. These programs come in the form of an Associate of Science in Nursing (ASN) or a Bachelor of Science in Nursing (BSN).
