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: To become a RN nurse you can either take ADN (Associate Degree in Nursing) or you can take BSN (Bachelors of Science in Nursing) degree. Associate's degree in nursing takes two years to complete while a BSN is more comprehensive and therefore takes four years to complete.: To become a registered nurse, you need to enroll in an accredited nursing school. The criterion for enrollment in a nursing school is a high school diploma or GED, good grades in science subjects like chemistry and biology and a high percentage in SAT or ACT exam.
