A BSN degree stands for Bachelor of Science in Nursing, which is an undergraduate-level degree for registered nurses (RNs) that introduces nurses to topics such as patient care technology, research, health promotion, safety, and quality within the healthcare system. It is a four-year program for students who seek to become registered nurses or those who already are a registered nurse and have an associate's degree in nursing. Many RNs will enroll in BSN programs to further their education in the nursing field. A BSN- trained nurse will be prepared for several different career options and nursing roles after graduation, including registered nurses within a hospital, research, leadership, or management. The salary difference between RN and BSN degrees is that those who hold a BSN degree are likely to make more money and have more opportunities for career growth and satisfaction.
