A BSN, or Bachelor of Science in Nursing, is an undergraduate degree that prepares students for a career in nursing. This program typically takes four years to complete and includes both classroom instruction and clinical practice. Students learn about patient care, health assessment, pharmacology, and nursing ethics, among other subjects. Earning a BSN can enhance job prospects and is often required for advanced nursing roles. Many healthcare facilities prefer or require nurses to have a BSN due to the increasing complexity of patient care. Graduates can pursue licensure as a registered nurse (RN) and may further their education with a master's degree in nursing or related fields.
