Students who already possess an LPN credential can apply to LPN-to-BSN programs to advance their careers and get an RN licensure. Registered Nurses (RNs) are responsible for a multitude of medical functions in a healthcare facility and are generally regarded as a foundational pillar in nursing. A BSN degree is preferred by most employers in the field of nursing, therefore, opting for an LPN-to-BSN program might be beneficial for those who have an LPN degree. An LPN-to-BSN would require two to three years to complete with full-time study. Students attending a part time program might have to invest more time, though they can continue to work while they study.
