Nursing continuing education is required after acquiring an initial nursing license. Nursing is considered a lifelong learning process. Continuing education courses for nurses, can also affect the quality of care and patient outcomes by providing necessary opportunities to improve practice skills and knowledge through educational courses. Most states require nurses to complete some form of continuing education.
CE is just the abbreviation for continuing education, so it's really more of a generic term to explain continuing education. On the other hand, CEU (a continuing education unit) refers to a unit of credit equal to 10 hours of participation in an educational course or approved activity usually used by a university. The key here is choosing an approved provider who offers an accredited course.
