Continuing Education

What are some website that offer FREE CEU's that are credible? Or, for a small fee for unlimited topics. Not only to earn my needed CEU's, but sometimes I just want a refresher on some topics.
Medscape.com has free CEU's.

If you aren't so married to the idea that it has to be a website to be 1) free or inexpensive or 2) good refreshers, join your state nursing association and you'll be able to access bazillions of online and in-person CE for short money and large satisfaction. Also, remember that many certifications and licensures don't accept online CE if it's less than 30 minutes, so whipping off a pile of those 15 minute ones in an afternoon will teach you something (no learning is ever wasted) but not impress your BoN or cert board.

If you belong to a specialty organization, you can get continuing education at a reduced rate. For e.g., I belong to the Oncology Nurses Association, and have done many of their CE. Those hours count toward my certification renewal.I have done some CE programs provided by Nursing Spectrum, medpage, NOEP and some others.
