. You can play on your documentation skill, attention to detail and ability to learn, and being a great team player. Also if you did any user training is a great skill used in nursing. On the negative side IT may be considered a face in the screen experience (as in a programmer) where creativity and problem solving is a meaningful skill. Not great for nursing.
Informatics is great, although your success is probably depends upon gaining some thorough hands on clinical experience. There maybe alot of years in the trenches before you get the opportunity to again sit in a cube.
The great thing about nursing though is there are so many types of experiences available to you. Look around to see what is really respected regardless the type of nursing you work in i.e. advanced degrees, certifications, professional affiliations etc. Sorta like getting a Microsoft Certification in advance network engineering.
Good luck and have fun!
