To clarify, are you thinking about becoming a hospital unit-based educator? Or something more along the lines of a clinical instructor for a nursing program?
A clinical instructor job can be a good way to try out teaching because it's usually once a week. Most people do it as a side job, and a lot of programs let you skip a semester if you have other things going on in life. To me, it's fulfilling to hear from past students who have become nurses. A lot of schools require a master's degree though. 
Unit-based educators (the educators that track unit competencies and plan the orientation schedules for new hires) are often salaried based on 40 hours per week. If you work on a unit where the educators are very involved in QI or you have a lot of nurses on orientation, it can be hard to get everything done in 40 hours. It's also worth thinking about the fact that you would likely be going from three days a week to five days a week.
Good luck to you! I hope you're able to find a good fit.

A lot of nursing instructors have a surprisingly poor understanding of how the NCLEX works. This is a good example of it.
On the NCLEX, both passers and failers tend to score around 50%. What determines pass/fail is the difficulty level of those questions where you're hitting that 50% mark. Do they have to give you really hard ones or really easy ones? That's the determining factor.
Jcarro, 'select all that apply' questions are generally considered to be harder, which is good news for you. Good luck on your results. Let us know how it turns out.
