You will also do much education with your patients; don't forget that. True, it isn't so much the classical standing -in-front-of-third-graders, but you will have moments when patients say,"Thanks! No one ever told me that before. Now it all makes sense to me and I won't eat an entire chocolate cream pie on my 1200-a-day calorie diabetic diet!"
...and those moments will make you shout with joy.
There is also nurse educators, clinical nurse educators who sorta teach new nurses what the place is all about, and nurses who just do teaching, like diabetic educators.
You will find your niche. Go for it!
