This is inspired by another thread. How do you sign your name when you sign off on stuff at work? I use my first initial and full last name. Like this: O. Bobcat, RN I have a pretty unique last name, and there are no other nurses in my state with my first initial and last name.
My boss at my previous place of employment told me I needed to use my full name when I signed, but I never changed the way I sign after she told me that (I'm such a rebel!)
I use my full name including middle initial when I sign non-nursing related things.
