Considering how none of the DO/MD/surgeons I know put any of their shit in their signature, I wouldn't ever put any of that bullshit at the end of mine. Email's, sure, outside on the sign for your practice, definitely, on a paper when you sign something or on your personal shit - fuck no.
Pretty sure if I ever saw any RN sign with RN at the end I'd have to laugh at them, and show it to other people to continue the laugh.
Typically people in those positions have headers and printed signatures with their license/title/degree/whatever listed at the end, and sign above it with their name with nothing following.
