'Nurse' or 'hospital nurse' should do fine here.

No references needed. Should be in any dictionary (a.o.: Standardni recnik Srpskohrvatsko-engleski).

In the US health care system "registered nurse" is a term used to denote a professional status. "Nurse" is fine, but it does not necessarily imply the professional status. "Hospital nurse" is a bit too vague; too descriptive.

Not necessary.

Since the asker has not accepted any of the answers offered, she is not happy with any of them. Here is the story: a "nurse" is too vague. Anyone helping or "nursing" someone is a nurse, not necessariy a professional. There are two kinds of professional nurses:
1. A "registered nurse" (a/k/a :"R.N.") is a nurse with a degree.
2. A "licenced practical nurse" in the US is a professional nurse with less schooling (and a smaller paycheck), licenced by the local authority.

Since the Asker has not accepted the term "registered nurse", she is probably looking for the second option, "licenced practical nurse".

There.
