In hindsight (which is always 20/20
), yes it wpuld have been a good idea. Although as a staff nurse, it may have put you in an awkward position. OTOH, she may be thinking you are a snitch. But you did what you had to do, and when you are talking about narcs, it's harder to 'fix' the issue.
IMO, an incident is different than "writing her up". An incident report states only the facts; no blame is supposed to be placed. O)f course, the pertinent names will be on there (hers, and most likely yours, for doing the count). The percieved "punishment" is what stops people from filling out incident reports, when in reality, they are supposed to be used as a PI tool.
