There is this thing called "Assignment Despite Objection"; in fact, somewhere on the web is a copy of it--possibly @ cna.org, the CA nurses assn site. It tells management that you are not oriented to that floor and/or that type of pt., meds, etc., and that THEY
are responsible if anything gets messed up. Like, someones life!!!
I will try finding the form. Also, your union, if you have one, should be notified. You are risking your license sometimes going from ICU to floor and back. It's never a good scenario. If you can be crosstrained to another unit and float there, that is slightly better, but floating in general sucks.
