H1N1 and floating to other departments

In my small rural hospital our OB nurses float to Med/surg when med/surg is short. If our nurses are needed we come back to the unit. Currently we made a new rule that no sick women are allowed in the unit. Before, when a pregnant woman showed up in the E.R. the immediately sent them down to us, even though the illnesses had nothing to do with being pregnant. Now, we are going to the E.R. to triage these patients and if they are sick and have to be admitted we are placing them in a room just outside of our unit. I was just wondering how other hospitals that float their OB nurses to the general med/surg floor are dealing with this N1H1 situation.

In my opinion we should not be floating to the med/surg unit at all during the flu season, especially since AWHONN sent out a notice saying that pregnant woman have four times the hospitalizations for N1H1 than the general public.
