Specialty Change

I have worked on a floor for 3 years that is rather varied-we 'specialize' in women's surgery and fetal demise, but also get medical and general surgery overflow. We are going through a lag in the patient census, so a lot of nurses are being called off or floated to other floors. My manager announced today, without any input or knowledge from any of the staff, that our unit will now specialize in women's surgery AND colorectal surgery starting in August. Umm...excuse me?? I did NOT sign up for this!!! and while I am ok with colostomies and colon surgeries on occasion, they have truly struck my weakness; poop and colostomies. I just don't think I will look forward to going to work (at all) if this will be my patient population every day that I work. I will suck it up when I have to, but I genuinely felt nauseous at the mention of this change, and the thought of my future on this floor. I have been feverishly looking at new jobs...but I'm pregnant, due in November, and I took a scholarship in April to get my BSN (not knowing this change was coming), and have to stay at least until April to 'work' it off (even though it's called a scholarship)...they already did something similar to us when a weekend nurse quit and they just didn't hire back the position, so now all the weekday nurses have to work weekends (not the end of the world, just wrong how they went about it-no warning, just changed it). I'm SOOO over this job, this hospital, and honestly hospital nursing in general. I've already met my insurance deductible, though, thanks to the pregnancy...but I'm miserable...how do I make it through the next 10 months???
