First of all, I don't think this is a case of "beggars can't be choosers". Even though you are already on the OB floor as a tech(?) being a nurse will be different, with a whole different set of responsibilities and accountability. If you like the unit and staff staying on the unit would make for an easier transition. You already know the staff and unit norms, so learning your new role would be less stressful. Transferring to another unit later would always be an option.The real question is what are your intermediate and long- term goals? Do you want to return to school to prepare for one of the advanced practice roles (NP, CRNAS, etc)? Do you plan to remain at the bedside for the foreseeable future? (and either option is perfectly fine - you have to decide what is best for you and your situation). Every hospital needs good OB nurses but any unit will give you an opportunity to make a positive impact for your patients. Even if you take a job on the postpartum unit you can always ask to cross-train to L&D, nursery, etc.Good luck to you, whatever your decision!So, I do not have any answers, you just have to decide with your head and heart what is the best choice for you.
