That sounds exactly like the first hospital I worked at. You will adjust. And you will be amazed at what you can do! As for the lack of a NICU, if we had a baby go bad and the pediatrician wasn't there, our OBs would step in and help, and our CRNAs would intubate if needed. I felt like I could handle just about anything after several years of that. I did end up at a teaching hospital as a travel nurse, and I HATED it. I missed my independence and autonomy. The hospital I'm at now has family practice residents, but most of our patients belong to the private docs so I get to be my independent self most of the time. Once you get used to it, you will probably like it. L&D tends to attract independent people. I can't speak for all small hospitals, but when I worked at one, it was not unusual to hear the doctor say, "I've been up for 2 straight days. If you really need me, call me. If you can handle it, write the order and I'll sign it in the morning." Or, if the MD found out that a med/surg nurse was being pulled to take care of postpartum patients, I've seen this order in every postpartum chart before he went to bed: "Consult with L&D nurse BEFORE calling doctor."
We really worked as a team there, the doctors respected each of us (once they got to know us) and trusted our assessments and opinions. I remember seeing one of the OBs mop the OR when we were crazy busy, had no housekeeper, and needed to do a c-section. I miss those days!
