I knew I wanted to do OB after I did my clinical rotation in nursing school. I LOVED it! I only have an ADN (working on BSN) and do FINE. If you want to be a clinical manager or specialist, I do advise the BSN route first time around, now rather than later. But if you want to be a Staff RN, and be at the BEDSIDE mostly, an AD degree will do you fine.
I agree w/fergus. We are buried under mountainous paperwork, charting for the lawyers is how I put it. You are constantly aware of the litigious world in which you practice; OB HAS A HUGE LIABLITY RATE and some nursing insurance companies will NOT insure you if you practice ANY ob nursing, even part time.
Generally, you do all for your patient, like fergus says. Vital signs, coaching, holding hands, comforting, dealing with family members (MANY OF THEM), constantly assess the status of at least TWO patients (mom and baby) at one time, and the rest. They are total care; you will also clean up the mess after delivery and make the beds; we have no aides for this. You will be required at times to do HEAVY lifting (like moving an epidural patient from bed to gurney and back for csection, who can EASILY exceed 150-200 lb)-- so make sure you have a STRONG back and get your body mechanics down NOW. Yes, this is done as a team but even if you have four people doing it, you still have a HUGE wt burden to bear safely.
You are responsible for ensuring safe recovery following delivery, vaginal or cesarian. You are also in charge of establishing breastfeeding and bonding between mom, baby and family. Your people skills must be top-notch, as well as communicative skills.
Also, you are constantly shifting priorities as you get new admissions or labor patients change status. The floor you inherit from the prior shift EASILY CAN BE RADICALLY DIFFERENT BY THE TIME YOU GET OFF YOUR SHIFT! You have to be able to be very flexible and on your toes. This is true of ANY area of nursing....and one of the hardest skills to achieve. It takes time and experience. I wish you well, friend!
