In my past jobs it has always been just 1 or 2 RN's at a vag delivery. I now work in a large unit, and at delivery we typically have:
1) Mom's nurse
2) Baby nurse
3) Patient care tech
4) Charge nurse, if she can get away
5) Attending doc
7) med student if there is one
If we MIGHT be expecting any problems, add:
8) Peds resident
If we KNOW we are expecting problems, subtract the baby nurse and add two NICU nurses
This is one reason I REALLY like this job! Now that I am "spoiled", when I occasionally work casual at my old place of employment, where there is one or, if you're lucky, 2 RN's at a delivery, and the RN does ALL the set up, clean up, mop up, baby stuff, etc etc..........
Well, let's just say I don't miss working that way!
