staffing

we do 500 del/yr-does it seem safe if there are 0 babies in the nursery and no patients on the pp floor to allow 1RN to staff the labor room while the other RN is floating outside the unit on med/surg? there is a nursing assistant, but if the patient is on Pitocin and active, what would the legal ramifications be if the RN had to deal with a precipitous delivery, cord prolapse, etc. while she waits for the other RN? Have you been in this situation, is it OK? is it safe?
