I can't speak to AWHONN guidelines, but no hospital in which I've ever worked staffed with a single RN for mom and baby, even for a vaginal delivery. I can't imagine that it meets professional guidelines for a C-section.
My most recent OB experience is getting admittedly distant, but we were required to have a surgeon, first assistant, scrub nurse (or scrub tech), circulator, anesthesia provider and infant care provider. A surgeon, anesthesia, and 2 nurses is not an acceptable team.
If administration is not willing to have additional nurses available in house, then one of them needs to don scrubs
,participate in the next emergency C-section and sign the surgical report.
