I'm not quite clear on what you're asking. It seems odd to ask whether a nurse is for or against a lifesaving procedure.
I'm not in favor of *unnecessary* c-sections.
I've never met a doc who did a C/S because they would make more money. I've seen a lot of not-completely-necessary C/S due to fear of litigation.
The nurse's role is to prepare the patient for the surgery - insertion of a foley, making sure she has the appropriate IV tubing and meds on board, getting her prepped in the OR (betadine scrub, slapping on the bovey pad), making sure the woman is in the correct position on the table, making sure fetal heart tones are okay after spinal anesthesia, making sure the physicians have everything they need for the surgery, generally making sure everything is running smoothly in the OR, making sure a timeout is completed, charting times, doing instrument counts with the scrub tech, etc.
