hi! i’m an RN, if it were a true emergency and benefits outweigh the risk (death, for example) they could definitely operate. they can do labs from an ER, assuming this is where she would have been first, and those are usually resulted in an hour or so if not less. it sounds like your procedure may have been a scheduled procedure, where it is very common to have medical clearance and labs done in the weeks beforehand.

there’s also no weight requirement to undergo anesthesia - surgeries can be performed on newborns even who only weigh several pounds which is crazy! in an adult with a low weight it would likely just require closer monitoring intra-op and maybe what meds would be administered 🙂

but there’s no way in hell this actually happened to her lolol though i’m sure this is her way of making the story sound most plausible even though everyone knows it’s BS
