Here they all need patent IVs. And they all have to be #18g.
MW patients refuse somewhat regularly.
As far as bad outcomes due to a refusal? Well, I work antepartum, so except for my cervidils, they're all high risk. We had one woman, MARGINAL previa. Marginal...borderline not even a previa....Anyway, she'd been with us for about a month and just refused to keep getting stuck every couple of days (saline locks weren't keeping on her, no matter how often we flushed, and the docs wouldn't do a kvo). So she refused.
Thankfully, she bled one night. Just about the size of a deck of cards on her underwear. We saline locked her, and she was fine. The next night (which was Aug 1st btw) she hemorrhaged on our unit. 12th floor. 4 floors away from L&D/the OR.

But she had the iv from the night before. She was a pretty easy stick, so we could have easily popped one into her that night, but thank god, it was one less thing to worry about, and one less thing for L&D to run their mouths about.
