They're not going ask if someone is actively dying obviously, but if they're in a position where they can ask those questions and the patient is able to answer then they could be seen as liable for a miscarriage if they don't ask and they give something harmful.
It's about protecting themselves. For example, I was a man working in childcare and I always had to be careful with my interactions with children and to minimise the times I was ever alone with a child as much as possible, because people can and will assume the worst about men in a position of power over children. So I can understand people doing everything in their power to protect themselves, even if they have to ask questions other people may be annoyed by.
