How can visiting nurses be treated so poorly?

Court House - How can visiting nurses be treated so poorly? My daughter has been in peoples houses day in and day out with family members around and now she thinks she may have COVID. Went to urgent care-they're backed up for a week with waiting room full of tourists in bathing suits, went to ER -- they don't do testing! Shouldn't a nurse have some priorities?? She has patients waiting to see her and is afraid to go if she has it!! If a nurse comes in for testing (with a fever by the way) can't you slip her in ?
