My experience with District Nurses was with my father in law 2 years ago when , just like you, two came together at first then one on her own on a regular basis and they were truly excellent. Good luck with them , I'm sure they'll be a positive to you and your family.
2 of them arrived today it was basically to get to know me and see what needs I have. they are coming back tomorrow when the wife is here.
family war seems to be receding so that is less stress.
As I've mentioned before mate, my missus is a long standing district nurse. If there's anythng you don't understand, forgot to ask them or didn't feel you were able to ask them, don't hesitate to ask and I'll get the answers for you. ( pm me if you don't want it in the open ).
