Depends on what kind of person the nurse was talking to.
To give a personal example. My mother was christian. When she was on her deathbed, I sent a priest to her to give her the last rites. Not because I'm a believer, but because I thought, that's what my mother would have wanted and maybe it gave her some comfort.
So if this elderly person was a christian, I see nothing wrong with the nurse talking to her like that. She should have left out the gay part, that's for sure. But otherwise it's entirely dependent on the situation and the people involved.
