I have had to deal with similar situations. I would be curious to know if the patient comes from a nursing home or receives home care. I have worked in long term care most of my life and I have discovered there are some personality types among the elderly that are very attention seeking. This was probably her way of getting more attention from her son. Often times they have nothing more to do and it can be a way for them to feel empowered. None of this is supposed to make you feel better, just understand the possible underlying cause. I am a geriatric nurse and really enjoy what I do, but I regularly encounter resident's whom I suggest 2 staff go in the room to assist when ever possible (isn't always practical.) It would be a shame if this experience caused you to leave nursing. Think of the positive responses you receive (I bet there are many more of these.)
