Hospice question from a new-ish LTC nurse

Hi. I am LPN who graduated last June and have been iin my LTC facility for exactly one year now. I have a 20 bed wing and have had about 12 residents paa away on my wing since starting. We don't have a designated hospice wing but I have had up to 6 hospice patients on my wing at any given time.

Now, my question... I currently have a lady on hospice who has been declining significantly for about three weeks now. This lady has always been very independent and has been known to refuse certain medications and treatments for the entire time that I have known her. She was just placed on hospice about 2 weeks ago. She has some dementia but is fairly oriented, has no POA, and signed her own hospice consents. This is a lday who has certainly always made her own decisions and has expressed to myself and other nurses that she intends to continue to do so. On hospice, she was prescribed prn ativan, prn morphine concentrate, fentanyl patch, and haldol gel. She has repeatedly refused the morhpine, although not all the time. Occasionally she will acknowledge that her pain has gotten worse and will accept the morphine. She has, however, told the nursing staff that she does not like how the morphine makes her feel and would rather not have it.
My thought is that she has every right to decide when she takes it and when she doesn't. We were always taught that the right to refuse was part of any med administration. My NM, on the other hand, seems to believe that she should be taking it anyway. She has placed in the resident's drink without her knowledge and has encouraged the nursing staff to drip it into her mouth SL while the resident is sleeping. The DON seems to go along with the NM on this. I work with this lady every day amd have for a year. She has very little family that comes to see her and I feel that it is unethical to purposefully not follow her obvious wishes. I believe that if we do this then we lose credibility and trust that we floor nurses have built up over the past year and that, since she has almost no family, that we should advocate for her wishes to be respected as a family member might were they here. At the same time, I am worried about continuing to push the issue as both the NM and DON have made it clear where they stand. I feel very torn between standing up for what I believe to be right and backing off to protect my job. Does anyone have any ideas on how to best handle this situation or similar situations that may come up in the future? Any thoughts at all are appreciated.
