Sorry, but in a typical hospice setting, the urine is checked to see if a person is dehydrating and appropriate steps are taken. Don’t know which hospice you people have been using.
BTW, hospice care is a question for a Rav. Basically, instead of medical care which can lengthen a person’s life, the patient gets morphine, which slows down the heart and will shorten the patient’s life.
One must ask a Rav.
