My 71-year-old mother-in-law is a chronic alcoholic and smoker for over 50 years. Over the last several months she has lost a dramatic amount of weight, appears jaundiced, her fingers and toes are purple, and she can barely walk. Two weeks ago we got a call from her neighbor because she suddenly was no longer able to walk. When my husband went by her house, she initially didn't seem lucid and didn't recognize him for several minutes. Her house was a mess and it was obvious she was unable to care for herself very well. But she refused to go to the hospital and told him the same thing had happened the month before and she recovered in a few days. The next day my husband went back and she was shuffling around with difficulty. He convinced her to sign advanced directives and she designated him as her power of attorney. Nevertheless she doesn't want to go to a doctor and insists she can take care of herself. She is on medicaid and got a reverse mortgage on her house with $20k left in the account. I talked to a friend of mine who is an ER doc of over 20 years and she told us to take her to the ER to get a battery of tests, scans, x-rays etc. to get some answers. Once we get a diagnosis we could do hospice. What do you suggest?
