I went through this same thing a couple years ago with my witness parents, both in their 80's. They had appointed an elder (who is also a cousin by marriage) as their durable healthcare representative. I was SO upset that it took a few days to even reapproach the subject. I am a nurse, very active in my parents' healthcare, and the idea of giving up control of their health care decisions to that equally elderly man was unbelievable.
My parents, too, explained that they were trying to avoid putting me in the potentially painful spot of making a blood related decision for them. (Obviously the reply taught from the podium.) They did NOT know the difference between 'power of attorney' and 'durable healthcare representative' or what an advance directive meant. They did NOT realize they were giving him complete power to decide ANY healthcare related decision in the event they could not speak for themselves. The example I gave them was, "What if you have a stroke, and may very well need a feeding tube until it is determined that you can swallow safely again? Have you talked about your wishes? Do you trust him to know what you want? Do you realize he would name your nursing home, your doctor; even control whether you can have visitors?!?!?!? This is so much more than just an issue of blood!"
Then I asked, "Did you not trust me to honor your wishes? That out of respect for your decisions, I would ever dream of going against you?" Now, you would think I would have had sense enough to stop there. After all, I was already upset. But I had to ask it! "What if it were the other way around? If I were sick, would you honor MY wishes?" Of course, my Mom said, "I could NEVER let you have blood!"
Well, we later had a long sit down about "advanced directives": my parents' wishes about feeding tubes, ventilators, pain control, and blood fractions (no one was more confused than I was, but I tried to keep it all straight). They retrieved the copies of the advance directives with the elder's name on it, and they filled out new ones. And it was a good thing, too, since Mom promptly had a stroke, and then a bleeding ulcer! And Dad with multiple myeloma.
Not to drone on, but here's a little background: raised a 3rd generation witness, Dad an elder, never baptized, college scholarship, married young, long search for something missing, found it in a little local church. Now grey headed.
I love the boards! It used to be such a lonely thing--how wonderful to know I didn't imagine all that childhood stress!!!
