I called a doc I that goes to the same 12 step program I do, and asked him how he would handle it. He said he'd have to look at the big picture. Are the papers in line with the states requirements? What mental state were they in when they were signed? Are they able to make their wishes known? Is this a medical condition that doesn't have to be life threatening?
If family is who signed them in and answered questions-don't volunteer that they are JWs. Restrict visitors--notify security if you think they are going to gang up. When someone is registered in the hospital, you have the option of not allowing their name to be made public. If somene asks what room they are in, they won't even show up on the computer as a patient. He said personally, he'd loose the blood cards(oops) and try to have new papers signed. Also, if you should be made Durable Power of Attorney, in Texas it supercedes the Power of Attorney for Healthcare. Now,keep in mind this is some stuff from the doc, and some is what I've learned working as a nurse.
The last thing the Doc said was that it's really up to the doctor to decide what's in the best interest of the patient. And since elders are not his favorite people, either forget to call them!!! I have had security escort them from the property and ban them from returning. (One of the best times of my life!)
When in doubt, before something should happen, check with hospital administration. If a problem should ever come up, they'd be ready for it!!
Hope this helps a little. Don't take my word as gospel--double check before an emergency happens. Also, restraining orders against cults (JWs) that don't act in the best interest of the patient are WONDERFUL!!!!
