I might have told this story already in another thread, but here goes:
My late sister's mother-in-law had to be placed in assisted living. Because of pain, she was put on some sort of patch, maybe lidocaine. Every 3 days, the old patch came off and the new patch went on. One day, she was found unresponsive in her room and was rushed to the hospital.
At the hospital, it was found that she had twelve patches on her. Twelve. Of course, the old patch still kept putting out doses of lidocaine (?) long after a couple of days. So she had twelve patches, all pumping out varying amounts of whatever substance it was.
She was in the hospital for a couple of days and snapped back just fine. When it was time for her to be released back to the living facility, they said they couldn't accept her unless my brother-in-law paid for 24-hour nursing. Oh, yes, it was THEIR fault, but they wanted HIM to pay.
A strongly-worded letter from an attorney took care of that quite quickly and they welcomed her back with open arms, considering the alternatives. Why would he want her back there, you ask? Well, it was the best one in town and she was as happy there as she would have been anywhere outside her home. AND, now they were on alert to not make any more mistakes.
