I'll leave the legal part to someone who knows more than I do, but from a medical viewpoint, she isn't very credible when she claims that Terri Schiavo was "alert and oriented." That means something very specific medically. It means that someone has given you name, place, and date. Yet she then describes
Terri spoke on a regular basis while in my presence, saying such things as “mommy,” and “help me.” “Help me” was, in fact, one of her most frequent utterances. I heard her say it hundreds of times. Terri would try to say the word “pain” when she was in discomfort, but it came out more like “pay.” She didn’t say the “n” sound very well. During her menses she would indicate her discomfort by saying “pay” and moving her arms toward her lower abdominal area.Carla Iyer's description of those few simple words doesn't square with Terri Schiavo then saying "Terri Schiavo, convalescent center (I'd accept "hospital"), June 13th 1995."
I never heard that definition of the term "oriented." It's not in my Webster's dictionary software nor in the top 50 Google links for "oriented." Are you sure it was in use in Florida in 1996?
