One more thing--Leisa said that elderly people in nursing homes generally have 2 problems that are nursing home specific and they are UTI and electrolyte imbalance.  So IF he doesn't have a UTI, and IF his potassium level is ok (that's IF we ever get the results) then we'll go for an electrolyte imbalance and have them do a blood test for that.  We'll figure it out without any help from them evidently! Grrrrrr Love, Judy
