MIL has been in same NH facility for 8 years - dementia - ST memory issues. She is mobile with W.Chair - dresses self- uses bathroom etc. herself- wandered into another Residents room (2 doors down - on the same side of the hall) - Res. is 60 yrs. old - non-dementia - had a stroke and has one leg that drags slightly. Resident slapped MIL. NH called to let us know. 2-days later I Rec'd call from NH that they are "concerned for MIL life" and want to move her (MIL) to 3rd floor. I then discovered that MIL had wandered into room again - and afterwards -other Res. came into MIL room & was found by staff wrapping tape around my MIL head and that she had told staff that she was going to "strangled her". No Staff had called myself or husband regarding this latest issue when it happened - in fact 3 days elapsed before we were informed. Other Res. has a history of anger-mngt issues. Multiple staff shared that they feel she should move not my MIL. I had just visited with NH the week before regarding moving MIL into double-room and it was agreed that it was important for her to stay in the same area and same floor that she is familiar with. I am at NH almost daily for the past 8 years and volunteer at church on Sunday - so know most of staff and residents. NH refused to tell us how they are addressing the issue with other resident - it is like they want to move and change everything about my MIL surroundings up on a floor where the majority of residents are not mobile at all. MIL quality of life will be impacted greatly if she is taken from the area that she knows and being mobile - on 1st floor - she knows the people and the area. It is like they just want the "problem" to go away and the easiest for them is to place MIL in an area where she will have limited interaction with cognitively functioning residents. I have been told multiple times and personally been aware of residents that wander and this was not an issue before other resident became violent and and threatening. Nurse on duty the day of the "taping" incident has been taking time off for the past 2 weeks when she has been scheduled to work - Other staff said that is very unusual and it happened right after incident - therefore we have not been able to get any clarification on type of tape that was used - location of tape on MIL head - if she was attempting to place around mouth and nose, etc. What are our options other than moving MIL to high-care floor and changing her entire surroundings?
