I am concerned about my 92 yo mom. Over the last few days she s become extremely confused and said she felt very tired. She had pneumatic, congestive heart failure, atrial fibrillation and acute kidney failure in November 2017. She went to rehab to regain her strength and went home in mid December. She has continued to get stronger. Mid week she told me she was very fatigued. As the week progressed she became more confused. She is unable to remember names, is unable to tell time, has missed meals at her independent senior citizen apartments, left her purse after attending a meeting, etc. She told one of the managers that she was going to church to hear Billy speak one last time before she dies yesterday. The manager speculated that she may have a UTI. She is prone to them. She does not dink enough fluid. Ideas?
