when I visited my mother in the nursing home where she is recovering from hip surgery after a fall at her assisted living facility, I found her sitting in her wheelchair fully dressed, and totally drenched in her urine. I grabbed a nurse for help and told her this was unacceptable. My mother has dementia from a brain aneurysm rupture 20 years ago. She tried to call for nurses several times, but nobody responded. I called for another nurse to show her my mom's predicament and it took 3 nurses 20 minutes to put my mom back in bed and change her clothes (and her wound dressing). I was shocked and saddened. How should I respond at a higher level with a complaint?
