Coping mechanism?

What is your coping mechanism for dealing with repetitive actions or sayings that your dementia-Alz patients do? My father has been literally saying all.day.long (frequent event) “Help me! Please help me! I’m sick!” But if you bring him food, the hospice nurse comes in, or some distraction (excluding the tv), his mind moves to something else. Things quiet down and you try to watch a show, eat a meal in peace or read a book? Here he goes again. So what is your coping mechanism?
