Need a nursing diagnosis for care plan? Please help!?

I am in nursing school and I am making a care plan.. I have to have 3 nursing diagnosis for my patient. My patient is nonverbal, immobile, has a g-tube. I have Skin breakdown and impaired physical mobility. My 3rd one was risk for aspiration but the teacher said not to use any "Risk For" diagnosis. I was going to use Powerlessness because this patient cannot care for herself but I'm not sure of a goal for something like this because they are unable to express anything. Can someone please help??
