Is there such thing as an occupational therapy nurse?

Can a nurse work in occupational therapy? If so, what would her role be and how would she assist the occupational therapists? I am in nursing school and my best friend is going to school to be an OT assistant. I find what she is doing interesting. I wouldn't want to change what I am doing...I definitely want to be a nurse. But, one of the nice things about nursing is that the field is so diverse.
