Cleaner Job than Certified Nursing Assistant?

I'm currently taking classes towards becoming a certified nursing assistant. However, I realize that I don't want to clean after someone's poop. Is there a cleaner career alternative that's still related to nursing/health field? For instance, would adding on a nurse technician certificate result in me not having to help nursing residents use the bathroom? That's really the only part that turns me off. I want to use the experience to help me get into a nursing school.
