If you don't believe me why don't you read below. Of course you don't. Guess what - it was a nurse. A nurse prepares the room, bed, and supplies the doctor needs. If you are worried about nurse's hands being dirty- don't be.
Nurses have to scrub their hands with antibacterial soap for ten minutes.
Without nurses, there would be conflict in the hospital rooms. So next time you think nurses don't mean much or aren't important, just remember what you've learned.
