It was just an example okay. Of course if your hands are soiled, you really have to handwash... before giving medication, you handwash.. for obvious reasons, whether your busy or not, you handwash. i was just trying to give an example where a book says something so ideal and you don't get apply it in real situations.
You handwash whenever you can.. but hasn't there been a time when you forgot to handwash because you were so busy to do it? Again, you just forgot to do it.. and NOT intentionally did not do it for an excuse of being busy.
I guess I should've just given another example.. and besides my point there wasn't about handwashing or infection control.. but the difference between the ideal and the reality..
