okay i am new to this site so if i am posting in the wrong area, i apologize. I need advice i am scare of being a nurse, not because of blood, crap, puke or anything along those lines, but i have a fear of catching diseases..along with other things. How does a nurse avoid getting lice, scabies, and bed bugs when you are right there with the infected patient? I know this sounds immature and silly, but i am sure i am/was not the only one who has had this fear...so please ..advice??
