Why dont you all just go to your individual infection control nurse who is no doubt getting paid substantially more than you and get them to provide alist of the possible infections in the different areas and the means of tackling the infection.
As we deal with renal we are subject to the blood borne viruses so if there is going to be any splashes its on with the googles and a face mask. This I feel is all common sense so protect yourself and if in doubt talk to the staff on the ward, if they are unwilling to give the info under patient confidentiality just leave it and pass the problem up the chain. There are others out there who get paid to make the decision.
Just think of the amount of germs we as a department come in contact with every day. My rule is dont put your hands near any orifice unless you wash the paws.
be safe
