i knew you couldn't answer my questions. If you were a PA or NP, you would know the answers. And trust me, you are wrong on your assertion there is no such thing as contact 1 and 2. Here is a hint; CDiff is contact 2. One difference is alcohol foam cannot be used to clean hands as it does not kills the spores. Whereas alcohol foam can be used in contact 1 isolation. If you were in this field you would know. Now either answer my questions or not. I know you can't. You've spent all day googling lol. Btw, tb patients are placed in airborne and droplet.Typical hypocrite can't even answer the original question. What is the difference between contact 1 and contact 2 precautions provide a link that distinguishes the difference? Tb falls under airborne precautions and not droplet proved you wrong there. Just trying to change the subject and while your at it tell me the different classes of alkylating agents? what are the main differences between antimetabolites, anthracyclines,Topoisomerase Inhibitors? How many components in TKA? name the components? How many components in THA? and name the approaches? You may be saying to yourself what does cancer treatments and orthopedic procedures have to do with precautions? well absolutely nothing but since you failed to answer the original question im just applying your logic. If you actually worked in the medical field which i doubt you do you would know the industry is large with many different specialties.
