Ok. I started Basic yesterday and already have a dumb question. In my previous healthcare employment, I was always taught that treating all blood and body fluids as if they are contaminated along with handwashing, etc. is Universal Precautions. Now, I am also being introduced to Body Substance Isolation. In my assignment, one of the questions posed is: Precautions the EMT-B should take when dealing with all patients are known as: A. Universal Precautions B. General Isolation C. Body Substance Isolation D. Quarantine Isolation In my way of thinking, both Universal Precautions and Body Substance Isolation are correct answers. Would someone please explain the differences between the two?
