The major characteristics of chemical control agents as a group include: (Select all that apply) O They may be placed into 3 groups based on strength of control: sterilants, disinfectants and antiseptics O Their primary function is to kill, inactivate or inhibit growth of microbes O They have different toxicities that govern their safe use. O Some of these are so toxic that they must be used under strict supervision and/or restricted places

These are examples of the 5 rules of asepsis, except: 1. Any item used for patient care or that is visibly soiled must be considered "dirty" and "contaminated" 2. If the item has been cleaned with a detergent disinfectant, it is both clean and decontaminated 3. Sterile items are devices processed by steam, dry heat, ethylene oxide or other sterilization method to kill most organisms 4. Dirty, clean and sterile items must be separated at all times
