Decontamination method 2 for blood or other infectious materials on items?

• A. Sterilizing
• B. Cleaning then sterilizing
• C. Disinfection then cleaning
• D. Cleaning only

Answer: (B)

When decontaminating items that have blood or other infectious materials on them, the right approach is to remove contaminants first and then apply a method that eliminates all microbes. Cleaning before sterilizing matters because the debris and organic material can shield microbes and block the sterilant or heat from penetrating evenly. Once the item is clean, sterilization can effectively reach and destroy even hardy organisms, including spores. Relying on disinfection first isn’t enough for these items, since disinfection doesn’t guarantee the destruction of spores and may leave some pathogens behind. Cleaning only leaves harmful contaminants in place, which is not acceptable for instruments that contact blood or infectious material. So the best sequence is to clean the item, then sterilize it.
