Instruments that have been contaminated should be treated by

• A. Sterilization
• B. Disinfection
• C. Sanitization
• D. PPE

Answer: (C)

When instruments are contaminated, the goal is to render them completely free of viable microorganisms. Sterilization achieves this by using validated methods that destroy all life forms, including bacterial spores. This level of decontamination is necessary for instruments that enter sterile tissues or the bloodstream, where even a single microbe could cause serious infection. Disinfection lowers the microbial load but does not guarantee complete elimination, so it’s not sufficient for invasive instruments. Sanitization refers to cleaning to reduce soil and microbial counts, but it does not achieve sterility on its own. PPE is protective gear and does not decontaminate instruments. In practice, contaminated instruments are cleaned first and then sterilized to ensure full decontamination.
