What is the correct sequence for cleaning and reprocessing reusable medical equipment?

• A. Cleaning to remove debris, disinfection to reduce pathogens, then sterilization if required, followed by proper drying and storage
• B. Disinfection only
• C. Sterilization, disinfection, then cleaning
• D. Cleaning only

Answer: (A)

The sequence starts with cleaning to remove debris and organic matter, because residue can shield microbes and interfere with later steps. If debris stays on the instrument, subsequent disinfection or sterilization won’t work effectively, and some pathogens can survive. After cleaning, disinfection lowers the number of remaining pathogens on the surface, reducing infection risk for anyone who handles or uses the instrument. Sterilization is performed when the device is intended for contact with sterile body sites or breached tissues, and it aims to eliminate all forms of life; but it relies on a clean surface to be reliable. Finally, drying and proper storage prevent recontamination and help maintain the instrument’s readiness for use. So the best sequence is cleaning first, then disinfection, followed by sterilization if required, and finishing with drying and storage.
