The correct sequence for processing reusable instruments is: (1) Decontamination (immediate post-use treatment to make items safe to handle by removing gross soil and reducing microbial load, typically using enzymatic cleaners); (2) Cleaning (thorough removal of all organic material and residues using detergent, water, and mechanical action like brushing or ultrasonic cleaning); (3) Disinfection or Sterilization (killing microorganisms to appropriate level—disinfection eliminates most pathogens except bacterial spores, while sterilization eliminates all microorganisms including spores); and (4) Storage (proper handling and storage to maintain sterility until use). This sequence is critical for patient safety—cleaning must precede sterilization because organic material can protect microorganisms from sterilizing agents. Each step has specific methods, equipment, and quality control measures. Nurses must follow facility protocols and manufacturers' instructions for each instrument type to ensure effective processing and prevent healthcare-associated infections.
