What is the proper sequence for decontaminating instruments before sterilization?

• A. Rinse, dry, pre-clean, then package.
• B. Pre-clean to remove bioburden, rinse, and dry before packaging and sterilization.
• C. Package, then sterilize without cleaning.
• D. Sterilize first, then clean.

Answer: (B)

The proper approach is to pre-clean to remove bioburden, then rinse, and dry before packaging and sterilization. Cleaning first removes organic material and microorganisms so the sterilant can contact all surfaces effectively. Rinsing washes away residues from cleaning agents and debris, and drying ensures the instruments are moisture-free, which protects package integrity and prevents corrosion. Packaging is done after cleaning so the instruments stay clean during sterilization, and sterilization follows on clean, dry instruments. Skipping cleaning or attempting to sterilize dirty instruments would leave soil and bioburden that shield microbes and reduce sterilization effectiveness.
