What should you do before washing instruments to ensure they are free of large contaminants?

• A. Mechanical cleaning
• B. Rinsing with critical water
• C. Pre-rinsing/pre-soaking
• D. Sorting instruments

Answer: (C)

Pre-rinsing or pre-soaking instruments is a crucial step before washing to ensure that they are free of large contaminants. This process helps to loosen and dislodge any soil, blood, or tissue debris that might be adhering to the instruments, making it easier to clean them thoroughly during the subsequent washing phase. Pre-rinsing or soaking in water helps to prevent contaminants from drying onto the instruments, which can complicate the cleaning process and may even lead to the formation of biofilms.

While other options might contribute to the overall cleaning process, they do not directly address the initial removal of large contaminants as effectively as pre-rinsing or pre-soaking. Mechanical cleaning typically refers to processes that utilize machines or devices to aid in cleaning but may not focus on the initial loosening of debris. Rinsing with critical water is more about the final rinse during the cleaning process, rather than the preparation before washing. Sorting instruments, although important for organization and ensuring that items are cleaned appropriately according to their classification, does not directly contribute to the removal of contaminants before washing.
