Which of the following actions is NOT part of the typical instrument processing sequence?

• A. Patient charting.
• B. Sterilization.
• C. Decontamination.
• D. Storage.

Answer: (A)

The main idea here is how instruments are reprocessed before reuse. A typical instrument processing sequence includes decontamination (initial cleaning to remove bioburden), sterilization (killing all microorganisms), and storage (keeping instruments sterile until use). Charting, on the other hand, is administrative documentation about the patient and treatment, done in the patient record or chairside, not in the instrument reprocessing workflow. So charting is not part of the processing sequence, while decontamination, sterilization, and storage are integral steps.
