IAHCSMM Decontamination & Cleaning Procedures

Question 1

What is the first step in the decontamination process for reusable surgical instruments?

Accepted Answer

Point-of-use pre-cleaning

Answer

Point-of-use pre-cleaning removes gross soil immediately after use, preventing biofilm formation and making subsequent cleaning more effective.

Question 2

Which water quality is recommended for the final rinse of surgical instruments in an automated washer?

Accepted Answer

Deionized or softened water

Answer

Deionized or softened water is recommended for final rinses to prevent mineral deposits and spotting on instrument surfaces.

Question 3

What pH range is generally recommended for enzymatic detergents used in instrument cleaning?

Accepted Answer

6.0–8.0 (near neutral)

Answer

Near-neutral pH enzymatic detergents (6.0–8.0) effectively break down proteins and organic soil without damaging instrument materials.

Question 4

What is the purpose of using a lint-free cloth when manually cleaning instruments?

Accepted Answer

To prevent leaving fibers that could interfere with sterilization

Answer

Lint-free cloths prevent fiber contamination that could interfere with sterilization efficacy or be introduced into a surgical site.
