Decontamination & Cleaning Procedures Flashcards

What is the recommended action if an instrument cannot be fully disassembled for cleaning?

Answer: Follow the device IFU and use appropriate cleaning tools for all accessible areas

The manufacturer's Instructions for Use (IFU) must always be followed; instruments with complex designs require specific tools and techniques to clean accessible areas.

What is the primary purpose of a pre-soak solution in the decontamination workflow?

Answer: To prevent soil from drying and hardening on instrument surfaces during transport

Pre-soak solutions keep soil moist and begin enzymatic breakdown, making subsequent mechanical or manual cleaning more effective.

A CS technician notices rust-like staining on stainless steel instruments after washing. What is the most likely cause?

Answer: Mineral deposits from hard water or pitting corrosion

Rust-like staining on stainless steel is typically caused by mineral deposits from hard water or early-stage pitting corrosion from chemical damage.

How often should washer-disinfector efficacy be tested according to best practice?

Answer: Daily, using process challenge devices or soil test carriers

Daily testing with soil test carriers or process challenge devices verifies that the washer-disinfector is operating correctly and consistently.

Why must detergent pH and concentration be strictly monitored in automated washers?

Answer: Incorrect levels can damage instruments or leave residues that interfere with sterilization

Too much or too little detergent, or incorrect pH, can pit instrument surfaces, leave residues, or fail to adequately remove bioburden.

Which of the following best describes the 'Spaulding Classification' relevance to decontamination?

Answer: It determines the required level of reprocessing (critical, semi-critical, noncritical) based on intended use

The Spaulding Classification system categorizes medical devices by risk level to guide the minimum required reprocessing level.
