CQI in device decontamination: the role of washer indicators Circle the one correct answer:


1. When a wash indicator shows a failing result, CSSD should: A. Review the cycle selection and rerun the washer load


B. Visually inspect the instruments and determine if they should be re-washed


C. Investigate the process and deter- mine the root cause of failure


D. B and C E. A and C


2. Washer indicators are used to: A. Verify the cleaning process of automated washers


B. Eliminate the need for visual in- spection of instruments after the automated cleaning process


C. Be part of a quality control process to determine whether automated washers meet a predetermined standard of efficacy


D. A and C E. B and C


3. Washing indicators use live spores and soil as a challenge to the auto- mated washing process. A. True B. False


4. When implementing washer indica- tors into an CSSD’s quality assur- ance plan: A. Begin the benchmark process with a washing indicator placed in the most easily accessible position in a fully loaded instrument basket


B. Begin the benchmark process with a washing indicator placed in the most challenging position in a fully loaded instrument basket


C. Begin the benchmark process by placing the washer indicator in an empty washing system.


D. Begin the benchmark process by placing the washer indicator in the middle rack with a fully loaded basket.


5. A typical washer/disinfector pro- cess equation includes these pri- mary factors: A. Time, temperature, and chemis- tries


B. Time, temperature, and impinge- ment (mechanical action)


C. Time, temperature, impingement and chemistries


D. Time, impingement, ultrasonic action and chemistries

B. The use of washer indicators to establish an optimal cycle


C. Following all manufacturers’ instructions for use of equipment and indicators


D. Differences in a system’s impinge- ment action that may require more strategic selection of clean- ing chemistries


E. All of the above


7. Factors that can contribute to washer indicator failure are: A. Chemistry selection and delivery issues


B. Impingement arm failure and inappropriate water temperature selection


C. Overloaded instrument trays D. All of the above E. A and B


8. professional standards organiza­ tions and cleaning indicator manu facturers provide baseline recommendations as to the use of indicators, but each facility deter- mines how they are used in their CSSD, and how often. A. True B. False


9. A washer indicator failure result is difficult to determine, and the presence of soil must be measured to indicate a pass/fail. A. True B. False


10. To pass a washer indicator using a low impingement washer you would need to: A. Use a less aggressive chemistry (neutral pH)


B. Use a more aggressive chemistry (high alkaline pH)


C. Run two cycles to ensure thorough cleaning


D. a and c E. None of the above
