Answers | Latest Verison | 2024/2025 |
Correct & Verified
Why are instruments sorted by type and function before cleaning?
✔✔ To prevent damage and ensure appropriate cleaning methods are used.
What is the significance of using a chemical integrator in sterilization?
✔✔ To monitor multiple parameters and verify sterilization effectiveness.
Why must sterilizers undergo routine calibration and validation?
✔✔ To ensure accurate and reliable performance.
How should sterile packages be handled to maintain sterility?
✔✔ By touching only the outside and avoiding any contact with unsterile surfaces.
Why is proper air removal essential in steam sterilization?
✔✔ Air pockets can prevent steam from reaching all surfaces, leading to sterilization failure.
1
,What should be done if a chemical spill occurs in the sterile processing department?
✔✔ Follow the spill response procedure, including using PPE and proper cleanup methods.
Why must rigid containers be inspected before use in sterilization?
✔✔ To check for damage or wear that could compromise the sterility of the contents.
What is the purpose of heat-sealing pouches in sterile packaging?
✔✔ To create a tamper-proof barrier that maintains sterility.
Why is it necessary to check expiration dates on sterilized items?
✔✔ To ensure they are still considered sterile and safe for use.
How should non-disposable brushes used for cleaning instruments be maintained?
✔✔ They should be cleaned and disinfected after each use to avoid cross-contamination.
Why is it important to disassemble instruments before cleaning?
✔✔ To expose all surfaces to the cleaning agents and ensure thorough decontamination.
2
,What should be done if an instrument is found to be damaged during inspection?
✔✔ It should be removed from service and sent for repair or replacement.
Why are chemical indicators used in sterilization processes?
✔✔ To verify that the sterilant has penetrated the package and reached all contents.
What is the preferred method of sterilization for heat-sensitive equipment?
✔✔ Low-temperature gas plasma or ethylene oxide sterilization.
Why is it necessary to keep the decontamination area under negative air pressure?
✔✔ To prevent the spread of contaminants to other areas.
How often should biological testing be performed on sterilizers?
✔✔ At least weekly, and with every load containing implants.
What is the purpose of performing routine maintenance on sterilization equipment?
✔✔ To ensure the equipment functions effectively and consistently.
3
, Why should sterile items be stored at least 8-10 inches off the floor?
✔✔ To avoid contamination from dust and cleaning activities.
What is the importance of drying instruments thoroughly before packaging?
✔✔ Moisture can lead to microbial growth and compromise sterility.
Why is it important to label sterile packages with the load number and date?
✔✔ To provide traceability in case of a sterilization recall.
How should instruments with hinges be positioned during sterilization?
✔✔ In the open position to allow steam or gas to reach all surfaces.
What is the main role of the ultrasonic cleaner in sterile processing?
✔✔ To remove soil and debris from instruments using cavitation.
Why must chemical disinfectants be stored in a well-ventilated area?
✔✔ To prevent inhalation of harmful fumes by personnel.
