SPD - Sterile Processing Department Technician Quality Assurance and Safety Questions and Answers 1 — Questions and Answers
Question 1: A Class 5 chemical integrating indicator is used to monitor a steam sterilization cycle. After the cycle, the technician observes that the indicator has not reached the 'accept' window. What does this result signify?
- The sterilizer is functioning correctly, but the pack was too dense.
- The chemical indicator is expired and gave a false reading.
- One or more critical parameters of the steam sterilization cycle were not met. (Correct answer)
- The cycle was successful, as some color change is always acceptable.
Correct answer: One or more critical parameters of the steam sterilization cycle were not met.
A Class 5 chemical integrating indicator is designed to react to all critical parameters of a specific sterilization process (time, temperature, and steam). If it fails to reach the 'accept' zone, it indicates that one or more of these essential conditions were not achieved, meaning the load cannot be considered sterile.
Question 2: An SPD technician receives a loaner instrument tray from a vendor for a scheduled surgery. Which of the following is the MOST critical initial step for the technician to take to ensure patient safety?
- Immediately sterilize the tray to ensure it is ready for the procedure.
- Verify that the vendor has provided the manufacturer's Instructions for Use (IFU) for decontamination and sterilization. (Correct answer)
- Assume the instruments are clean and proceed directly to assembly and packaging.
- Weigh the tray to ensure it does not exceed the 25-pound limit.
Correct answer: Verify that the vendor has provided the manufacturer's Instructions for Use (IFU) for decontamination and sterilization.
Before any processing can begin, the SPD must have the manufacturer's specific, written, and FDA-cleared Instructions for Use (IFU). The IFU provides the validated parameters for cleaning, decontamination, assembly, and sterilization, which are essential for ensuring the device can be made safe for patient use. Processing without the IFU is a major safety risk.
Question 3: According to AAMI ST79, what is the recommended minimum frequency for performing a biological indicator (BI) process challenge device (PCD) test on a steam sterilizer?
- Monthly and in every implant load.
- At least weekly, but preferably daily, and in every implant load. (Correct answer)
- Only when a new type of instrument is introduced.
- Once per day, regardless of the load contents.
Correct answer: At least weekly, but preferably daily, and in every implant load.
AAMI ST79 recommends that routine efficacy monitoring of steam sterilizers be performed at least weekly, with a preference for daily testing. Additionally, every load containing an implantable device must be monitored with a BI PCD.
Question 4: A positive biological indicator (BI) result occurs after a steam sterilization cycle. The technician has quarantined the load. What is the immediate next step in the recall procedure?
- Notify the operating room to retrieve any potentially affected items that were released.
- Assume the BI was faulty and re-run the same load without changes.
- Take the sterilizer out of service and wait for the biomedical engineer.
- Identify and recall all items processed in that sterilizer back to the last known negative BI. (Correct answer)
Correct answer: Identify and recall all items processed in that sterilizer back to the last known negative BI.
In the event of a positive BI, a recall must be initiated. The recall includes all items processed in the sterilizer since the last known negative (passed) BI test. This is because it's impossible to know exactly when the sterilizer began to fail. This 'window of liability' necessitates recalling all potentially non-sterile items.
Question 5: Which of the following workplace safety practices is mandated by OSHA's Bloodborne Pathogens Standard for the decontamination area of the SPD?
- Requiring all technicians to have at least five years of experience.
- Using only automated washer-disinfectors for all instruments.
- Providing and ensuring the use of appropriate Personal Protective Equipment (PPE). (Correct answer)
- Maintaining a room temperature below 60°F (15°C) to inhibit microbial growth.
Correct answer: Providing and ensuring the use of appropriate Personal Protective Equipment (PPE).
OSHA's Bloodborne Pathogens Standard (29 CFR 1910.1030) requires employers to protect workers from occupational exposure to blood or other potentially infectious materials. A key component of this standard is providing, at no cost to the employee, appropriate Personal Protective Equipment (PPE) such as gloves, fluid-resistant gowns, eye protection, and masks, and ensuring employees use it correctly.
Question 6: A key component of a quality management system in the Sterile Processing Department is documentation. Which of the following records is MOST critical for traceability and quality assurance?
- The daily work schedule of the technicians.
- A log of all staff birthdays and anniversaries.
- The purchase orders for new sterilization wrap.
- Sterilization load records with physical, chemical, and biological indicator results. (Correct answer)
Correct answer: Sterilization load records with physical, chemical, and biological indicator results.
Sterilization load records are essential for quality assurance and traceability. They provide documented proof that a specific load was subjected to a monitored sterilization cycle, linking the processed items to the cycle parameters, chemical indicator results, and biological indicator results. This documentation is critical in the event of a recall or for auditing purposes.
