1. Question 1 of 10Which organization publishes ANSI/AAMI ST79, the comprehensive guide to steam sterilization in health care facilities?

   A.AAMIB.AORNC.OSHAD.FDA
   Show answer

   Answer: A. AAMI

   AAMI (the Association for the Advancement of Medical Instrumentation) writes consensus standards for sterile processing, including ST79. OSHA enforces worker safety, FDA clears medical devices, and AORN publishes perioperative nursing guidelines.

2. Question 2 of 10Which federal agency enforces the Bloodborne Pathogens Standard that protects sterile processing workers?

   A.CDCB.EPAC.FDAD.OSHA
   Show answer

   Answer: D. OSHA

   OSHA enforces the Bloodborne Pathogens Standard (29 CFR 1910.1030). CDC issues infection-prevention guidelines but does not enforce workplace rules; EPA registers disinfectants; FDA regulates medical devices.

3. Question 3 of 10Which agency registers the chemical disinfectants used on environmental surfaces such as countertops and carts?

   A.OSHAB.The Joint CommissionC.EPAD.HSPA
   Show answer

   Answer: C. EPA

   The EPA registers hard-surface disinfectants. FDA, not EPA, regulates the liquid chemical sterilants and high-level disinfectants used on critical and semicritical medical devices.

4. Question 4 of 10In which direction should instruments move through the sterile processing department?

   A.In whichever direction is shortest, as long as carts are coveredB.From decontamination to preparation and packaging, then sterilization and sterile storage, never backwardC.From preparation back to decontamination for a final rinseD.From sterile storage to decontamination for a second check before use
   Show answer

   Answer: B. From decontamination to preparation and packaging, then sterilization and sterile storage, never backward

   A one-way workflow from dirty to clean keeps contaminated items from crossing paths with clean and sterile ones. HSPA’s content outline lists one-way workflow under traffic control.

5. Question 5 of 10Compared with the clean areas next to it, what air pressure should the decontamination area have?

   A.Negative pressureB.Positive pressureC.Equal (neutral) pressureD.Positive during the day and negative at night
   Show answer

   Answer: A. Negative pressure

   Decontamination is kept at negative pressure so air flows into it and contaminated aerosols do not drift into clean areas. Preparation, packaging and sterile storage are kept at positive pressure.

6. Question 6 of 10Which of these is not acceptable for a technician working in the preparation and packaging area?

   A.Clean scrub attireB.A hair covering that contains all hairC.Short, natural fingernailsD.Artificial nails
   Show answer

   Answer: D. Artificial nails

   Artificial nails and nail extenders harbor microorganisms and can tear packaging, so they are not allowed. HSPA’s outline names artificial nails and jewelry under dress code standards.

7. Question 7 of 10A new detergent arrives in the department. Where will a technician find its hazards, required PPE and first-aid measures?

   A.The instrument count sheetB.The department’s par-level listC.The safety data sheet (SDS)D.The sterilizer load record
   Show answer

   Answer: C. The safety data sheet (SDS)

   OSHA’s Hazard Communication Standard requires a safety data sheet for every hazardous chemical, covering hazards, PPE, first aid, spills and disposal. The manufacturer’s instructions for use (IFU) explain how to use the product.

8. Question 8 of 10A chemical splashes into a technician’s eyes in decontamination. What should happen first?

   A.Finish the tray, then go to the eyewash stationB.Flush the eyes at the eyewash station for at least 15 minutes, then report the exposureC.Wipe the eyes with a dry towel and keep workingD.Rinse briefly with tap water and apply a neutralizing chemical
   Show answer

   Answer: B. Flush the eyes at the eyewash station for at least 15 minutes, then report the exposure

   Flushing starts immediately and continues for at least 15 minutes (the ANSI Z358.1 standard for eyewash stations), then the exposure is reported. Never apply a neutralizer to the eyes.

9. Question 9 of 10A department tracks how often immediate-use steam sterilization (IUSS) is used. What can a high rate point to?

   A.Not enough instrument sets or workflow problems, since IUSS should not replace adequate inventoryB.Better quality, because IUSS is the preferred method for every setC.Lower risk, because IUSS loads do not need monitoringD.Nothing; IUSS rates are not a quality measure
   Show answer

   Answer: A. Not enough instrument sets or workflow problems, since IUSS should not replace adequate inventory

   CDC says flash (immediate-use) sterilization should not be used for convenience, to avoid buying more instrument sets, or to save time. HSPA’s outline lists IUSS rates among quality assurance benchmarks.

10. Question 10 of 10Why does the department keep sterilizer records such as cycle printouts, load contents and biological indicator results?

    A.They are only needed for the sterilizer warrantyB.They are used to calculate staff overtimeC.They replace the need for biological indicatorsD.They prove each load met its parameters and let a recall be traced to specific items
    Show answer

    Answer: D. They prove each load met its parameters and let a recall be traced to specific items

    Records document that each cycle was monitored and released correctly. If a biological indicator later fails, lot numbers and load records let the department retrieve exactly the affected items.
