#1. Why must items sterilized with EO go through aeration?
Correct Answer: To remove leftover EO gas
Explanation: Aeration removes residual EO gas, making instruments safe for patient use.
#2. How should a sterilizer chamber be loaded?
Correct Answer: Not overloaded
Explanation: Overloading blocks sterilant circulation and can prevent proper sterilization.
#3. Where should you find the required aeration time for a medical device?
Correct Answer: Device manufacturer’s Instructions for Use (IFU)
Explanation: The manufacturer’s IFU provides the correct aeration requirements for safe processing.
#4. Why is ethylene oxide (EO) used for some medical devices?
Correct Answer: It is safe for heat- and moisture-sensitive devices
Explanation: EO is designed for devices that cannot tolerate the high temperatures of steam sterilization.
#5. Who sets the permissible exposure limits (PELs) for sterilization chemicals?
Correct Answer: OSHA
Explanation: OSHA establishes exposure limits to help protect workers from hazardous chemicals.
#6. Which item is commonly sterilized using hydrogen peroxide?
Correct Answer: Telescopes
Explanation: Hydrogen peroxide is commonly used for heat-sensitive medical devices such as rigid telescopes.
#7. Which low-temperature sterilization method can penetrate long, narrow lumens?
Correct Answer: Ethylene oxide (EO)
Explanation: EO gas penetrates complex devices and long lumens effectively, making it useful for certain heat-sensitive instruments.
#8. Where can you verify whether a device is compatible with a specific sterilization process?
Correct Answer: Device manufacturer’s IFU
Explanation: The IFU specifies which sterilization methods are safe and approved for that device.
#9. What does “material compatibility” mean?
Correct Answer: The materials can safely withstand the sterilization process
Explanation: Not every material is compatible with every sterilization method. Always follow the manufacturer’s instructions.
#10. Why is proper training important before using low-temperature sterilization?
Correct Answer: Sterilants can be toxic if used incorrectly
Explanation: Low-temperature sterilization uses chemicals that require proper handling to protect both staff and patients.
