What is the primary purpose of sterilization in sterile processing?
To kill microorganisms, including bacterial spores
To remove visible soil and debris
To ensure instruments are lubricated
To make packaging waterproof
Sterilization is intended to eliminate all forms of microbial life, including bacterial spores, to ensure patient safety. Removal of soil is part of cleaning, not sterilization. Lubrication is a maintenance step that follows decontamination. Proper packaging supports sterility assurance but isn’t the primary goal of sterilization. CDC Sterilization Guidelines
Which color change on process indicator tape indicates that a package has been processed in a steam sterilizer?
White stripes turning black
Yellow to white
Blue to green
Green to yellow
Process indicator tape designed for steam sterilization has stripes that turn from white to black when the correct temperature and steam conditions are achieved. Other color shifts are associated with different sterilants or are incorrect. This visible change confirms that the load was exposed to the sterilization parameters. AAMI Standards
Which type of cleaning agent is most effective at breaking down protein-based soils on surgical instruments?
Neutral pH detergent
Enzymatic detergent
Abrasive cleaner
Phenolic disinfectant
Enzymatic detergents contain proteases that specifically break down protein soils, making them highly effective in pre-cleaning instruments. Neutral pH detergents may not target proteins as efficiently. Abrasive cleaners can damage delicate instrument surfaces. Phenolic disinfectants are designed to kill microbes, not to remove soils. FDA Reprocessing Guidance
What type of water is recommended for steam sterilizer operation to prevent scale buildup and corrosion?
Tap water
Distilled or deionized water
Softened water
Hard well water
Distilled or deionized water is recommended for steam sterilizers because it has low mineral content, preventing scale buildup and corrosion inside the chamber. Tap, softened, or hard well water contains minerals that can accumulate and damage the sterilizer. Using the correct water type extends equipment life and maintains sterilization efficacy. AAMI Water Quality Guidelines
Which of the following is the first step in the decontamination process for surgical instruments?
Donning appropriate personal protective equipment (PPE)
Rinsing instruments with water
Inspecting instruments for damage
Packaging instruments for sterilization
The first step in decontamination is to don appropriate PPE to protect staff from exposure to potentially infectious materials. Rinsing, inspection, and packaging occur later in the cleaning, inspection, and sterilization stages, respectively. Proper PPE reduces the risk of injury and pathogen transmission. NIOSH Healthcare Guidelines
Which sterilization method relies on vaporized hydrogen peroxide in a low-temperature cycle?
Ethylene oxide
Hydrogen peroxide gas plasma
Peracetic acid immersion
Formaldehyde vapor
Hydrogen peroxide gas plasma systems use vaporized hydrogen peroxide in a low-temperature cycle to sterilize heat- and moisture-sensitive devices. Ethylene oxide also operates at low temperature but uses EO gas. Peracetic acid is a liquid immersion process, and formaldehyde vapor is a different gas-based sterilant. AAMI Sterilization Standards
Which biological indicator organism is used to verify steam sterilization efficacy?
Bacillus atrophaeus
Geobacillus stearothermophilus
Bacillus subtilis
Clostridium sporogenes
Geobacillus stearothermophilus spores are the most heat-resistant biological indicators for steam sterilization and are used to validate steam cycles. Bacillus atrophaeus is used for dry heat and ethylene oxide processes. Bacillus subtilis and Clostridium sporogenes are used in other sterilization and disinfection validations. CDC BI Guidelines
What is the recommended maximum load weight for a standard tabletop steam sterilizer?
10 pounds
25 pounds
50 pounds
100 pounds
Manufacturer guidelines typically limit a tabletop steam sterilizer load to 25 pounds to ensure adequate steam penetration and proper sterilization. Overloading may prevent steam from reaching all surfaces. Always consult the equipment manual for specific load capacities. AAMI Equipment Guidelines
According to AAMI standards, what is the maximum recommended number of wrapping layers for steam sterilization packaging?
One layer
Two layers
Three layers
Four layers
AAMI ST79 recommends no more than two layers of wrapping for steam sterilization to ensure adequate steam penetration and drying. Excessive layers can trap air and moisture, compromising sterility. Proper wrapping technique is critical for process success. AAMI ST79
What is the shelf life of a properly sterilized and stored package with intact packaging?
6 months
1 year
Indefinite, if the packaging integrity is maintained
30 days
Sterilized packages have an indefinite shelf life as long as the packaging remains intact, dry, and undamaged, according to AAMI and CDC guidance. Time-based expiration dates are not required unless specified by facility policy. Integrity checks are essential before use. CDC Storage Guidelines
If a chemical indicator inside a package fails to change color after steam sterilization, what is the appropriate action?
Use the instruments and record the deviation
Reprocess the package and check sterilizer function
Ignore it since biological indicators are the only requirement
Send the package to surgery for immediate use
A failed chemical indicator suggests the package did not meet sterilization parameters and must be reprocessed. Ignoring it or using instruments could risk patient safety. Biological indicators complement but do not replace chemical indicators inside each load. Equipment function should be verified before reprocessing. AAMI Sterilization Monitoring
Immediate use steam sterilization (flash) is intended primarily for which scenario?
Routine daily processing
High-volume manufacturing
Emergency situations in the operating room
Long-term storage of instruments
Immediate use steam sterilization, or flash sterilization, is reserved for urgent or emergency situations in the OR when a delay in instrument availability would compromise patient care. It is not intended for routine or long-term processing due to reduced packaging and monitoring. AORN Guidelines
What is the standard gravity displacement cycle time and temperature for sterilizing wrapped goods in a steam sterilizer?
4 minutes at 132°C
10 minutes at 121°C
27 minutes at 121°C
16 minutes at 134°C
The standard gravity displacement cycle for wrapped goods typically runs at 121°C for 27 minutes to ensure effective steam penetration and sterilization. Higher temperatures and shorter times apply to pre-vacuum cycles. Always follow equipment validation data. CDC Sterilization Cycles
Which sterilization parameters are recommended for prion decontamination of surgical instruments?
121°C for 27 minutes
132°C for 4 minutes
134°C for 18 minutes
132°C for 20 minutes
Prion decontamination requires more stringent steam parameters; many guidelines recommend 134°C for 18 minutes in a pre-vacuum sterilizer to inactivate prion proteins. Standard cycles at lower temperatures or shorter durations are not sufficient for prion elimination. WHO Prion Guidelines
How often should biological indicators be used for routine monitoring of a steam sterilizer?
Per load
Daily
Weekly
Monthly
AAMI and CDC recommend using a biological indicator at least weekly for each sterilizer to validate the effectiveness of the sterilization process. Per-load testing is impractical and monthly is not frequent enough to ensure ongoing performance. Daily chemical indicators complement weekly BI testing. CDC BI Use
What is the required pore size for filters in rigid sterilization container systems to maintain sterility?
0.45 microns
0.8 microns
0.22 microns
0.1 microns
Rigid container systems require 0.22 micron filters to prevent microbial ingress while allowing air removal and steam penetration. Filters larger than 0.22 microns may allow bacteria to pass, and smaller pores impede steam transmission. Proper filter integrity is crucial for sterility assurance. AAMI Container Systems
What is the minimum recommended contact time for high-level disinfectants in automated endoscope reprocessors (AER) for flexible endoscopes?
5 minutes
20 minutes
45 minutes
90 minutes
Most AAMI and manufacturer instructions specify a minimum 20-minute contact time for high-level disinfectants in automated endoscope reprocessors at specified temperatures to ensure pathogen elimination. Shorter times may not achieve high-level disinfection, and longer times are not typically required. AAMI Endoscope Reprocessing
