Which sterilization method uses steam under pressure to achieve microbial kill?
Steam autoclaving
Ethylene oxide gas
Dry heat
Low-temperature chemical sterilant
Steam autoclaving uses pressurized saturated steam to effectively kill a broad spectrum of microorganisms by denaturing proteins. Other methods like ethylene oxide, dry heat, and chemical sterilants do not rely on pressurized steam.
Which personal protective equipment item protects the eyes from fluid splashes during decontamination?
Protective goggles
Surgical mask
Shoe covers
Disposable apron
Protective goggles form a seal around the eyes to prevent fluid splashes from causing injury or contamination. Masks, shoe covers, and aprons protect other areas but do not safeguard the eyes effectively.
What is the first step in the instrument decontamination process?
Removal of gross soil
Final sterilization
Packaging
Documentation
The removal of gross soil is essential as an initial step to reduce bioburden and improve the efficacy of subsequent cleaning and sterilization. Packaging and sterilization occur after cleaning, and documentation follows sterilization.
When should surgical instruments be inspected for defects or damage?
Before cleaning
After sterilization
During use in surgery
During packaging
Inspecting instruments before cleaning ensures damaged or malfunctioning items are identified and segregated before further processing. Inspection after sterilization or during packaging does not prevent instrument damage or risk during cleaning.
Which packaging material is appropriate for steam sterilization in an autoclave?
Medical-grade sterilization wrap
Standard plastic zip-lock bag
Red biohazard disposal bag
Aluminum foil
Medical-grade sterilization wrap is porous enough to allow steam penetration while maintaining a microbial barrier after sterilization. Zip-lock bags, biohazard bags, and aluminum foil do not provide validated steam sterilization parameters.
Which class of chemical indicator is designed to be placed inside a sterilization pack to monitor multiple sterilization parameters?
Class 5 integrating indicator
Class 1 process indicator
Class 2 Bowie-Dick indicator
Class 3 single-parameter indicator
Class 5 integrating indicators respond to time, temperature, and sterilant conditions within a pack, ensuring parameters were met. Other classes monitor fewer or external parameters only.
What are the recommended temperature and exposure time for a standard gravity-displacement steam sterilization cycle?
121°C for 30 minutes
121°C for 15 minutes
132°C for 4 minutes
134°C for 5 minutes
Gravity-displacement steam sterilization typically operates at 121°C for 30 minutes to achieve proper microbial kill, especially for wrapped and hollow instruments. Higher temperatures are associated with pre-vacuum cycles.
Which biological indicator organism is most commonly used to monitor steam sterilization efficacy?
Geobacillus stearothermophilus
Bacillus subtilis
Clostridium tetani
Staphylococcus aureus
Geobacillus stearothermophilus spores are highly heat-resistant and serve as the standard biological indicator for steam sterilization processes. Other organisms are not used for steam sterilization monitoring.
What documentation must be completed after each sterilization cycle to meet regulatory compliance?
Sterilizer cycle record sheet
Instrument usage log
Daily equipment maintenance log
Staff training documentation
The sterilizer cycle record sheet documents critical parameters such as time, temperature, pressure, and indicator results for each cycle, which is required for compliance. Other logs serve different purposes.
What is the recommended water temperature range for manual cleaning of surgical instruments?
35°C to 45°C
20°C to 25°C
10°C to 20°C
60°C to 70°C
Water temperatures between 35°C and 45°C optimize detergent activity without denaturing proteins or creating hazards. Cooler water reduces cleaning efficacy, and hotter water can cause protein coagulation.
What is the maximum recommended relative humidity for a sterile storage area to prevent moisture-related contamination?
Less than 60%
Less than 80%
Less than 90%
Less than 50%
Maintaining relative humidity below 60% helps prevent moisture buildup that can compromise packaging integrity and lead to microbial growth. Higher humidity levels increase risk of contamination.
Which sterilization method is most appropriate for a heat-sensitive flexible endoscope?
Ethylene oxide gas sterilization
Dry heat sterilization
Steam sterilization
Boiling water immersion
Ethylene oxide gas sterilization operates at low temperatures compatible with heat-sensitive instruments like flexible endoscopes. Steam and dry heat require high temperatures that can damage delicate components.
During assembly, how should sharp or pointed instruments be positioned in a tray?
Handles facing outward and sharp points down
Blades interlocked
Points facing upwards
Handles and points randomly oriented
Positioning sharp points down and handles outward minimizes injury risk and allows even sterilant penetration. Random orientation or upward-pointing blades increase injury hazards.
What is the primary purpose of the Bowie-Dick test in a pre-vacuum steam sterilizer?
Detect air leaks and inadequate air removal
Verify biological indicator efficacy
Measure drying cycle effectiveness
Test chemical indicator placement
The Bowie-Dick test detects residual air in a pre-vacuum sterilizer by observing steam penetration through a test pack. It does not directly assess biological or chemical indicator performance.
Which packaging configuration enhances steam penetration for hinged instrument trays?
Wrapping the tray in two separate sterilization wraps
Sealing the tray in a plastic container
Using a single layer of paper
Wrapping tightly with aluminum foil
Using two wraps provides an effective microbial barrier while allowing steam to penetrate between layers and throughout the tray. Plastic containers and foil can inhibit steam flow.
A biological indicator shows microbial growth after a steam sterilization cycle. What is the most appropriate action?
Repeat the sterilization cycle and investigate the cause
Release the instruments since chemical indicators passed
Discard the biological indicator and use a new one next time
Document the growth and continue using the sterilizer
Microbial growth in a biological indicator indicates sterilization failure and requires immediate cycle repeat and root cause analysis. Chemical indicators alone cannot confirm sterility.
A Bowie-Dick test fails repeatedly on a pre-vacuum sterilizer. Which issue is most likely causing the failure?
Inadequate vacuum pulse or leak in chamber
Chemical indicator misplacement
Excessive sterilizer temperature
Overloading with heavy instruments
A failed Bowie-Dick test typically indicates air removal problems such as leaks or inadequate vacuum pulses. Overloading can affect results but primary cause is air retention.
According to most regulatory guidelines, how long should sterilization cycle records be retained for audit purposes in a hospital setting?
2 years
1 year
5 years
10 years
Hospitals commonly retain sterilization records for at least 2 years to comply with regulatory and accreditation requirements for traceability. Shorter or longer periods are less common standards.
When validating a new low-temperature chemical sterilant, which parameter is most critical to confirm its efficacy?
Concentration of active sterilizing agent
Shelf life of the packaging materials
Ambient humidity in the sterilization room
Staff training completion rate
The concentration of the active agent directly impacts the microbial kill rate and is essential to validate before clinical use. Packaging shelf life and environmental factors are secondary to efficacy.
A sterile peel pouch shows delamination after autoclave exposure. What quality assurance measure should be implemented?
Retrain staff on proper pouch sealing and handling
Increase autoclave temperature
Switch to chemical sterilization
Double-wrap the peel pouches
Delamination suggests improper folding or sealing technique; retraining staff ensures correct pouch handling. Altering sterilization parameters or methods does not address packaging errors.
