#1
Which of the following is an essential step in surgical instrument decontamination?
Using a high-level disinfectant
ExplanationHigh-level disinfectants are crucial for eliminating pathogens during instrument decontamination.
#2
What is the purpose of pre-cleaning surgical instruments?
To remove blood, tissue, and other debris
ExplanationPre-cleaning is necessary to ensure effective subsequent sterilization by removing contaminants.
#3
Which of the following methods is commonly used for sterilizing surgical instruments?
Autoclaving
ExplanationAutoclaving is a widely employed method for achieving sterilization through high-pressure steam.
#4
What does the term 'bioburden' refer to in the context of surgical instrument decontamination?
The amount of bacteria and other microorganisms on the instruments
ExplanationBioburden signifies the microbial load present on instruments before decontamination.
#5
What is the purpose of using enzymatic detergents in surgical instrument cleaning?
To break down organic material
ExplanationEnzymatic detergents are effective in breaking down organic residues on surgical instruments.
#6
Which of the following is NOT a recommended practice for handling contaminated surgical instruments?
Rinsing instruments with cold water immediately after use
ExplanationRinsing with cold water can set proteinaceous material, making subsequent cleaning more challenging.
#7
What is the purpose of using a washer-disinfector in the decontamination process?
To mechanically clean and disinfect instruments
ExplanationWasher-disinfectors efficiently remove debris and pathogens from surgical instruments.
#8
Which of the following is a recommended method for storing sterilized surgical instruments?
Storing them in a clean, dry, and well-ventilated area
ExplanationProper storage conditions help maintain the sterility of surgical instruments after sterilization.
#9
What is the purpose of using a biological indicator in sterilization processes?
To verify that the sterilization process has been effective
ExplanationBiological indicators confirm the efficacy of sterilization by assessing microbial kill.
#10
Which regulatory body provides guidelines for infection control in healthcare settings?
Centers for Disease Control and Prevention (CDC)
ExplanationThe CDC offers comprehensive guidelines for infection control practices in healthcare.
#11
Which of the following is an example of a critical surgical instrument?
Surgical scissors
ExplanationCritical instruments like surgical scissors come into contact with sterile tissues or the vascular system.
#12
What does the term 'flash sterilization' refer to?
Sterilizing instruments for immediate use in urgent situations
ExplanationFlash sterilization is a rapid process used to sterilize instruments for immediate use.
#13
Which of the following is an example of a semi-critical surgical instrument?
Blood pressure cuff
ExplanationSemi-critical instruments contact mucous membranes or non-intact skin but not sterile tissues.
#14
What is the minimum recommended temperature for autoclaving surgical instruments?
121°C (250°F)
ExplanationAutoclaving at 121°C (250°F) ensures effective sterilization of surgical instruments.
#15
Which of the following is NOT a factor influencing the effectiveness of sterilization?
Altitude
ExplanationAltitude does not significantly affect the sterilization process.
#16
Which of the following is NOT a recommended method for transporting contaminated surgical instruments?
Exposing instruments to open air during transport
ExplanationTransporting instruments openly can lead to contamination and compromise sterility.
