#9
What is the purpose of decontamination in medical instrument processing?
To kill microorganisms
ExplanationDecontamination eliminates harmful microorganisms to prevent infection.
#10
What is the purpose of using enzymatic detergents in the cleaning process of medical instruments?
To break down organic matter
ExplanationEnzymatic detergents effectively break down organic debris for thorough cleaning.
#11
Which of the following is a characteristic of an effective cleaning agent for medical instruments?
Non-corrosive
ExplanationNon-corrosive agents prevent damage to delicate instruments.
#12
What is the purpose of performing routine inspections on medical instruments?
To check for manufacturing defects
ExplanationInspections ensure instruments are free from defects that may affect performance or safety.
#13
What is the purpose of passivation in the cleaning and decontamination process of medical instruments?
To remove surface contaminants and enhance corrosion resistance
ExplanationPassivation improves instrument longevity by enhancing resistance to corrosion.
#14
Which of the following is an example of a non-critical medical instrument?
Patient gown
ExplanationNon-critical instruments only contact intact skin.
#15
Which of the following methods is NOT suitable for disinfecting medical instruments?
Rinsing with water
ExplanationWater rinsing alone does not effectively disinfect instruments.
#16
What is the primary objective of packaging medical instruments after cleaning and sterilization?
To protect from contamination until use
ExplanationPackaging safeguards instruments from contamination until needed for use.
#17
Which of the following is a common indicator used to verify the effectiveness of autoclave sterilization?
Color change
ExplanationColor indicators change when conditions for effective sterilization are met.
#18
What is the primary function of a washer-disinfector in medical instrument processing?
To automate the cleaning process
ExplanationWasher-disinfectors automate cleaning, enhancing efficiency and reliability.
#19
Which of the following is an example of a critical medical instrument?
Endoscope
ExplanationCritical instruments directly contact sterile tissue or vascular system.
#20
Which of the following is an example of a semi-critical medical instrument?
Ultrasound probe
ExplanationSemi-critical instruments contact mucous membranes or non-intact skin.
#21
What is the recommended temperature for autoclaving medical instruments for sterilization?
121°C (250°F)
ExplanationAutoclaving at this temperature effectively sterilizes instruments.
#22
What is the purpose of using detergents with neutral pH in the cleaning process of medical instruments?
To prevent instrument discoloration
ExplanationNeutral pH detergents prevent discoloration or damage to instrument surfaces.
#23
Which of the following is a recommended method for storing cleaned and sterilized medical instruments?
In a clean, dry, and well-ventilated area
ExplanationProper storage conditions maintain instrument sterility and integrity.
#24
Which of the following is NOT a recommended practice for handling contaminated medical instruments?
