Free MDRAO Identification Questions and Answers — Questions and Answers

Question 1: The area where soiled equipment is received, disassembled to their smallest components, and decontaminated:

Decontamination Area (Correct answer)
Sterilization Area
Central Supply Area
Assembly Area

Correct answer: Decontamination Area

Explanation: The decontamination area is where soiled equipment is received, disassembled, and decontaminated to remove organic and inorganic contaminants before further processing. This area is crucial for ensuring that medical devices are properly prepared for cleaning, disinfection, and sterilization.

Question 2: The inspected, tested, reassembled, and packaged area:

Sterile Holding Area
Decontamination Area
Assembly Area (Correct answer)
Central Supply Area

Correct answer: Assembly Area

Explanation: The Assembly Area is where inspected, tested, reassembled, and packaged medical devices are prepared before being moved to the sterile holding area or directly to user areas. This area ensures that devices are correctly assembled, functional, and appropriately packaged for use in patient care areas.

Question 3: What works by creating mutations in DNA which either kills or makes the bacteria inviable?

Indirect contact
Peracetic acid sterilization
Irradiation sterilization (Correct answer)
Scaling

Correct answer: Irradiation sterilization

Explanation: Irradiation sterilization works by creating mutations in DNA, which can lead to bacterial death or make the bacteria inviable. This process damages the DNA of microorganisms, preventing them from reproducing and causing infections, thus achieving sterilization of medical devices.

Question 4: Pre-rinse (rehydrate blood and remove soil), wash (detergent), rinse, disinfection:

Washer disinfector cycles: 5
Washer disinfector cycles: 6
Washer disinfector cycles: 4 (Correct answer)
Washer disinfector cycles: 8

Correct answer: Washer disinfector cycles: 4

Explanation: The typical sequence of cycles in a washer disinfector includes pre-rinse (rehydrating blood and removing soil), wash with detergent, rinse, and disinfection. This process usually involves four cycles to ensure thorough cleaning and disinfection of medical devices.

Question 5: It is unable to kill fungi, non-enveloped viruses, mycobacteria, or spores:

RLD
LLD (Correct answer)
LLE
HLD

Correct answer: LLD

Explanation: LLD stands for Low-Level Disinfection, which is unable to kill fungi, non-enveloped viruses, mycobacteria, or spores. This type of disinfection is effective against vegetative bacteria and some enveloped viruses but not against the mentioned microorganisms.

Question 6: Bacterial cells that will produce a spore coat to resist heat, drying, and chemicals:

Lethal Factor
Protective Antigen
Spore Coat (Correct answer)
Exosporium

Correct answer: Spore Coat

Explanation: Bacterial cells that will produce a spore coat to resist heat, drying, and chemicals are referred to as spore coats. The spore coat acts as a protective layer around the bacterial spore, providing resistance to harsh conditions and enabling the spore to survive in hostile environments.

Question 7: How often should cart washers be cleaned?

Weekly, descaled monthly
Daily, descaled weekly (Correct answer)
Monthly, descaled annually
Twice a week, descaled once a month

Correct answer: Daily, descaled weekly

Explanation: Cart washers should be cleaned daily to maintain hygiene and prevent the buildup of contaminants. Additionally, they should be descaled weekly to remove mineral deposits and ensure optimal performance. Regular cleaning and descaling help extend the lifespan of the equipment and maintain effective cleaning results.

Question 8: Suppliers have 180 days to update the ______:

history
labels (Correct answer)
stigma
SDS

Correct answer: labels

Explanation: Labels on chemical products must be updated within 180 days if there are any changes to the information provided. This ensures that users have access to accurate and up-to-date information about the contents and potential hazards of the products they handle.

Question 9: Suppliers have 90 days to update the ______:

history
labels
stigma
SDS (Correct answer)

Correct answer: SDS

Explanation: Safety Data Sheets (SDS) provide detailed information about the properties of chemicals, including potential hazards and safety precautions. Suppliers are required to update SDS within 90 days if there are any changes to the information provided on the sheets. This ensures that users have access to accurate and up-to-date safety information for the chemicals they handle.

Question 10: What is WSIB?

Globally Harmonized System
Safety Data Sheets
Centers For Disease Control And Prevention
Workplace Safety and Insurance Board (Correct answer)

Correct answer: Workplace Safety and Insurance Board

Explanation: The Workplace Safety and Insurance Board (WSIB) is an Ontario government agency responsible for providing workplace safety and insurance coverage for workers and employers in the province of Ontario, Canada. It administers the workers' compensation system, ensuring that workers who are injured on the job receive appropriate medical care and compensation, while also promoting workplace health and safety initiatives.

Question 11: The area where sterilized items are stored to prevent contamination prior to being transported to the user areas:

Decontamination Area
Sterilization Area
Sterile Holding Area (Correct answer)
Assembly Area

Correct answer: Sterile Holding Area

Explanation: The Sterile Holding Area is where sterilized items are stored temporarily to prevent contamination before they are transported to user areas for use in patient care. This area provides a controlled environment to maintain the sterility of the items until they are needed, ensuring they remain safe for patient use.
