1.
Which of the following statement is correct?
Correct Answer
D. Decontamination should occur before cleaning.
Explanation
Decontamination should occur before cleaning because the process of decontamination involves removing or neutralizing harmful substances, such as bacteria, viruses, or chemicals, from an item or surface. Once the item has been decontaminated, the cleaning process can then be carried out to remove any dirt, debris, or non-harmful substances. This sequence ensures that the item is thoroughly disinfected before any further cleaning is done, reducing the risk of spreading contaminants during the cleaning process.
2.
Successful sterilization begins with?
Correct Answer
B. Decontaminaion
Explanation
Decontamination is the first step in the process of sterilization. It involves removing or reducing the number of microorganisms on an object or surface to a safe level. Cleaning is necessary before decontamination to remove visible dirt and debris. Once the object is clean, it can be decontaminated to eliminate any remaining microorganisms. After decontamination, the object can then be properly packed to maintain its sterility. Sterilization, on the other hand, is the final step in the process and involves killing or removing all microorganisms, including spores, from an object or surface.
3.
The first thing to do when cleaning a device is to?
Correct Answer
C. Follow the device manufacturer's instruction
Explanation
When cleaning a device, it is important to follow the device manufacturer's instructions. This is because different devices have different cleaning requirements and using the wrong method or detergent could damage the device. The manufacturer's instructions will provide guidance on the appropriate cleaning techniques and products to use, ensuring that the device is cleaned effectively and safely. Following the manufacturer's instructions also helps to maintain the device's warranty and prolong its lifespan.
4.
A Pryogen is a?
Correct Answer
A. Fever inducing organism
Explanation
A pyrogen is a fever-inducing organism. Pyrogens are substances that can cause an increase in body temperature, leading to fever. This can be due to the presence of certain bacteria or other microorganisms in the body, which trigger an immune response and result in an elevated body temperature. Pyrogens can also be produced by the body itself as a response to infection or inflammation. Overall, a pyrogen is any substance or organism that can cause fever.
5.
A biofilm can form in any?
Correct Answer
B. Non-sterile water enviroment
Explanation
Biofilms can form in any non-sterile water environment. Biofilms are complex microbial communities that adhere to surfaces and are encased in a self-produced matrix. They can form in various environments, including water systems, such as pipes, tanks, and water treatment facilities. Non-sterile water environments provide the necessary nutrients and conditions for microbial growth and the formation of biofilms. Sterile water environments, on the other hand, lack the presence of microorganisms, making it unlikely for biofilms to form. Enzyme foam and gel products are not mentioned in the question and are therefore not relevant to the formation of biofilms.
6.
When transporting soiled materials, they should be?
Correct Answer
D. Contained in a closed cart, covered bin and identified with a biohazard label.
Explanation
When transporting soiled materials, it is important to contain them in a closed cart and covered bin to prevent any spillage or leakage. Additionally, the materials should be identified with a biohazard label to alert others of potential risks. This ensures that the materials are handled and disposed of properly, minimizing the risk of contamination or infection.
7.
When loading mechanical washers in the decontamination area, which type of personal protective is not required?
Correct Answer
B. Fluid resistant face mask
Explanation
When loading mechanical washers in the decontamination area, a fluid resistant face mask is not required. This is because the main purpose of a face mask is to protect against respiratory droplets and airborne particles, which may not be a significant risk when loading mechanical washers. However, a fluid resistant gown, extra protective gloves, and a face shield are still necessary to protect against potential exposure to fluids and other contaminants during the loading process.
8.
The detergent best suited for heavy orthopedic soils is?
Correct Answer
C. Lipolytic enyzmatic detergent
Explanation
A lipolytic enzymatic detergent is the best choice for heavy orthopedic soils because it contains enzymes that specifically break down and remove lipid-based stains and soils. Orthopedic soils can include bodily fluids, oils, and greases, which are all lipid-based substances. The enzymes in the detergent target and break down these substances, effectively removing them from the fabric or surface being cleaned. This makes a lipolytic enzymatic detergent highly effective in removing heavy orthopedic soils.
9.
One of the most important factors in successful cleaning of lumened devices is?
Correct Answer
B. Selection of the correct diameter and length cleaning brush
Explanation
The correct answer is the selection of the correct diameter and length cleaning brush. This is because lumened devices have narrow and intricate channels that can be difficult to clean. Using a cleaning brush with the correct diameter and length ensures that all areas of the lumen are reached and effectively cleaned. This helps to remove any debris or contaminants that may be present, ensuring the device is thoroughly cleaned and ready for use.
10.
To remove stubborn stains form instruments it is recommended to use?
Correct Answer
C. Non-Abrasive cleaner
Explanation
A non-abrasive cleaner is recommended to remove stubborn stains from instruments because it is gentle enough to not damage the surface of the instruments while effectively removing the stains. Abrasive cleaners or tools like wire brushes can potentially scratch or damage the instruments, so a non-abrasive cleaner is the best option to ensure the instruments remain in good condition.
