1.
Which of the following statement is correct?
Correct Answer
D. Decontamination should occur before cleaning.
Explanation
Decontamination should occur before cleaning because decontamination is the process of removing or neutralizing contaminants, such as bacteria, viruses, or toxic substances, from an item or surface. Cleaning, on the other hand, refers to the removal of visible dirt, dust, or debris. By decontaminating first, any potential harmful substances are eliminated, making the subsequent cleaning process more effective in removing physical impurities.
2.
Does successful sterilization begin with?
Correct Answer
B. Decontaminaion
Explanation
Successful sterilization begins with decontamination. Decontamination is the process of removing or reducing the number of microorganisms and their presence on surfaces or objects. It is an essential step before sterilization as it helps to eliminate any potential sources of contamination and ensures that the sterilization process is effective. Cleaning, packing, and sterilization are subsequent steps that follow decontamination in the sterilization process.
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 because they will provide specific guidelines on how to properly clean and maintain the device. These instructions may include information on which cleaning agents to use, how to apply them, and any precautions that need to be taken. By following the manufacturer's instructions, you can ensure that the device is cleaned effectively without causing any damage or voiding the warranty.

A Pyrogen is a?
Correct Answer
A. Fever inducing organism
Explanation
A pyrogen is a fever-inducing organism. Pyrogens are substances that can cause a rise in body temperature, leading to fever. They can be produced by certain bacteria, viruses, or other microorganisms. When pyrogens enter the body, they stimulate the release of chemicals called cytokines, which in turn trigger the hypothalamus to raise the body's temperature. This immune response helps the body fight off infections and other illnesses. Therefore, a pyrogen is not an antibiotic-resistant organism, virus, or prion, but rather a specific type of organism that induces fever.
5.
A biofilm can form in any?
Correct Answer
B. Non-sterile water enviroment
Explanation
A biofilm is a community of microorganisms that attach to a surface and form a protective matrix. It can form in any non-sterile water environment because these environments provide favorable conditions for microorganisms to attach and grow. Sterile water environments are free from microorganisms, so biofilm formation is unlikely. Enzyme foam and gel products are not typically suitable environments for biofilm formation as they are designed to inhibit the growth of microorganisms. Therefore, the correct answer is non-sterile water environment.
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
The correct answer is to contain soiled materials in a closed cart, covered bin, and identify them with a biohazard label. This ensures that the soiled materials are securely contained, preventing any potential contamination or spread of infectious agents. The closed cart and covered bin provide an additional barrier to protect individuals from coming into direct contact with the soiled materials. The biohazard label serves as a visual warning, alerting individuals to the potential hazards associated with the materials and reminding them to handle them with caution.
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
A fluid resistant face mask is not required when loading mechanical washers in the decontamination area because the main purpose of a face mask is to protect against respiratory droplets and airborne particles. In this scenario, the mechanical washers are not likely to generate any respiratory hazards, so a face mask is not necessary. However, a fluid resistant gown, extra protective gloves, and a face shield may still be needed to protect against potential splashes or spills of hazardous fluids.
8.
The detergent best suited for heavy orthopedic soils is?
Correct Answer
C. Lipolytic enyzmatic detergent
Explanation
Lipolytic enzymatic detergent is the best suited for heavy orthopedic soils because it contains enzymes that specifically break down and remove fatty and oily substances. Orthopedic soils often include bodily fluids and greasy residues, which can be effectively dissolved and removed by the lipolytic enzymatic detergent. Neutral pH detergent may not be strong enough to tackle heavy soils, while proteolytic enzyme detergent is more suitable for protein-based soils. Acid detergent is not designed to target orthopedic soils specifically.
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 complex channels that require a brush of the appropriate size to effectively remove debris and ensure thorough cleaning. Using a brush that is too small or too large may not reach all areas, leading to inadequate cleaning and potential contamination. Therefore, selecting the correct brush size is crucial for successful cleaning of lumened devices.
10.
To remove stubborn stains from instruments it is recommended to use?
Correct Answer
C. Non-Abrasive cleaner
Explanation
Non-abrasive cleaner is recommended to remove stubborn stains from instruments because abrasive cleaners can potentially damage the surface of the instruments. Non-abrasive cleaners are gentle yet effective in removing stains without causing any harm to the instruments. They are designed to be safe for use on delicate surfaces and materials. Therefore, using a non-abrasive cleaner is the best option to ensure that the instruments are cleaned thoroughly without causing any damage.
