Cleaning And Decontamination Quiz! Trivia

To prevent aerosols, it is recommended to brush items below the surface of the water. This is because when items are brushed above the water surface, it can cause the release of small droplets called aerosols. These aerosols can contain harmful particles or pathogens that can be inhaled or contaminate the surrounding environment. By brushing items below the water surface, the aerosols are minimized, reducing the risk of exposure to potentially harmful substances.

The explanation for the given correct answer is that cavitation is indeed the mechanical process by which an ultrasonic cleaner works. Cavitation refers to the formation and implosion of tiny bubbles in a liquid due to high-frequency sound waves. These bubbles collapse rapidly, creating shock waves and high-pressure jets that effectively clean surfaces. Therefore, the statement is true.

This statement is false. Instruments received from surgery and tagged for repair should be cleaned before they are sent for repair. Cleaning the instruments before repair ensures that any biological material or debris is removed, preventing the buildup of contaminants and potential infection risks. It is important to maintain proper hygiene and cleanliness standards for all surgical instruments, including those that require repair.

Automatic washers clean using a spray-force action called impingement. This means that water is sprayed with force onto the surfaces being cleaned, effectively removing dirt and stains. Impingement is a common method used in automatic washers to ensure thorough cleaning. Therefore, the statement "Automatic washers clean using a spray-force action called impingement" is true.

The statement suggests that pre-cleaning is not necessary for items that will be processed in a mechanical cleaner because of the cavitation and impingement action. However, this is not true. Pre-cleaning is still necessary before using a mechanical cleaner to remove large debris or dirt that may interfere with the cleaning process. So, the correct answer is False.

The given statement is false because there are indeed methods available to verify cleaning process outcomes. These methods may include visual inspection, use of cleaning agents or solutions that leave a residue or change color upon contact with dirt or contaminants, and the use of specialized equipment such as swabs or test strips to detect the presence of specific substances. Additionally, advanced technologies such as ATP (adenosine triphosphate) testing can be used to measure the cleanliness of surfaces by detecting organic matter. Therefore, it is incorrect to state that there are no methods available to verify cleaning process outcomes.

Powered surgical instruments should not be cleaned using a mechanical cleaning process. Instead, they should be manually cleaned to ensure proper cleaning and to prevent damage to the instruments. Mechanical cleaning processes, such as ultrasonic cleaning, can cause the instruments to become damaged or corroded. Therefore, it is important to follow the manufacturer's instructions for cleaning and sterilizing powered surgical instruments.

Horizontal work surfaces in the decontamination area should not be cleaned and disinfected once per day. The correct answer is False. It is important to clean and disinfect horizontal work surfaces in the decontamination area more frequently than once per day to maintain a clean and safe environment. Regular cleaning and disinfection help prevent the spread of pathogens and ensure the effectiveness of the decontamination process.

Instruments with lumens should always be soaked in a vertical position because this allows for proper drainage and prevents the accumulation of debris or fluid inside the lumen. Soaking them in a horizontal position can lead to inadequate cleaning and potential contamination. Therefore, the statement is false.

The statement claims that all sonic cleaners have a decontamination cycle. However, this is not necessarily true as not all sonic cleaners are equipped with a decontamination cycle. Some may have different features or functions, and not all models or brands offer the same capabilities. Therefore, the statement is false.
