    Winch of the following statements about endoscopes is true?`

    • Not all endoscopes can be processed in the AER

    • Ultrasonic cleaning is the process of choice for endoscopes

    • Flexible endoscopes are not easily damaged

    • All endoscopes should be steam sterilized

    Correct Answer
    A. Not all endoscopes can be processed in the AER
    Explanation
    The Automated Endoscope Reprocessor (AER) is a machine used for cleaning and disinfecting endoscopes. However, not all endoscopes can be processed in the AER. Some endoscopes may have complex designs or delicate components that cannot withstand the automated cleaning process. Therefore, it is important to carefully assess each endoscope and determine whether it can be safely processed in the AER or if it requires alternative cleaning methods.

    When arranging plastic-paper pouches in the sterilizer,the pouches should be arranged:

    • Paper to plastic

    • Paper to paper

    • Plastic to plastic

    • The way in which the most packages can be placed in the sterilizer

    Correct Answer
    A. Paper to plastic
    Explanation
    The correct answer is "paper to plastic" because when arranging plastic-paper pouches in the sterilizer, it is important to place the paper side facing the plastic side. This is because the paper side is more susceptible to heat and moisture, so placing it against the plastic side helps to protect it during the sterilization process. Additionally, this arrangement ensures that the plastic side is facing outward, which makes it easier to identify the contents of each pouch after sterilization.
