    Instruments can be pre-soaked in holding solution immediately after use to

    • A.

      Kill bacterial spores

    • B.

      Prevent drying of blood and organic matter

    • C.

      Safely use the instruments without further processing

    • D.

      Eliminate the need for ultrasonic cleaning

    Correct Answer
    B. Prevent drying of blood and organic matter
    Explanation
    Pre-soaking instruments in a holding solution immediately after use helps prevent drying of blood and organic matter. This is important because when blood and organic matter dry on instruments, it becomes much more difficult to clean them effectively. Pre-soaking helps to keep the debris moist, making it easier to remove during the subsequent cleaning process. By preventing drying, the instruments can be safely used without further processing, reducing the risk of contamination. However, pre-soaking alone is not sufficient to kill bacterial spores or eliminate the need for ultrasonic cleaning.

    Which of the following shows that the sterilization process was successful?

    • A.

      Readings on autoclave guages

    • B.

      Timer indicates full cycle

    • C.

      Spore tests

    • D.

      Visual examination of heat indicating tape

    Correct Answer
    C. Spore tests
    Explanation
    Spore tests are used to confirm the effectiveness of the sterilization process. These tests involve placing bacterial spores on a test strip or in a vial and subjecting them to the sterilization process. Afterward, the spore tests are analyzed to determine if any viable spores survived the process. If no spores are found, it indicates that the sterilization process was successful in killing all microorganisms, making it a reliable indicator of the process's effectiveness.

    • C.

      Is not considered a carrier of hepatitis B

    • D.

      Is an infectious carrier of hepatitis B

    Correct Answer
    D. Is an infectious carrier of hepatitis B
    Explanation
    The presence of HBeAg (Hepatitis B e antigen) and HBsAg (Hepatitis B surface antigen) in a medical laboratory report suggests that the person is an infectious carrier of hepatitis B. This means that they are currently infected with the hepatitis B virus and are capable of transmitting the infection to others. It does not provide any information about whether the person has received a hepatitis B vaccination or is currently undergoing treatment for hepatitis B.

    If rag wheels are to be reused, what would be the BEST means of decontamination?

    • A.

      Spray with phenolic alcohol between uses.

    • B.

      Soak in glutaraldehyde

    • C.

      Wipe off with iodophor.

    • D.

      Autoclave.

    Correct Answer
    D. Autoclave.
    Explanation
    Autoclaving is the most effective means of decontamination for reusing rag wheels. Autoclaving uses high pressure and steam to sterilize and kill any microorganisms present on the surface of the rag wheels. This method ensures that the rag wheels are thoroughly cleaned and safe for reuse. Spraying with phenolic alcohol, soaking in glutaraldehyde, or wiping off with iodophor may not provide the same level of sterilization as autoclaving.
