Read the first 7 High-Level Disinfection Processes flashcards as text

  1. Ortho-phthalaldehyde (OPA) has what primary advantage over glutaraldehyde for high-level disinfection?

    Answer: Faster acting at room temperature with less irritation

    OPA works faster than glutaraldehyde (12 minutes vs. 20 minutes) and produces fewer fumes, reducing occupational health concerns.

  2. When performing high-level disinfection in an automated endoscope reprocessor (AER), which step must be verified manually before loading the scope?

    Answer: That thorough manual cleaning and leak testing have been completed

    Manual cleaning and leak testing must be completed before placing the scope in an AER, as the AER does not compensate for inadequate pre-cleaning.

  3. A flexible endoscope fails a leak test. What should be done before proceeding with HLD?

    Answer: Remove the scope from service and send it for repair

    A scope that fails leak testing must be taken out of service and sent for repair to prevent internal damage from HLD chemicals and cross-contamination.

  4. Which personal protective equipment (PPE) is required when handling glutaraldehyde HLD solutions?

    Answer: Gloves, gown, and eye/face protection at minimum

    At minimum, gloves, a fluid-resistant gown, and eye/face protection are required when handling glutaraldehyde due to its toxic and sensitizing properties.

  5. What is the purpose of rinsing an endoscope thoroughly with sterile or filtered water after HLD?

    Answer: To remove residual disinfectant that could harm patients

    Residual HLD chemicals can cause mucosal injury in patients, so thorough rinsing with sterile or filtered water after HLD is essential.

  6. Which statement about peracetic acid (PAA) used in AERs is correct?

    Answer: PAA is typically single-use and disposed of after each cycle

    Peracetic acid used in most AER systems is formulated as a single-use product and discarded after each cycle, unlike reusable HLD solutions.

  7. At what point should a logbook entry for HLD processing be completed?

    Answer: Immediately after each scope is processed

    Documentation must be completed immediately after each scope is processed to ensure accurate traceability and compliance with infection control standards.
