  1. Which personal protective equipment (PPE) combination is required when handling a patient with active pulmonary tuberculosis in the OR?

    Answer: N95 respirator, gown, gloves, and eye protection

    Airborne precautions for TB require a fit-tested N95 or higher respirator along with gown, gloves, and eye protection.

  2. Which action best prevents the transmission of Clostridioides difficile (C. diff) in the perioperative environment?

    Answer: Handwashing with soap and water rather than alcohol-based hand rub

    C. diff spores are resistant to alcohol; soap and water physically remove spores from hands and are required for C. diff precautions.

  3. A surgical technologist has a needlestick injury during a case. What is the first action to take?

    Answer: Immediately remove glove, wash the wound with soap and water, and report to supervisor

    Immediate wound washing with soap and water followed by prompt reporting initiates the exposure response protocol.

  4. What is the recommended room air exchange rate per hour in an operating room to reduce airborne contamination?

    Answer: A minimum of 15 air changes per hour, with at least 3 of outdoor air

    AORN and CDC guidelines recommend a minimum of 15 total air changes per hour with at least 3 fresh outdoor air changes in the OR.

  5. Which type of wound is considered a Class III (contaminated) surgical wound?

    Answer: Open traumatic wound with gross spillage from the GI tract

    Class III wounds include open traumatic wounds, operations with major breaks in sterile technique, or gross GI spillage.

  6. Which statement about sterile field maintenance is correct regarding a team member who steps away from the sterile field?

    Answer: The team member must be considered unsterile and cannot return to the sterile field without re-gowning and re-gloving

    Once a scrubbed team member steps away from the sterile field, their sterility cannot be guaranteed and full re-gowning and re-gloving is required.

  7. Preoperative chlorhexidine gluconate (CHG) bathing of a surgical patient is most beneficial for which purpose?

    Answer: Reducing skin bacterial burden to lower SSI risk

    Preoperative CHG bathing reduces colonization on the patient's skin, which is associated with decreased SSI rates.
