  1. What is the single most important infection control measure between patients at a vaccine clinic?

    Answer: Performing hand hygiene between each patient

    Hand hygiene is universally recognized by WHO and CDC as the most effective single measure to prevent healthcare-associated infection transmission.

  2. If a vaccine vial's rubber stopper appears cored or damaged, the administrator should:

    Answer: Discard the vial and report the incident to a supervisor

    A cored or damaged stopper indicates possible contamination; the vial must be discarded and the event reported per facility infection control protocols.

  3. When administering multiple vaccines simultaneously at the same visit, injection sites should be separated by at least:

    Answer: 1 inch (2.5 cm)

    ACIP recommends injection sites be at least 1 inch (2.5 cm) apart to allow monitoring of site-specific local reactions from each individual vaccine.

  4. Which needle gauge and length is standard for intradermal (ID) vaccine administration?

    Answer: 27-gauge, 3/8–5/8-inch needle

    Intradermal injections require a fine, short needle—typically 27 gauge, 3/8 to 5/8 inch—to deliver the vaccine into the dermis at a shallow 5–15 degree angle.

  5. How frequently should surfaces in a vaccine administration area be cleaned and disinfected?

    Answer: Between each patient and at the end of each session

    High-touch surfaces in immunization areas should be cleaned and disinfected between patients and at the end of each session to prevent cross-contamination.

  6. OSHA's sharps injury log must include all of the following EXCEPT:

    Answer: The name of the patient on whom the device was used

    OSHA's sharps injury log does not require the patient's name; it must document the device type, work area, and incident description while protecting worker confidentiality.

  7. A vaccine administrator receives a splash of blood to the eye during vaccine preparation. What is the immediate first action?

    Answer: Immediately flush the affected eye with clean water or sterile saline for at least 15 minutes

    Immediate irrigation of the mucous membrane with clean water or sterile saline for at least 15 minutes is the first step for any blood splash to the eye.
