  1. What needle length is recommended for intramuscular (IM) vaccine administration in the deltoid of an average adult weighing 130–152 lbs?

    Answer: 1 inch (25 mm)

    CDC/ACIP recommends a 1-inch (25 mm) needle for deltoid IM injections in adults of average weight; length increases for heavier individuals.

  2. According to Standard Precautions, gloves should be worn during vaccine administration:

    Answer: Whenever contact with blood or body fluids is possible

    Standard Precautions require gloves whenever contact with blood or body fluids is anticipated, regardless of the patient's known infection status.

  3. What is the preferred method of hand hygiene before administering vaccines when hands are not visibly soiled?

    Answer: Alcohol-based hand sanitizer containing at least 60% alcohol

    CDC recommends alcohol-based hand rubs (≥60% alcohol) as the preferred method of hand hygiene when hands are not visibly soiled.

  4. Which practice best prevents needlestick injuries in an immunization setting?

    Answer: Using safety-engineered needles and activating the safety device immediately after withdrawal

    OSHA requires safety-engineered needles and mandates immediate activation of safety devices after needle withdrawal to minimize needlestick risk.

  5. Used needles and syringes must be discarded immediately into:

    Answer: Puncture-resistant, leak-proof sharps containers

    OSHA requires all contaminated sharps to be discarded in puncture-resistant, leak-proof sharps containers to prevent injury and exposure.

  6. At what angle should the needle be inserted for an intramuscular (IM) injection?

    Answer: 90 degrees

    IM injections are administered at a 90-degree angle to the skin to ensure the vaccine is deposited into muscle tissue.

  7. To maintain sterility when accessing a multi-dose vaccine vial, the administrator should:

    Answer: Wipe the rubber stopper with a new alcohol swab before each puncture

    The rubber stopper of a multi-dose vial must be cleaned with a fresh alcohol swab before each access to prevent microbial contamination.
