  1. A patient develops urticaria and facial angioedema 10 minutes after receiving an influenza vaccine. What is the most appropriate initial intervention?

    Answer: Administer epinephrine 1:1000 IM into the anterolateral thigh

    Angioedema combined with urticaria following vaccination indicates anaphylaxis, requiring immediate IM epinephrine as first-line treatment.

  2. Which of the following best describes the correct epinephrine dose for anaphylaxis in an adult weighing 80 kg?

    Answer: 0.3 mg IM of 1:1000 solution

    Adults and children over 30 kg receive 0.3 mg (0.3 mL) of epinephrine 1:1000 administered intramuscularly.

  3. After administering epinephrine for anaphylaxis during vaccination, how long should the patient be monitored before considering discharge?

    Answer: At least 4 hours or until fully stable

    Biphasic anaphylaxis can occur hours after the initial reaction, so patients must be monitored for at least 4 hours or until clinically stable.

  4. A 4-year-old child (18 kg) receives a vaccine and develops anaphylaxis. What is the correct epinephrine dose?

    Answer: 0.01 mg/kg IM of 1:1000, max 0.5 mg

    Pediatric epinephrine dosing is 0.01 mg/kg IM of the 1:1000 solution, not exceeding 0.5 mg per dose.

  5. Which vaccine reaction is characterized by fever, seizures, and hypotonic-hyporesponsive episode (HHE) and is most commonly associated with which vaccine?

    Answer: DTaP vaccine

    HHE (sudden hypotonia, pallor, and unresponsiveness) is most commonly reported after whole-cell pertussis-containing vaccines, including DTaP.

  6. When a patient loses consciousness immediately after vaccination, what is the first priority action?

    Answer: Assess airway, breathing, and circulation and determine if the cause is vasovagal or anaphylactic

    Rapid assessment of airway, breathing, and circulation distinguishes a vasovagal syncope from anaphylaxis, which guides definitive treatment.

  7. A vaccinee begins wheezing and complaining of throat tightness 5 minutes post-injection. What ACIP-recommended action takes priority over all others?

    Answer: Inject epinephrine IM into the anterolateral thigh immediately

    Respiratory symptoms (wheezing, throat tightness) following vaccination indicate anaphylaxis, and IM epinephrine is the singular priority intervention.
