Pediatric Immunization NCLEX Questions Questions
Question 1 of 5
An example of a live vaccine is:
Correct Answer: A
Rationale: The varicella vaccine is a live attenuated vaccine containing a weakened varicella-zoster virus to prevent chickenpox. Choice B (influenza) includes both live (LAIV) and inactivated (IIV) forms, but the question implies a specific example, and IIV is more common. Choice C (Hepatitis B) is a recombinant subunit vaccine, and Choice D (Diphtheria) is a toxoid vaccine, both inactivated. Varicella is a clear, widely recognized live vaccine example.
Question 2 of 5
A provider has ordered Gardasil to be given to a prepubertal 9-year-old female. This vaccine should not be postponed until the child is in high school for which reason
Correct Answer: B
Rationale: Gardasil (HPV vaccine) is most effective before sexual activity begins (Choice B), as it prevents HPV infection, which is sexually transmitted. Vaccination at 9-12 years (per CDC) targets this pre-exposure window. Choice A is false—efficacy doesn’t decrease with age if unexposed. Choices C and D lack evidence linking efficacy to puberty or menses.
Question 3 of 5
What type of reaction commonly occurs after the diphtheria, tetanus, and acellular pertussis (DTaP) vaccine?
Correct Answer: A
Rationale: Swelling and tenderness at the injection site are common, expected side effects of DTaP, occurring in about 20-40% of recipients due to local inflammation from the vaccine antigens and adjuvants, per CDC data. Fever (Choice B) occurs but is less common (<10%) and rarely reaches 103°F. Continual crying (Choice C) and limpness (Choice D) are rare, severe reactions, not typical.
Question 4 of 5
What is the primary nursing intervention for a child with fever?
Correct Answer: D
Rationale: Monitoring and supportive care (e.g., hydration) is primary to assess fever cause (AAP). Antibiotics (Choice A) are for infections, antipyretics (Choice B) are secondary, and cold baths (Choice C) are outdated.
Question 5 of 5
The nurse is preparing to administer immunizations to a 6-month-old infant. Which vaccine is contraindicated for this age?
Correct Answer: A
Rationale: MMR, a live vaccine, is given at 12-15 months (CDC), not 6 months, due to maternal antibody interference. Hib, DTaP, and IPV are routine at 6 months.
