Pediatric Immunization NCLEX Questions Questions
Question 1 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 2 of 5
The nurse is preparing to administer immunizations to a 6-month-old infant. Which vaccine is contraindicated for this age?

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.
