Pediatric Immunizations NCLEX Questions Questions
Question 1 of 5
An unexpected and undesirable response after an immunization is:
Correct Answer: B
Rationale: An adverse event is a broad term for any unexpected or undesirable health occurrence following immunization, which may or may not be causally related to the vaccine (e.g., fever, anaphylaxis). Choice A (side effect) refers to common, expected reactions (e.g., soreness). Choice C (allergy) and D (hypersensitivity) are specific immune-mediated reactions, subsets of adverse events, but not as encompassing as Choice B, which aligns with public health reporting (e.g., VAERS).
Question 2 of 5
An 18 year old patient is in the clinic to receive a tetanus vaccine after sustaining a laceration injury. The nurse learns that the patient, who works in a day care center, has not had any vaccines for more than 10 years. Which vaccine will the nurse expect to administer?
Correct Answer: D
Rationale: For an 18-year-old with a laceration and no vaccines for over 10 years, Tdap is recommended. It updates tetanus (Td) and adds pertussis protection, critical for daycare workers due to pertussis risk to infants. Td (Choice C) lacks pertussis, DT/DTaP (Choices A, B) are for children <7 years.
Question 3 of 5
Bacterial meningitis strikes babies more often than any other age group. Which vaccine will help prevent one previously common type of meningitis?
Correct Answer: B
Rationale: The Hib vaccine protects against *Haemophilus influenzae* type b, a major cause of bacterial meningitis in infants before widespread vaccination. Tetanus (Choice A) prevents lockjaw, HIV (Choice C) is a virus with no vaccine, and Varicella (Choice D) prevents chickenpox, none of which cause meningitis. Hib (Choice B) is correct per CDC.
Question 4 of 5
Which vaccination is commonly given to infants to prevent tuberculosis?
Correct Answer: B
Rationale: The BCG vaccine prevents severe TB (e.g., miliary TB) in infants in high-risk areas (WHO), though not routine in the U.S. Measles, polio, and mumps vaccines target other diseases, making Choice B correct.
Question 5 of 5
Which toy is most appropriate for a toddler to encourage fine motor skills?
Correct Answer: D
Rationale: Puzzles with large pieces enhance fine motor skills (grasping, coordination) in toddlers (1-3 years), per developmental guidelines. Blocks (Choice A) aid gross motor, others are less specific.
