Pediatric Immunization NCLEX Questions Quizlet Questions
Question 1 of 5
Sudden stimulus causes the arms to fly up and out is:
Correct Answer: D
Rationale: The Moro reflex (startle reflex) occurs when a sudden stimulus causes the arms to extend outward then flex inward, common in newborns. Tonic neck (A) involves head-turning asymmetry. Rooting (B) aids feeding. Gag (C) prevents choking.
Question 2 of 5
A 16-year-old boy... decreasing performance in school... more irritable and irresponsible... Which of the following disorders is the most likely cause?
Correct Answer: E
Rationale: Substance use explains irritability, irresponsibility, and declining grades with a friend group change, common in adolescence. Bipolar (A) and depression (C) may affect mood but lack social shift specificity. Conduct (B) involves aggression, not necessarily grades.
Question 3 of 5
Which vaccine is given as a series of 3 doses?
Correct Answer: A
Rationale: The hepatitis B vaccine is administered as a 3-dose series (typically at 0, 1, and 6 months) for full immunization in infants, children, and adults. Choice B (MMR) is a 2-dose series (at 11-12 months and 4-6 years). Choice C (Hepatitis A) is a 2-dose series (6 months apart). Choice D (HPV) can be a 2- or 3-dose series depending on age at initiation (2 doses if started before age 15, 3 doses if started at 15 or older), but hepatitis B is the most consistently recognized 3-dose series among these options.
Question 4 of 5
Following immunization, an anaphylactic response would usually occur within:
Correct Answer: C
Rationale: Anaphylaxis is a rapid-onset allergic reaction, typically occurring within 5-30 minutes after vaccination, though it can rarely extend to an hour. This is due to the immediate release of mediators like histamine following IgE-mediated hypersensitivity. Choice A (12-24 hours) and D (2-4 hours) are far too delayed for anaphylaxis, which is an acute emergency. Choice B (60-90 minutes) may capture some late-onset cases but exceeds the usual timeframe for most reactions.
Question 5 of 5
The temperature of vaccine refrigerators must be checked and logged:
Correct Answer: B
Rationale: CDC guidelines mandate that vaccine refrigerator temperatures be checked and logged twice daily (morning and evening) to ensure they remain within 2°C-8°C. This frequent monitoring detects excursions promptly, preventing vaccine spoilage. Choice A (once a week) and D (twice a week) are insufficient, and Choice C (once daily) misses potential overnight fluctuations, making Choice B the standard practice.
