Pediatric Immunity NCLEX Questions Questions
Question 1 of 5
For consent to be considered valid it must contain all of these elements except:
Correct Answer: A
Rationale: Valid informed consent requires voluntariness (Choice B), adequate information about risks and benefits (Choice C), and mental capacity to understand and decide (Choice D). However, the client does not need to be 18 years of age (Choice A) for consent to be valid; minors can consent if emancipated, mature (per local laws), or via parental/guardian consent for vaccines. Age is not a universal requirement, making it the exception.
Question 2 of 5
During a routine pediatric visit, a 12-month-old patient will need which of the following vaccines?
Correct Answer: B
Rationale: At 12 months, the CDC schedule includes Hib (dose 4), PCV (dose 4), MMR (dose 1), Varicella (dose 1), HepA (dose 1, with dose 2 at 18-24 months), and influenza (annually, 2 doses initially if first season). DTaP dose 4 is at 15-18 months, IPV dose 4 at 4-6 years, and RV completes by 8 months. Choice B matches the 12-15 month visit most closely. Choice C lacks MMR and Varicella, critical at this age.
Question 3 of 5
A 4-year-old child is receiving amoxicillin (Amoxil) to treat otitis media and is in the clinic for a well-child checkup on the last day of antibiotic therapy. The provider orders varicella (Varivax); mumps, measles, and rubella (MMR); inactivated polio (IPV); and diphtheria, tetanus, and acellular pertussis (DTaP) vaccines to be given. Which action by the nurse is correct?
Correct Answer: A
Rationale: Antibiotics like amoxicillin don’t interfere with vaccine efficacy or safety, so all vaccines (MMR, Varivax, IPV, DTaP) can be administered as ordered at the 4-6 year visit (Choice A). Choice B is unnecessary—live vaccines (MMR, Varivax) aren’t affected by antibiotics. Choice C is overly cautious, and Choice D (aspirin) is inappropriate due to Reye’s syndrome risk.
Question 4 of 5
A pregnant woman passes antibodies to her unborn baby through the placenta to protect against certain diseases. About how long does this natural immunity last after birth?
Correct Answer: D
Rationale: Maternal antibodies, passed via the placenta (passive immunity), typically protect infants for about 6 months, though this varies by disease and antibody type (e.g., measles protection may last up to 12 months). None of the options (1, 2, or 5 years) accurately reflect this duration. 'None of the above' (Choice D) is correct, as the typical range is shorter than 1 year, often 3-6 months, per CDC and immunological data.
Question 5 of 5
Which milestone typically occurs first in pediatric development?
Correct Answer: C
Rationale: Rolling over occurs at 2-6 months, the earliest motor milestone listed (AAP). Crawling (6-12 months), walking (12-18 months), and speaking (words, 12 months) follow later, making Choice C correct.
