Pediatric Immunity NCLEX Questions Questions
Question 1 of 5
A child with IQ 50-70% is considered a severe form of mental retardation.
Correct Answer: B
Rationale: IQ 50–70 is mild mental retardation per DSM-5; severe is IQ 20–35. The ‘%’ may be a typo, but assuming 50–70, Option B (False) is correct.
Question 2 of 5
The measles, mumps, rubella and varicella (MMRV) is given to children at what age?
Correct Answer: C
Rationale: The MMRV vaccine, which combines measles, mumps, rubella, and varicella vaccines, is recommended for children at 12-15 months for the first dose, with a second dose at 4-6 years, per CDC guidelines. It is not given before 12 months because maternal antibodies may interfere with the live vaccine’s efficacy. Choice A (6 months), B (2 months), and D (4 months) are too early for MMRV; other vaccines (e.g., rotavirus, DTaP) are given at those ages instead.
Question 3 of 5
The use of epinephrine is contraindicated in clients who:
Correct Answer: B
Rationale: Epinephrine has no absolute contraindications in the context of anaphylaxis, as it is a life-saving intervention. The benefits outweigh risks in all populations, including pregnant women (Choice A), immunocompromised individuals (Choice C), and those over 65 (Choice D). Relative cautions (e.g., cardiac disease) may apply in non-emergent settings, but in anaphylaxis, epinephrine is universally indicated regardless of patient status, making Choice B correct.
Question 4 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 5 of 5
Active immunity occurs when:
Correct Answer: A
Rationale: Active immunity occurs when the immune system produces antibodies in response to an antigen, such as after natural infection (Choice A) or vaccination. Choice B describes herd immunity, Choice C is passive immunity (e.g., immunoglobulin therapy), and Choice D, while a type of active immunity, is less general as it specifies recovery, whereas Choice A encompasses both infection and vaccination broadly.
