Pediatric Immunity NCLEX Questions Questions
Question 1 of 5
According to Piaget’s theories of cognitive development, a 29-month-old boy who crawls under the couch to retrieve a ball demonstrates:
Correct Answer: A
Rationale: Object permanence (sensorimotor stage, 0–2 years) is understanding objects exist when out of sight, shown by retrieving the ball. Basic trust (B) is Erikson’s. Object constancy (C) is unrelated. Sensorimotor (D) is the stage, not the behavior.
Question 2 of 5
Treatment of sickle cell anemia is aimed at maintaining blood flow to the smaller vessels and diminishing the amount of excess blood cells being made by the bone marrow.
Correct Answer: A
Rationale: Sickle cell treatment focuses on hydration and oxygenation to maintain blood flow and prevent vaso-occlusion. Hydroxyurea reduces excess sickle cell production by the marrow, supporting Option A as true.
Question 3 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 4 of 5
A 14-year-old girl... polycystic ovarian syndrome... hirsutism, amenorrhea, and virilization... These findings are most likely due to which of the following agents?
Correct Answer: D
Rationale: PCOS involves elevated androgens (testosterone), causing hirsutism, amenorrhea, and virilization. Estrogen (A) opposes these. FSH (B) and LH (C) are dysregulated but not the direct cause.
Question 5 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.
