The nurse is preparing a presentation for a health fair illustrating the major milestones of infants as they grow and develop. Which fact should the nurse point out when illustrating an infant’s teeth?
Fluoride should not be used on a child’s teeth before 4 or 5 years of age.
Swollen or inflamed gums during teething indicate a serious concern.
The first tooth usually erupts by 6 months.
The upper incisors are most often the first teeth to erupt.
The Correct Answer is C
Choice A reason: Fluoride is safe from 6 months in appropriate amounts, not delayed until 4-5 years. The first tooth’s eruption at 6 months is a key milestone, making this incorrect, as it misstates fluoride use in the context of infant dental development for the health fair.
Choice B reason: Swollen or inflamed gums are normal during teething, not a serious concern. The first tooth erupting at 6 months is a standard milestone, making this incorrect, as it misrepresents a common teething symptom as problematic in the nurse’s health fair presentation.
Choice C reason: The first tooth typically erupts by 6 months, marking the start of dental growth, a significant infant milestone. This aligns with pediatric dental guidelines, making it the correct fact for the nurse to highlight in the health fair presentation on infant developmental milestones.
Choice D reason: Lower central incisors, not upper, are usually the first to erupt in infants. The 6-month eruption timeline is accurate, making this incorrect, as it misidentifies the typical first teeth in the nurse’s presentation on infant dental development milestones at the health fair.

Correct Answer is B
Explanation
Choice A reason: Frequent bladder urges relate to bladder size and neurological maturation, not kidney location. Children’s higher kidney position increases trauma risk, making this unrelated and incorrect for the anatomical difference in kidney placement between children and adults in the context of injury risk.
Choice B reason: Children’s kidneys are proportionally larger and higher (near T12-L3) with less protective fat, increasing trauma risk from blunt injury. This anatomical difference aligns with pediatric urology evidence, making it the correct fact related to kidney location in children compared to adults.
Choice C reason: Fluid retention is a physiological process, not directly tied to kidney location. Children’s higher kidney placement increases trauma susceptibility, making this irrelevant and incorrect for the anatomical comparison of kidney position between children and adults in terms of health risks.
Choice D reason: Adults may have less fat, but children’s kidneys are less protected due to higher positioning and thinner fat layers. Trauma risk is the primary concern, making this partially correct but incorrect compared to the direct consequence of kidney trauma in children due to location.
Correct Answer is A
Explanation
Choice A reason: At birth, the infant’s right and left ventricles are nearly equal in size due to fetal circulation demands. This aligns with pediatric cardiology, making it the correct statement demonstrating understanding of the newborn’s cardiovascular system as discussed in the nurses’ review session.
Choice B reason: The heart matures earlier, with adult-like function by early childhood, not 8-10 years. Equal ventricle size at birth is accurate, making this incorrect, as it overestimates the timeline for cardiovascular maturation in the nurse’s understanding of the child’s heart development.
Choice C reason: Heart rate typically increases with fever in children, not decreases, due to metabolic demands. Equal ventricle size at birth is correct, making this inaccurate and incorrect compared to the true statement about the infant’s cardiovascular system in the nurses’ review.
Choice D reason: The left ventricle grows slightly larger but not twice the right’s size by 5-6 years. Equal ventricles at birth is accurate, making this incorrect, as it exaggerates ventricular growth in the nurse’s understanding of the child’s cardiovascular system development.
