The nurse knows that the school-age child is in Erikson's stage of industry versus inferiority. Which best exemplifies a school-ager working toward accomplishing this developmental task?

A. The use of car seats and other safety measures is crucial for the child's safety and is a standard part of a functional history to ensure that the child is being protected from common household and travel-related injuries.

B. The use of supplements and vitamins can significantly impact a child's health, especially at a developmental age, and should be monitored and recorded.

C. Prenatal and perinatal histories are typically reviewed during initial visits and not necessarily part of a routine functional history for a 2-year-old unless there are ongoing health issues related to birth.

D. The child's race and ethnicity are important for demographic data but are not typically part of a functional history unless there are specific cultural practices or genetic predispositions that affect the child's health.

E. The child's toileting habits are an important aspect of their development and daily functioning, and changes or issues in this area can indicate health concerns.

A. Areola and papilla separate from the contour of the breast: This is a normal finding in breast development and indicates Tanner stage 4 or higher, which is typical for adolescent girls. It does not necessarily indicate a developmental delay.

B. Absence of first menstrual perioD. Menarche, the first menstrual period, typically occurs between the ages of 9 and 15 in girls. Absence of menarche by the age of 15 or within 3 years after the onset of breast development (thelarche) may indicate a developmental delay or underlying medical condition that should be evaluated by a healthcare provider.

C. Developed breast tissuE. Breast development, indicated by palpable breast tissue, is a normal part of female puberty and typically occurs before menarche. Developed breast tissue alone does not necessarily indicate a developmental delay.

D. Mature distribution and coarseness of pubic hair: Pubic hair development is also a part of female puberty and occurs before or around the time of menarche. While the distribution and coarseness of pubic hair can provide information about pubertal development, the absence of menarche is a more reliable indicator of a potential developmental delay.
