The nurse is providing education to a teen mother about her 20-month-old daughter's growth. The teen says her daughter seems to have such a big head. What information should the nurse include in the response?

Choice A reason: While some children may have larger heads, this response lacks scientific explanation and may dismiss the parent's concern without providing reassurance or education. It is vague and not informative. Choice B reason: Telling the parent that the child "looks normal" is subjective and does not address developmental norms. It may be perceived as dismissive and does not offer educational value. Choice C reason: This is the most accurate and developmentally appropriate response. At 20 months, the head is proportionally larger compared to the rest of the body due to rapid brain growth in infancy. This normalizes over time as the body grows and proportions balance out. Choice D reason: While the head-to-body ratio does improve with age, stating that it will remain disproportionate until age 6 is misleading. Significant changes occur earlier, and the head becomes more proportionate by preschool age.
