A nurse is assessing the fontanels of an 8-month-old infant. Which of the following findings should the nurse recognize as an expected finding?

A. Both fontanels are the same size: Fontanels differ in size and shape; the anterior is larger and diamond-shaped, while the posterior is smaller and triangular. Expecting them to be the same size is inaccurate. B. The anterior fontanel is open: The anterior fontanel typically remains open until about 12–18 months of age. At 8 months, an open anterior fontanel is an expected finding and indicates normal skull development. C. The posterior fontanel is open: The posterior fontanel usually closes by 6–8 weeks of age. An open posterior fontanel at 8 months may indicate delayed closure and should be evaluated further. D. Both fontanels show molding: Molding refers to overlapping of cranial bones during birth. At 8 months, molding should no longer be present; its presence is not a normal finding at this age.
