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. The anterior fontanel typically remains open until about 12 to 18 months of age, sometimes even up to 24 months. Therefore, in an 8-month-old infant, it is expected and normal for the anterior fontanel to still be open, soft, and flat. B. The posterior fontanel normally closes much earlier, usually by 6 to 8 weeks of age (around 2 months). At 8 months, it should already be closed. If it remains open, it may indicate conditions such as hypothyroidism or increased intracranial pressure, and would require further evaluation. C. The anterior fontanel is significantly larger than the posterior fontanel. The posterior fontanel is small and triangular, while the anterior fontanel is larger and diamond-shaped. Therefore, they are not expected to be the same size at any age. D. Molding refers to the temporary shaping of the infant’s head during vaginal delivery due to overlapping of skull bones. This condition typically resolves within a few days after birth. At 8 months, molding should no longer be present, so this would be an abnormal finding.
