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 is open: This is an expected finding in an 8-month-old infant. The anterior fontanel typically remains open until around 12 to 18 months of age, allowing for brain growth. B) Both fontanels show molding: Molding is usually a temporary shape change of the skull that occurs during birth, particularly in relation to the birth canal. By 8 months, the fontanels should not show molding. C) Both fontanels are the same size: The anterior fontanel is generally larger than the posterior fontanel. The posterior fontanel typically closes by 2 to 3 months of age and is much smaller. D) The posterior fontanel is open: This finding is not expected, as the posterior fontanel should have closed by 2 to 3 months of age. An open posterior fontanel at 8 months could indicate a developmental concern.
