A nurse is collecting data from a 4-month-old infant at a well-child visit. For which of the following findings should the nurse notify the provider?
Correct answer
A
Rationale
The correct answer is A because the anterior fontanel normally closes around 12-18 months. Premature closure could indicate dehydration or craniosynostosis. Choices B, D are appropriate developmental milestones for a 4-month-old. Choice C, the posterior fontanel closes around 2-3 months, so it being closed is normal.
