2024 PN NCLEX Questions Nursing Practice Question
An assessment of the skull of a normal 10-month-old baby should identify which of the following?
Correct Answer: A
Rationale: At 10 months, the posterior fontanel typically closes between 2 to 3 months of age, making its closure expected by this age.
Option B is incorrect; the anterior fontanel usually remains open until 12 to 18 months, so it should not be closed in a 10-month-old.
Option C is misleading; while some overlap of cranial bones can occur, it is not a definitive finding at this age.
Option D is also inaccurate; while sutures begin to ossify, complete ossification does not occur until later in childhood. Thus, the closure of the posterior fontanel is the most appropriate finding for a 10-month-old.
