A nurse is collecting data from a 6-month-old infant in the well-child clinic.
Which of the following findings should the nurse expect?
Lateral incisors are present.
Posterior fontanel is closed.
Infant's birth weight is tripled.
Infant sits well without support.
The Correct Answer is B
A. Lateral incisors are present: At 6 months, infants typically begin teething, but the lateral incisors usually do not appear until around 9 to 13 months. The first teeth to emerge are usually the lower central incisors.
B. Posterior fontanel is closed: The posterior fontanel, or the soft spot at the back of the baby's head, typically closes by 2 to 3 months of age. Therefore, it is expected to be closed by the time the infant is 6 months old.
C. Infant's birth weight is tripled: By 6 months, infants generally double their birth weight. Tripling of birth weight is more commonly expected by the end of the first year.
D. Infant sits well without support: Most infants begin to sit without support around 7 to 9 months. At 6 months, they may sit with some support but are not yet expected to sit well independently.
