Answer to Question 1

ANS: C
Growth is very rapid during the first year of life. The birth weight approximately doubles by age 5 to 6 months and triples by age 1 year. The anterior fontanel closes at age 12 to 18 months. Binocularity is not established until age 15 months. Maternal iron stores are usually depleted by age 6 months.

Answer to Question 2

ANS: A
Because the anterior fontanel normally closes between ages 12 and 18 months, this is a normal finding, and no further intervention is required.
