The Mother of a 9-Month-Old Infant Is Concerned That the Head

The mother of a 9-month-old infant is concerned that the head circumference of her baby is greater than the chest circumference. The best response by the nurse is:

A) "This is normal until the age of 1 year, and then the chest will be greater."
B) "Perhaps your baby was small for gestational age or premature."
C) "Let me ask you a few questions, and perhaps we can figure out the cause of this difference."
D) "These circumferences normally are the same, but in some babies this just differs."
