a.1 month
b.6 to 9 months
c.1 to 2 years
d.to 3 years

Answer 1

The nurse's interpretation of a larger head circumference than chest circumference in a 10-month-old as normal is correct, as the head and chest circumference usually become equal at 1 to 2 years of age. The Correct Answer is Option C.

Step-by-step explanation:

The nurse's observation that a 10-month-old infant has a larger head circumference than chest circumference is interpreted as a normal finding because the head and chest circumference become equal at approximately 1 to 2 years of age.

In the early stages of development, an infant's head grows more proportionally compared to the rest of the body to accommodate rapid brain growth. By the end of the first year, an infant typically triples their birth weight and experiences significant growth in head and trunk size, essential for the development of the brain, heart, and lungs.
