A nurse is assessing a 12-month-old infant who is brought to the clinic by the parents for a well-child visit. The nurse reviews the infant's health history and notes that the infant weighed 8 lb at birth. When assessing the infant's weight at this visit, the nurse would anticipate that the infant would weigh approximately how much at this time?

Answer and Explanation

The Correct Answer is C

A. 20 lbs: This is a plausible estimate. By 12 months, an infant's birth weight typically triples. Therefore, an 8 lb birth weight would approximately translate to 24 lbs at 12 months.

B. 32 lbs: This estimate is too high. If an infant's birth weight triples by 12 months, an 8 lb birth weight would not be expected to reach 32 lbs.

C. 24 lbs: An infant's weight usually triples by their first birthday. Therefore, an infant born weighing 8 lbs would be expected to weigh about 24 lbs at 12 months.

D. 16 lbs: This is an underestimate. An 8 lb infant would double their birth weight by about 4 to 6 months, and by 12 months, they would typically have tripled their birth weight to around 24 lbs.
