Final answer:
The nurse would expect a 12-month-old child to have tripled their birth weight, as infants typically reach this milestone by their first birthday.
Step-by-step explanation:
The nurse evaluating the growth of a 12 month-old child would expect to find that the child has tripled the birth weight. This expectation is due to the fact that on average, a healthy and well-nourished infant, after the initial weight loss immediately post-birth, gains weight rapidly and usually doubles the birth weight by six months and triples it by the first birthday. Concerning other options, having more than two deciduous teeth would be more typical by 12 months, and head circumference tending to be greater than chest circumference until about 1 to 2 years of age, before the chest circumference surpasses the head circumference.
