Question

A nurse understands that an average weight for a 12-month-old is:

1) 18.5 pounds
2) 21.5 pounds
3) 28.5 pounds
4) 34.5 pounds

Answer 1

A nurse understands that an average weight for a 12-month-old is: 3) 28.5 pounds

Step-by-step explanation:

The weight of a newborn usually doubles in six months and triples in one year. By 2 years old, the weight will have quadrupled. During the first week following birth, it is normal for the weight of a newborn to decrease due to fluid resorption and urination. However, after the first week, a healthy newborn should start to gain up to 20 grams per day.

Overall, a well-nourished, full-term newborn has an average birth weight of 3.4 kg (7.5 lb), and by 12 months, they should have tripled their birth weight. Therefore the correct answer is 3) 28.5 pounds
