For a 6 month old infant who weighed 7 pounds at birth, what is the minimum expected weight for normal range?

1. 10 pounds

2. 14 pounds

3. 18 pounds

4. 21 pounds

The correct answer is: 14 pounds

For a 6-month-old infant who weighed 7 pounds at birth, the minimum expected weight for the normal range can be determined using established growth patterns in infants. It is commonly understood that infants typically double their birth weight by around 4 to 6 months of age. Since this infant weighed 7 pounds at birth, we would expect the infant to reach a weight of approximately 14 pounds by the age of 6 months. This figure corresponds to the general guideline that most infants will double their birth weight within this timeframe, aligning with the growth pattern observed in healthy, developing infants. Thus, the selection of 14 pounds as the minimum expected weight for a 6-month-old infant accurately reflects the standard developmental milestone. This growth is essential for assessing the overall health and nutrition status of the infant.
