Final answer:
An Appropriate Gestational Age (AGA) infant would have measurements falling within the 10th to 90th percentile. This indicates that the infant's weight and length are within the normal range for their gestational age.
Step-by-step explanation:
An Appropriate for Gestational Age (AGA) infant is typically characterized by birth weight, head circumference, and length that fall within the 10th to 90th percentile. More specifically, these percentiles refer to standard growth charts and indicate that the baby's measurements are within the normal range for their gestational age.
Babies that fall below the 10th percentile or above the 90th percentile are considered Small for Gestational Age (SGA) or Large for Gestational Age (LGA), respectively. Infants within the AGA range are expected to have a birth weight that normally ranges from 2.5 to 4.5 kg (5.5 to 10 lb) if they are full-term. Additionally, the total body length of a full-term AGA infant at birth typically ranges between 46 and 56 cm (18 and 22 inches), with an average of 51 cm (20 in.).
Therefore, the correct answer to the question 'What percentile range characterizes an Appropriate for Gestational Age (AGA) infant based on birth weight, head circumference, and length?' is B) Between the 10th and 90th percentiles.
