Final answer:
A Large for Gestational Age (LGA) infant is characterized as having birth weight, head circumference, and length measurements above the 90th percentile.
Step-by-step explanation:
The percentile range that characterizes a Large for Gestational Age (LGA) infant based on birth weight, head circumference, and length is above the 90th percentile. Infants that are classified as LGA are larger than the majority of their peers for their gestational age, which could lead to certain health risks both at birth and later in life. Babies born with a weight, head circumference, or length above the 90th percentile indicates that they are in the highest ten percent of babies of the same gestational age, which is indicative of being LGA.
