Question

How are Small for Gestational Age (SGA) infants identified based on weight, head circumference, and length percentiles?

A) All measurements below the 5th percentile.

B) Weight, head circumference, and length all below the 10th percentile.

C) Weight below the 10th percentile, regardless of head circumference and length.

D) Head circumference below the 10th percentile, regardless of weight and length.

Answer 1

SGA infants are typically identified by weight below the 10th percentile, without regard to head circumference and length, which makes option C the correct answer.

Step-by-step explanation:

Small for Gestational Age (SGA) infants are identified by specific measurements that are compared to standard percentiles. These infants typically have birth weights that are significantly less than the average for their gestational age. A key indicator is having a weight below the 10th percentile, regardless of their head circumference and length, answering the student's question with option C. Full-term infants usually weigh around 3.4 kg (7.5 lb), and those with a birth weight under 2.5 kg (5.5 lb) are considered low birth weight, which is a contributing factor to the SGA classification. Moreover, regular doctor visits to monitor the baby's development in the first year are crucial for assessing their growth and identifying any potential issues with undernutrition or slow growth.
