Final answer:
The assessment method with the highest sensitivity in detecting Small for Gestational Age (SGA) infants is the customized Estimated Fetal Weight (EFW) chart.
Step-by-step explanation:
When attempting to detect Small for Gestational Age (SGA) infants, there are several assessment methods that can be utilized. However, the method that demonstrates the highest sensitivity for this purpose is the customized Estimated Fetal Weight (EFW) chart. SFH, or symphysis-fundal height, is a traditional measure, but when it is customized for the mother's individual characteristics, it can provide more accurate assessment. Palpation alone is the least sensitive. Customization of these charts and measures allows for a more accurate reflection of expected fetal size based on individual maternal and fetal characteristics.
