The goal of applying suprapubic pressure during delivery is to aid in the expulsion of the baby from the uterus.
Step-by-step explanation:
The goal of applying suprapubic pressure during Ms. Song's delivery was to assist in the expulsion of the baby from the uterus during stage two of labor. Suprapubic pressure is applied by pressing down on the area just above the pubic bone. This action helps to guide and direct the baby through the birth canal, aiding in the delivery process.
