What should you do to assist in a delivery?

Supporting and guiding the baby's head during delivery is critical for several reasons. This action helps ensure a safe and controlled birth, minimizing the risk of trauma to both the baby and the mother. By providing gentle support, you assist the baby in making its way through the birth canal, allowing for a smoother delivery process. Supporting the head also helps to prevent complications such as shoulder dystocia, where the shoulders become stuck during birth.

In the context of a delivery, focusing exclusively on the mother's vital signs or recording diet history would not be immediately relevant or beneficial. These actions do not actively assist in the process of delivery and could divert attention away from the urgent needs of both the mother and the newborn. Extracting the baby forcibly is also dangerous and can cause serious harm to both the baby and the mother. Therefore, guiding and supporting the baby's head is a vital intervention during childbirth that can lead to better outcomes.
