Emergency aid for childbirth implies that the first responder must support the baby's head and not pull on the baby. What other actions should they take?

The requirement for a first responder during childbirth to assist the upper shoulder and support the body is crucial for ensuring both the mother and baby have a safe delivery. The first responder's focus should be on providing appropriate support to the baby as it emerges, which includes assisting the upper shoulder through the birth canal while maintaining proper body alignment. Supporting the baby's body as well as being mindful of the position of the head can help prevent injury to both the infant and the mother.

Merely encouraging the baby to breathe or focusing solely on clearing the airway, while important aspects of newborn care, do not address the immediate needs of the birthing process and may lead to complications if the infant is not properly assisted during delivery. Therefore, the most effective response in this situation emphasizes hands-on support during the delivery process itself, making option B the most suitable choice.
