What explanation should a preceptor provide about postpartum hemorrhage following shoulder dystocia?

When discussing postpartum hemorrhage in the context of shoulder dystocia, it's essential to understand the relationship between macrosomic infants, shoulder dystocia, and uterine atony. Infants with macrosomia, or increased birth weight, are at a higher risk for experiencing shoulder dystocia due to their larger shoulder circumference. This increased size can also influence the mother's uterine tone, making her more susceptible to uterine atony, which is a common cause of postpartum hemorrhage. When the uterus is unable to contract effectively, it can lead to excessive bleeding following delivery.

Therefore, the correct explanation points to the interconnected risks associated with macrosomic infants and the physiological responses during and after birth. Recognizing this relationship allows healthcare providers to better anticipate complications related to both shoulder dystocia and hemorrhaging, and to implement appropriate interventions to mitigate these risks.
