Which of the following could be a serious concern immediately after delivery?

Immediately after delivery, excessive bleeding, known as postpartum hemorrhage, is a serious concern. This condition can occur if the uterus does not contract effectively after childbirth, leading to significant blood loss. Monitoring for signs of excessive bleeding is crucial in the immediate postpartum period, as it can result in shock and even be life-threatening if not addressed promptly.

In contrast, while jaundice, low birth weight, and infection are important health considerations, they typically do not present as immediate concerns right after childbirth. Jaundice may develop a few days after birth as bilirubin accumulates, low birth weight is assessed at the time of delivery but is not an immediate emergency, and while infections can develop postpartum, they are not immediate threats experienced right after the delivery process itself. Thus, the priority during the immediate postpartum period is to manage potential excessive bleeding effectively.
