Which nursing action is essential for preventing postpartum hemorrhage related to uterine atony?

Massaging the uterus is a crucial nursing action for preventing postpartum hemorrhage related to uterine atony because it stimulates uterine contractions, which help the uterus to firm up and reduce blood loss. Uterine atony, a condition where the uterus fails to contract adequately after childbirth, can lead to significant postpartum hemorrhage. By performing fundal massage, the nurse promotes the contraction of the uterine muscles, which is vital in controlling and preventing excessive bleeding.

While administering medications, encouraging ambulation, and monitoring vital signs are important components of overall postpartum care, they do not specifically address the immediate need to promote uterine contraction in cases of uterine atony. Effective fundal massage directly mitigates the risk of hemorrhage by ensuring that the uterus maintains normal tone and actively engages in the recovery process after delivery. Thus, it is the most critical intervention in this scenario.
