True or false: The number one cause of postpartum hemorrhage is uterine atony.

• A. True
• B. False
• C. Only in cases of cesarean deliveries
• D. Only if there are previous deliveries

Answer: (A)

The statement that the number one cause of postpartum hemorrhage is uterine atony is true. Uterine atony refers to the lack of muscle tone in the uterus, which can occur after delivery when the uterine muscles fail to contract adequately. This failure to contract can lead to excessive bleeding, as the uterine contractions are essential for compressing the blood vessels that supply the placental site.

This condition accounts for a significant percentage of postpartum hemorrhage cases, making it a critical concern in maternity care. Understanding the role of uterine atony is vital for healthcare providers, as timely interventions can significantly reduce the risks associated with postpartum hemorrhage. Therefore, robust knowledge about uterine atony and its management is essential for ensuring patient safety and improving maternal outcomes.
