**Core Concept**
Postpartum hemorrhage (PPH) is a leading cause of maternal mortality worldwide. Effective management of PPH involves the use of uterotonic agents that help to reduce uterine tone and prevent excessive bleeding.

**Why the Correct Answer is Right**
The primary goal of treating PPH is to control bleeding and restore uterine tone.
