## Core Concept
The active management of the third stage of labor (AMTSL) is a crucial obstetric intervention aimed at reducing postpartum hemorrhage (PPH) and promoting uterine involution. It involves a series of evidence-based steps to ensure the safe delivery of the placenta and minimize blood loss.

## Why the Correct Answer is Right
Active management of the third stage of labor includes three main components:
1. Administration of a uterotonic agent (usually oxytocin) to stimulate uterine contractions.
2. Controlled cord traction (CCT) applied to the umbilical cord to help deliver the placenta.
3. Uterine massage after delivery of the placenta if necessary.

## Why Each Wrong Option is Incorrect
- **Option A:** Administering a uterotonic agent is a fundamental part of AMTSL, helping to reduce the risk of PPH by inducing uterine contractions.
- **Option B:** Controlled cord traction is another essential component, aiding in the delivery of the placenta and reducing the risk of retained placental tissue.
- **Option D:** Uterine massage after placental delivery may be performed if the uterus is not well contracted, making it a part of AMTSL.

## Clinical Pearl / High-Yield Fact
A key point to remember is that AMTSL significantly reduces the risk of postpartum hemorrhage, which is a leading cause of maternal morbidity and mortality worldwide. Early recognition and management of PPH are critical.

## Correct Answer: D.
