**Core Concept:** Postpartum bleeding, also known as postpartum hemorrhage (PPH), is a significant cause of maternal mortality worldwide. It is defined as heavy menstrual-like bleeding that occurs in the first 6 weeks after delivery, with a blood loss of more than 500 ml or leading to hemodynamic instability.

**Why the Correct Answer is Right:** In this scenario, the correct answer involves a prompt clinical assessment and management to prevent maternal morbidity and mortality due to PPH.

**Why Each Wrong Option is Incorrect:**

A. **Option A:** This option is incorrect because the patient's bleeding should be evaluated for underlying causes before initiating treatment.

B. **Option B:** While controlling bleeding with manual compression or digital pressure is important, it should be done in conjunction with other interventions, not as the sole solution.

C. **Option C:** Antibiotics are not the primary treatment for PPH. The focus should be on addressing the underlying cause and stopping the bleeding.

D. **Option D:** Administering uterotonics (such as oxytocin or prostaglandins) is essential in managing PPH, as it helps to contract the uterus and stop the bleeding.

**Clinical Pearl:** The correct management of PPH involves a combination of clinical assessment (vital signs, hemodynamic stability), identification of potential causes (placenta retention, uterine atony, coagulopathy, or lacerations), and implementing appropriate interventions. These include manual compression or digital pressure, uterotonics, and, if necessary, surgical consultation and/or intervention.

**Correct Answer:** D. Administer uterotonics (e.g., oxytocin or prostaglandins) to contract the uterus and stop the bleeding.
