The following complications during pregnancy increase the risk of postpartum hemorrhage (PPH) except:
**Core Concept**
Pregnancy complications that increase the risk of postpartum hemorrhage (PPH) involve conditions that disrupt normal uterine contraction and hemostasis. These conditions often result from placental abnormalities, uterine atony, or coagulopathy.
**Why the Correct Answer is Right**
Uterine atony, multiple gestations, and placenta previa are well-established risk factors for PPH. Uterine atony occurs when the uterus fails to contract effectively after delivery, leading to excessive bleeding. Multiple gestations increase the risk of PPH due to the increased size of the uterus and the potential for uterine atony. Placenta previa is a condition where the placenta partially or completely covers the internal cervical os, increasing the risk of bleeding during delivery.
**Why Each Wrong Option is Incorrect**
* **Option A:** Uterine inversion is actually a risk factor for PPH. It occurs when the uterus turns inside out, disrupting normal uterine contraction and hemostasis. Uterine inversion can lead to severe bleeding and is a medical emergency.
* **Option B:** Polyhydramnios, or excessive amniotic fluid, is not typically associated with an increased risk of PPH. In fact, polyhydramnios may be more commonly linked to an increased risk of uterine rupture.
* **Option C:** **This option is not provided.**
* **Option D:** **This option is not provided.**
**Clinical Pearl / High-Yield Fact**
It's essential to note that the risk of PPH is higher in women with a history of previous PPH, uterine surgery, or multiple gestations. Clinicians should take a thorough history and perform a thorough examination to identify women at high risk for PPH.
**Correct Answer:** A. Uterine inversion is actually a risk factor for PPH.
