Which of the following symptoms is associated with uterine rupture?

Uterine rupture can lead to serious complications during pregnancy, including significant internal bleeding. The correct answer involves thirst and dizziness, which can be indicative of hypovolemic shock. When a rupture occurs, blood vessels may tear, causing bleeding into the abdominal cavity or uterus. As blood volume decreases, the body compensates by activating mechanisms that can lead to these symptoms. Thirst is a response to dehydration, while dizziness can signify a decrease in blood pressure and perfusion as a result of significant blood loss.

In contrast, increased fetal movement is not typically associated with uterine rupture; rather, it may be a sign of fetal well-being or response to maternal activity. Nausea might be related to various conditions in pregnancy but is not a direct indicator of uterine rupture. Headaches could indicate many different issues, such as tension or preeclampsia, but they do not specifically point to uterine rupture like thirst and dizziness do. Understanding these symptoms helps in identifying the severity of the situation and the necessary medical response.
