Which of the following complications may arise from severe uterine bleeding during pregnancy?

Severe uterine bleeding during pregnancy can lead to hypovolemic shock, which is a critical condition resulting from a significant loss of blood volume. When the body experiences substantial blood loss, the cardiovascular system struggles to maintain adequate blood circulation, leading to decreased oxygen delivery to vital organs. This situation can cause symptoms such as rapid heart rate, low blood pressure, confusion, and even loss of consciousness if not promptly treated.

In the context of pregnancy, hypovolemic shock is particularly concerning because it can endanger both the mother’s life and the fetus's well-being. Timely intervention is essential to manage the bleeding and stabilize the mother's condition, protecting the developing baby from compromising situations, such as reduced blood flow and oxygen supply.

Fluid overload, oligohydramnios, and gestational diabetes, while they can occur in various pregnancy scenarios, are not direct complications resulting from severe uterine bleeding. Fluid overload typically arises from excessive intravenous fluid administration, oligohydramnios pertains to low amniotic fluid levels for reasons other than bleeding, and gestational diabetes is related to metabolic changes during pregnancy rather than associated with uterine bleeding.
