A woman in her second trimester of pregnancy is diagnosed with preeclampsia. Which of the following statements about preeclampsia will guide the care provided to this patient?

Preeclampsia is a multi-system, vasospastic disease. A vasospastic disorder results in intermittent or impaired arterial circulation in the body. Vasospasm in the placenta causes impaired placental perfusion. Impaired perfusion results in decreased delivery of oxygen and nutrients to the fetus by the placenta, restricting fetal growth.
