Inpatient Obstetric Nurse (NCC) Practice Exam

Gestational Trophoblastic Disease (GTD) is characterized by the abnormal proliferation of trophoblastic tissue, which can lead to conditions such as hydatidiform mole and choriocarcinoma. In GTD, the trophoblastic tissue, which normally forms the placenta, overtakes the normal pregnancy tissue, leading to an abnormal growth pattern. This uncontrolled growth can result in a range of complications, including excessive hCG production and the potential for metastasis in more severe cases, such as in gestational choriocarcinoma. The other options refer to normal processes or characteristics that are not representative of GTD. Normal trophoblastic development relates to the healthy formation of placental tissue during a viable pregnancy, which is contrary to what occurs in GTD. Increased viability of pregnancy does not apply, as GTD is associated with complications and often results in the loss of pregnancy. Lastly, decidual tissue transformation is a typical response in a normal pregnancy but does not occur in the context of GTD, where the typical structures and functions of the placenta are disrupted.
