The labor of a pregnant woman with preeclampsia is going to be induced. Before initiating the oxytocin (Pitocin) infusion, the nurse reviews the woman's latest laboratory test findings, which reveal a platelet count of 90,000 mm3, an elevated aspartate aminotransferase (AST) level, and a falling hematocrit. The laboratory results are indicative of which condition?

Choice A reason: Uterine enlargement greater than expected for gestational age is not a typical manifestation of ectopic pregnancy, because the embryo is implanted outside the uterus, usually in the fallopian tube. The uterus may be slightly enlarged due to hormonal changes, but not more than expected for the gestational age.

Choice B reason: Unilateral, cramp-like abdominal pain is a common manifestation of ectopic pregnancy, because the embryo grows and stretches the fallopian tube, causing inflammation and irritation. The pain may be mild or severe, depending on the size and location of the ectopic pregnancy, and may radiate to the shoulder or back.

Choice C reason: Severe nausea and vomiting is not a specific manifestation of ectopic pregnancy, because it can be caused by other conditions, such as hyperemesis gravidarum, gastroenteritis, or appendicitis. The client may have mild nausea and vomiting due to hormonal changes, but not more than usual for the gestational age.

Choice D reason: Large amount of vaginal bleeding is not a usual manifestation of ectopic pregnancy, because the bleeding is usually internal, into the abdominal cavity. The client may have spotting or light bleeding due to the detachment of the endometrium, but not heavy or profuse bleeding.

Choice A reason: Disseminated intravascular coagulation (DIC) syndrome is not the correct answer, as it is a coagulation disorder that causes widespread clotting and bleeding in the body. DIC can occur as a complication of severe preeclampsia, but it is not indicated by the laboratory results. DIC would cause a low platelet count, but also a prolonged prothrombin time (PT) and activated partial thromboplastin time (aPTT), and a low fibrinogen level.

Choice B reason: Eclampsia is not the correct answer, as it is a seizure disorder that occurs in clients with severe preeclampsia. Eclampsia can occur as a complication of severe preeclampsia, but it is not indicated by the laboratory results. Eclampsia would cause a high blood pressure, but also a proteinuria, edema, and hyperreflexia.

Choice C reason: Hemolysis, elevated liver enzyme levels, and low platelet levels (HELLP) syndrome is the correct answer, as it is a variant of severe preeclampsia that affects the blood and the liver. HELLP syndrome is indicated by the laboratory results, as it causes a low platelet count, an elevated AST level, and a falling hematocrit. HELLP syndrome would also cause a high blood pressure, a proteinuria, and a right upper quadrant pain.

Choice D reason: Idiopathic thrombocytopenia is not the correct answer, as it is an autoimmune disorder that causes the destruction of platelets by antibodies. Idiopathic thrombocytopenia can affect pregnant women, but it is not related to severe preeclampsia or the laboratory results. Idiopathic thrombocytopenia would cause a low platelet count, but not an elevated AST level or a falling hematocrit.
