A primigravida at 40 weeks of gestation is having uterine contractions every 1.5 to 2 minutes and states that they are very painful. Her cervix is dilated 2 cm and has not changed in 3 hours. The woman is crying and wants an epidural. What is the likely status of this woman's labor?

Choice A reason: This statement is incorrect, as it is not the definition of polyhydramnios, but rather a possible cause of it. Polyhydramnios is a condition where the amniotic fluid volume exceeds 2,000 mL at term, or the amniotic fluid index (AFI) is greater than 25 cm. Polyhydramnios can occur in multiple pregnancies, as the fetuses produce more urine and fluid than a single fetus.

Choice B reason: This statement is incorrect, as it is not the definition of polyhydramnios, but rather a possible complication of it. Polyhydramnios can cause fetal anomalies, such as esophageal atresia, anencephaly, or neural tube defects, which impair the swallowing or absorption of the amniotic fluid. Polyhydramnios can also cause fetal growth restriction or distress, as the excess fluid can compress the umbilical cord or the placenta, and reduce the blood flow and oxygen delivery to the fetus.

Choice C reason: This statement is correct, as it is the definition of polyhydramnios, which is a condition where the amniotic fluid volume exceeds 2,000 mL at term, or the amniotic fluid index (AFI) is greater than 25 cm. Polyhydramnios can be diagnosed by ultrasound, and it can cause maternal and fetal complications, such as preterm labor, premature rupture of membranes, placental abruption, or cord prolapse.

Choice D reason: This statement is incorrect, as it is not the definition of polyhydramnios, but rather a marker of fetal anomalies. Alpha-fetoprotein (AFP) is a protein that is produced by the fetus, and it can be measured in the maternal serum or the amniotic fluid. An elevated level of AFP in the amniotic fluid can indicate fetal anomalies, such as neural tube defects, abdominal wall defects, or renal anomalies, which can cause polyhydramnios.

Choice A reason: Preeclampsia is not the correct answer, as it is a hypertensive disorder of pregnancy that causes high blood pressure, proteinuria, and edema. Preeclampsia can be a risk factor for abruptio placentae, which is a premature separation of the placenta from the uterine wall, but it is not a complication of it. Preeclampsia does not cause petechiae or bleeding around the IV access site, but rather headaches, blurred vision, or epigastric pain.

Choice B reason: Anaphylactoid syndrome of pregnancy is not the correct answer, as it is a rare and fatal condition that occurs when the amniotic fluid enters the maternal circulation and causes an allergic reaction. Anaphylactoid syndrome of pregnancy can occur as a complication of abruptio placentae, but it is not indicated by the petechiae or bleeding around the IV access site. Anaphylactoid syndrome of pregnancy would cause respiratory distress, hypotension, or cardiac arrest.

Choice C reason: Puerperal infection is not the correct answer, as it is a bacterial infection of the reproductive tract that occurs after childbirth. Puerperal infection can occur as a complication of abruptio placentae, but it is not indicated by the petechiae or bleeding around the IV access site. Puerperal infection would cause fever, foul-smelling lochia, or pelvic pain.

Choice D reason: Disseminated intravascular coagulation is the correct answer, as it is a coagulation disorder that causes widespread clotting and bleeding in the body. Disseminated intravascular coagulation can occur as a complication of abruptio placentae, and it is indicated by the petechiae and bleeding around the IV access site. Disseminated intravascular coagulation would also cause a low platelet count, a prolonged prothrombin time (PT) and activated partial thromboplastin time (aPTT), and a low fibrinogen level.
