A client comes to the emergency room reporting severe abdominal cramping and heavy bleeding at 10 weeks gestation. Cervical examination reveals heavy bleeding, the cervical os is open and tissue is present. Which type of abortion is the client experiencing?

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: Molar pregnancy is a risk factor for hyperemesis gravidarum, as it is a gestational trophoblastic disease that causes an abnormal growth of the placenta and the production of high levels of human chorionic gonadotropin (hCG), which is a hormone that stimulates nausea and vomiting. Molar pregnancy can cause severe and persistent hyperemesis gravidarum, as well as vaginal bleeding, uterine enlargement, and preeclampsia.

Choice B reason: Previous history of hyperemesis gravidarum is a risk factor for hyperemesis gravidarum, as it suggests a genetic or physiological predisposition to the condition. Hyperemesis gravidarum is a severe form of nausea and vomiting that occurs in pregnancy, and it can cause dehydration, electrolyte imbalance, weight loss, and malnutrition. Hyperemesis gravidarum can recur in subsequent pregnancies, especially if the mother has the same partner, the same sex of the fetus, or a short interval between pregnancies.

Choice C reason: Oligohydramnios is not a risk factor for hyperemesis gravidarum, as it is a low level of amniotic fluid that surrounds the fetus. Oligohydramnios is not related to hyperemesis gravidarum, and it is not a cause or a consequence of it. Oligohydramnios can affect the fetal development and the delivery, as it can cause fetal growth restriction, cord compression, or meconium aspiration.

Choice D reason: Multiple fetal gestation is a risk factor for hyperemesis gravidarum, as it is a condition where the mother is carrying more than one fetus. Multiple fetal gestation can cause higher levels of hCG, estrogen, and progesterone, which are hormones that stimulate nausea and vomiting. Multiple fetal gestation can cause more severe and prolonged hyperemesis gravidarum, as well as preterm labor, anemia, and preeclampsia.
