A nurse in a prenatal clinic is teaching a client who is in her second trimester and has a new diagnosis of gestational diabetes. Which of the following statements by the client indicates a need for further teaching?

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.

Choice A reason: Irregular fetal heart rate is not an expected finding in a client with a hydatidiform mole, as it can indicate fetal arrhythmia, distress, or demise. A client with a hydatidiform mole may have no fetal heart tones, as the pregnancy is nonviable and consists of abnormal trophoblastic tissue.

Choice B reason: Rapid decline in human chorionic gonadotropin (hCG) levels is not an expected finding in a client with a hydatidiform mole, as it can indicate a normal or abnormal termination of pregnancy. A client with a hydatidiform mole may have markedly elevated hCG levels, as the trophoblastic tissue secretes excessive amounts of the hormone.

Choice C reason: Profuse, clear vaginal discharge is not an expected finding in a client with a hydatidiform mole, as it can indicate a normal or abnormal cervical mucus production. A client with a hydatidiform mole may have vaginal bleeding, which is often dark brown or bright red, and may contain grape-like vesicles.

Choice D reason: Excessive uterine enlargement is an expected finding in a client with a hydatidiform mole, as it reflects the rapid growth of the trophoblastic tissue and the accumulation of fluid-filled vesicles. A client with a hydatidiform mole may have a uterus that is larger than expected for the gestational age, and may experience uterine cramping or pain.
