A primigravida is being monitored at the prenatal clinic for preeclampsia. Which finding is of greatest concern to the nurse?

Choice A reason: Placing the newborn in Trendelenburg position is not an appropriate nursing action, as it can cause increased intracranial pressure, decreased lung expansion, and aspiration. The nurse should position the newborn in a neutral or slightly elevated head position, with the neck slightly extended.

Choice B reason: Maintaining oxygen saturations between 93% to 95% is an appropriate nursing action, as it ensures adequate oxygen delivery to the tissues and organs, while avoiding hyperoxia or hypoxia, which can cause complications, such as retinopathy of prematurity, intraventricular hemorrhage, or necrotizing enterocolitis.

Choice C reason: Inserting an orogastric tube for decompression of the stomach is not an appropriate nursing action, as it is not indicated for oxygen hood therapy, unless the newborn has abdominal distension, vomiting, or feeding intolerance. The nurse should monitor the newborn's abdominal girth, bowel sounds, and feeding tolerance, and report any signs of gastrointestinal dysfunction.

Choice D reason: Removing the hood every hour for 10 min to facilitate bonding is not an appropriate nursing action, as it can cause fluctuations in the oxygen concentration and temperature, and increase the risk of infection. The nurse should maintain the hood in place, and encourage the parents to touch, talk, and sing to the newborn, and provide skin-to-skin contact when possible.

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.
