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?

The correct answer is 200 mL/hr.

To calculate the IV rate, the nurse should use the following formula:

IV rate (mL/hr) = (Volume to be infused (mL) / Time of infusion (hr)) x Drop factor (gtt/mL)

In this case, the volume to be infused is 100 mL, the time of infusion is 0.5 hr (30 min), and the drop factor is 1 gtt/mL (assuming the IV pump is calibrated in mL/hr). Therefore, the formula becomes:

IV rate (mL/hr) = (100 mL / 0.5 hr) x 1 gtt/mL

IV rate (mL/hr) = 200 mL/hr

The nurse should round the answer to the nearest whole number, which is 200 mL/hr. The nurse should use a leading zero if the answer is less than 1, which is not the case here. The nurse should not use a trailing zero, which means 200 mL/hr and not 200.0 mL/hr.

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.
