A nurse is admitting a client who has a diagnosis of preterm labor. The nurse anticipates an order by the provider for which of the following medications?

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: A tearful client who is at 32 weeks of gestation and is experiencing irregular, frequent contractions does not need to be reported to the provider immediately, because it may indicate preterm labor, which is not an emergency. The nurse should assess the client's cervix, fetal heart rate, and hydration status, and administer tocolytic therapy as prescribed.

Choice B reason: A client who has a diagnosis of preeclampsia has 2+ proteinuria and 2+ patellar reflexes does not need to be reported to the provider immediately, because they are expected findings in mild preeclampsia. The nurse should monitor the client's blood pressure, urine output, and reflexes, and administer antihypertensive and anticonvulsant medications as prescribed.

Choice C reason: A client who has a diagnosis of preeclampsia reports epigastric pain and unresolved headache needs to be reported to the provider immediately, because they are signs of severe preeclampsia or impending eclampsia. The nurse should prepare the client for delivery, as it is the only definitive treatment for preeclampsia.

Choice D reason: A client who is at 28 weeks of gestation and receiving terbutaline reports fine tremors does not need to be reported to the provider immediately, because they are a common and mild side effect of terbutaline, a beta-adrenergic agonist that relaxes the uterine smooth muscle. The nurse should reassure the client that the tremors are temporary and harmless, and monitor the client's pulse and blood pressure.
