A nurse is admitting a client who is at 30 weeks of gestation and is in preterm labor. The client has a new order for betamethasone and asks the nurse about the purpose of this medication. The nurse should provide which of the following explanations?
"It promotes fetal lung maturity."
"It halts cervical dilation."
"It increases the fetal heart rate."
"It is used to stop preterm labor contractions."
The Correct Answer is A
Choice A reason: This statement is correct, as betamethasone is a corticosteroid that is given to pregnant women who are at risk of delivering before 34 weeks of gestation. Betamethasone stimulates the production of surfactant, which is a substance that prevents the alveoli from collapsing and improves the lung function of the fetus.
Choice B reason: This statement is incorrect, as betamethasone does not affect the cervical dilation, which is a sign of labor progression. Betamethasone does not stop or delay labor, but rather reduces the complications of prematurity, such as respiratory distress syndrome, intraventricular hemorrhage, or necrotizing enterocolitis.
Choice C reason: This statement is incorrect, as betamethasone does not increase the fetal heart rate, which is a measure of fetal well-being. Betamethasone may cause transient fetal bradycardia, which is a decrease in the fetal heart rate, due to the increased vagal tone and blood pressure. The nurse should monitor the fetal heart rate and notify the provider if there are any signs of fetal distress.
Choice D reason: This statement is incorrect, as betamethasone is not used to stop preterm labor contractions, which are caused by the uterine muscle activity. Betamethasone does not have any tocolytic effect, which is the ability to inhibit uterine contractions. Other medications, such as magnesium sulfate, nifedipine, or indomethacin, may be used to stop preterm labor contractions.

Correct Answer is D
Explanation
Choice A reason: Preeclampsia is not the correct answer, as it is a hypertensive disorder of pregnancy that causes high blood pressure, proteinuria, and edema. Preeclampsia can be a risk factor for abruptio placentae, which is a premature separation of the placenta from the uterine wall, but it is not a complication of it. Preeclampsia does not cause petechiae or bleeding around the IV access site, but rather headaches, blurred vision, or epigastric pain.
Choice B reason: Anaphylactoid syndrome of pregnancy is not the correct answer, as it is a rare and fatal condition that occurs when the amniotic fluid enters the maternal circulation and causes an allergic reaction. Anaphylactoid syndrome of pregnancy can occur as a complication of abruptio placentae, but it is not indicated by the petechiae or bleeding around the IV access site. Anaphylactoid syndrome of pregnancy would cause respiratory distress, hypotension, or cardiac arrest.
Choice C reason: Puerperal infection is not the correct answer, as it is a bacterial infection of the reproductive tract that occurs after childbirth. Puerperal infection can occur as a complication of abruptio placentae, but it is not indicated by the petechiae or bleeding around the IV access site. Puerperal infection would cause fever, foul-smelling lochia, or pelvic pain.
Choice D reason: Disseminated intravascular coagulation is the correct answer, as it is a coagulation disorder that causes widespread clotting and bleeding in the body. Disseminated intravascular coagulation can occur as a complication of abruptio placentae, and it is indicated by the petechiae and bleeding around the IV access site. Disseminated intravascular coagulation would also cause a low platelet count, a prolonged prothrombin time (PT) and activated partial thromboplastin time (aPTT), and a low fibrinogen level.
Correct Answer is A
Explanation
Choice A reason: This statement is correct, as the ultrasound can help diagnose placenta previa, which is a condition where the placenta covers the cervical opening and can cause painless, bright red bleeding in the third trimester. Placenta previa is a serious complication that can affect the delivery and the fetal oxygenation.
Choice B reason: This statement is incorrect, as the biparietal diameter is a measurement of the fetal head that is used to estimate the gestational age and the fetal growth. The biparietal diameter is not related to the cause or the severity of the bleeding.
Choice C reason: This statement is incorrect, as the fetal lung maturity is an assessment of the surfactant level in the amniotic fluid that is used to predict the risk of respiratory distress syndrome in preterm infants. The fetal lung maturity is not related to the cause or the severity of the bleeding.
Choice D reason: This statement is incorrect, as the viability of the fetus is an evaluation of the fetal heart rate, movement, and tone that is used to determine the fetal well-being and distress. The viability of the fetus is not related to the cause or the severity of the bleeding, although it can be affected by it.
