A nurse is reviewing the ultrasound report of a client who is at 31 weeks of gestation and has pre-term labor.

Which of the following findings indicates oligohydramnios?

Magnesium sulfate is a drug that is used to prevent seizures associated with pre-eclampsia and to stop preterm labor.However, it can also cause adverse effects such as respiratory depression, which is a condition where the breathing rate becomes too slow and shallow.

Respiratory depression can be life-threatening for both the mother and the baby, so the nurse should monitor the client’s respiratory rate and oxygen saturation closely.

Choice A is wrong because magnesium sulfate can cause hypotension, not hypertension.Hypotension is low blood pressure, which can lead to dizziness, fainting, and shock.

Choice B is wrong because magnesium sulfate can cause hyporeflexia, not hyperreflexia.Hyporeflexia is a reduced or absent reflex response, which can indicate magnesium toxicity.

The nurse should check the client’s deep tendon reflexes regularly and stop the infusion if they are absent.

Choice D is wrong because magnesium sulfate can cause bradycardia, not tachycardia.

Bradycardia is a slow heart rate, which can reduce the blood flow to vital organs.

Drinking enough water can help prevent dehydration, which can trigger preterm labor contractions.Dehydration can also cause low amniotic fluid levels, which can affect fetal growth and development.

Choice A is wrong because avoiding sexual intercourse until term is not necessary for most women at risk for preterm labor.Sexual activity does not cause preterm labor unless there are other complications, such as placenta previa or cervical insufficiency.

Choice C is wrong because lying down when feeling contractions may not stop preterm labor.If a woman has regular contractions that cause cervical change, she should seek medical attention as soon as possible.Lying down may also reduce blood flow to the uterus and placenta, which can affect fetal oxygenation.

Choice D is wrong because taking aspirin for pelvic pain is not recommended for pregnant women.Aspirin can increase the risk of bleeding and affect fetal blood circulation.

Pelvic pain may be a sign of preterm labor or other complications, so it should be evaluated by a health care provider
