A nurse is caring for a client who is receiving magnesium sulfate for pre-term labor.

Which of the following assessments should the nurse perform to evaluate the therapeutic effect of the medication?

Blood pressure of 150/90 mmHg.This is because terbutaline can causeelevated blood pressureas a side effect.

The nurse should report this finding to the provider as it may indicate hypertension or a hypertensive crisis.

Choice A is wrong because a heart rate of 110/min is not abnormal for a person who has received terbutaline.Terbutaline can causefast or pounding heartbeatsas a common side effect.

Choice C is wrong because a blood glucose of 90 mg/dL is within the normal range of 70-130 mg/dL before meals.Terbutaline can causetransient hyperglycemia(high blood sugar) as a serious side effect, but this is not the case here.

Choice D is wrong because a temperature of 37°C (98.6°F) is normal for a human being.Terbutaline does not cause fever or hypothermia as a side effect.

The client should not limit their physical activity and rest as much as possible, unless advised by their provider.Excessive rest and inactivity can increase the risk of blood clots and decrease blood circulation, which can affect the placenta and the fetus.The client should follow the recommended guidelines for physical activity during pregnancy, unless they have a medical condition that requires bed rest or reduced activity.

Choice A is wrong because smoking and drinking alcohol during pregnancy are known risk factors for preterm labor and birth.Smoking can reduce blood flow to the placenta and affect fetal growth and development, while alcohol can cause fetal alcohol spectrum disorders and other complications.

Choice B is wrong because reporting any vaginal bleeding or fluid leakage to the provider is important to prevent or treat preterm labor and birth.Bleeding can indicate placenta previa or placental abruption, which are serious conditions that can cause premature delivery or fetal distress.Fluid leakage can indicate rupture of membranes, which can increase the risk of infection and preterm labor.

Choice D is wrong because drinking plenty of fluids and eating a balanced diet are beneficial for the health of the mother and the fetus.Dehydration can cause uterine contractions and trigger preterm labor, while malnutrition can affect fetal growth and development.A balanced diet can also help prevent or manage conditions like diabetes, high blood pressure, and anemia, which are risk factors for preterm labor and birth.
