A nurse is caring for a client who is at 35 weeks of gestation and has pre-term labor with intact membranes and no signs of infection.

The provider prescribes indomethacin to inhibit prostaglandin synthesis and suppress uterine contractions.

Which of the following laboratory tests should the nurse monitor while the client is receiving this medication?

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.

Nifedipine is a calcium channel blocker that is used to relax uterine contractions and postpone preterm labor.However, it can also lower blood pressure and cause side effects such as headache, dizziness, flushing, and palpitations.Therefore, it should be avoided in clients who have cardiac disease or other conditions that affect the heart function.

Choice A is wrong because asthma is not a contraindication for nifedipine.Nifedipine does not affect the airways or cause bronchospasm.

Choice B is wrong because diabetes mellitus is not a contraindication for nifedipine.Nifedipine does not affect blood glucose levels or insulin secretion.

Choice C is wrong because hypertension is not a contraindication for nifedipine.In fact, nifedipine can be used to treat high blood pressure as well as preterm labor.However, blood pressure should be monitored closely during nifedipine therapy to avoid hypotension.
