A nurse is monitoring a client who is at 29 weeks of gestation and has pre-term labor.

The client is receiving magnesium sulfate IV infusion.

Which of the following are expected adverse effects of this medication? (Select all that apply)

Tachycardia.

Terbutaline is a medication that can be used to stop or delay preterm labor by relaxing the uterine muscles.However, it can also cause serious side effects for both the mother and the baby.One of the most common side effects of terbutaline is tachycardia, which means a fast or irregular heartbeat.This can lead to chest pain, palpitations, shortness of breath, and even cardiac arrhythmias or ischemia.

Therefore, the nurse should monitor the mother’s heart rate and rhythm closely when administering terbutaline.

Choice A is wrong because terbutaline does not cause hypotension, which means low blood pressure.In fact, terbutaline can increase blood pressure by constricting blood vessels.

Choice C is wrong because terbutaline does not cause hyperglycemia, which means high blood sugar.However, terbutaline can interfere with insulin secretion and glucose metabolism in some cases, especially in diabetic mothers.

Therefore, the nurse should monitor the mother’s blood sugar levels when administering terbutaline.

Choice D is wrong because terbutaline does not cause hypokalemia, which means low potassium levels in the blood.However, terbutaline can cause a temporary increase in potassium levels in the baby, which can affect the baby’s heart function.

Therefore, the nurse should monitor the baby’s heart rate and rhythm when administering terbutaline.

Normal ranges for heart rate are 60 to 100 beats per minute for adults and 120 to 160 beats per minute for fetuses.

Normal ranges for blood pressure aretypically between 90/60 mmHg and 120/80 mmHg.

Betamethasone is a corticosteroid that is given to pregnant women who are at risk of preterm labor to improve neonatal outcomes.Betamethasone stimulates the production of surfactant, a substance that lubricates the lungs and prevents them from collapsing after birth.This reduces the risk of respiratory distress syndrome, a common complication of preterm birth.

Choice B is wrong because betamethasone does not decrease the risk of infection in the newborn.In fact, it may increase the risk of maternal and neonatal infections by suppressing the immune system.

Choice C is wrong because betamethasone does not increase blood glucose levels in the newborn.However, it may cause transient hyperglycemia in the mother, which should be monitored and treated if necessary.

Choice D is wrong because betamethasone does not decrease the risk of bleeding in the newborn.It may increase the risk of intraventricular hemorrhage, a type of bleeding in the brain, if given before 24 weeks of gestation.Therefore, it should be used with caution in this population and only after a family’s decision regarding resuscitation.
