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?

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.

A cervical cerclage is a procedure that involves placing stitches around the cervix to prevent it from opening prematurely.This procedure is usually done for women who have a history of cervical insufficiency or a short cervix, which are risk factors for preterm labor.

Choice A is wrong because history of gestational diabetes is not a risk factor for preterm labor.

Gestational diabetes is a condition that causes high blood sugar during pregnancy and can affect the health of the mother and the baby, but it does not increase the risk of preterm labor.

Choice C is wrong because history of recurrent urinary tract infections (UTIs) is a risk factor for preterm labor.

UTIs are infections that affect the urinary system and can cause symptoms such as pain, burning, or frequent urination.

UTIs can also spread to the kidneys or the uterus and cause inflammation or infection that can trigger preterm labor.

Choice D is wrong because history of assisted reproductive technology (ART) is a risk factor for preterm labor.

ART refers to any medical procedure that helps with conception, such as in vitro fertilization (IVF).

ART can increase the risk of preterm labor because it can result in multiple gestations (twins, triplets, or more), which put more strain on the uterus and can cause it to contract prematurely.ART can also cause complications such as placenta previa or rupture of the uterus, which can lead to preterm labor.
