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?

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 white blood cell count of 12,000/mm3 indicates an infection that can trigger pre-term labor.The normal range for white blood cell count in pregnancy is 5.7-15.0×10 9 /L, which is equivalent to 5,700-15,000/mm3.

A count above this range suggests an inflammatory response to an infection.

Choice B is wrong because a hemoglobin level of 11 g/dL is within the normal range for pregnancy, which is 10-14 g/dL.

Choice C is wrong because a platelet count of 250,000/mm3 is within the normal range for pregnancy, which is 150,000-400,000/mm3.

Choice D is wrong because a blood glucose level of 90 mg/dL is within the normal range for pregnancy, which is 70-110 mg/dL.
