A nurse is providing teaching about the expected effects of magnesium sulfate to a client who is at 28 weeks of gestation and has preeclampsia. Which of the following responses by the nurse is appropriate?
"This medication stabilizes the fetal heart rate."
"This medication prevents seizures."
"This medication increases cardiac output."
This medication improves tissue perfusion."
The Correct Answer is B
Magnesium sulfate is used to prevent seizures in clients with preeclampsia. It works by relaxing the smooth muscles and blocking neuromuscular transmission. While magnesium sulfate can indirectly improve fetal heart rate and tissue perfusion by preventing seizures, it does not directly stabilize the fetal heart rate or increase cardiac output.

Correct Answer is D
Explanation
Abdominal ultrasounds are noninvasive imaging tests that use high-frequency sound waves to create images of the internal organs. When an abdominal ultrasound is performed, the client is typically asked to drink water before the test and to hold the urine to ensure that the bladder is full. This full bladder helps to create a clear image of the uterus and the developing fetus.
Option A is incorrect because applying perfumed lotion to the abdomen can interfere with the ultrasound waves and may affect the quality of the images.
Option B is also incorrect because having an empty stomach is not necessary for an abdominal ultrasound.
Option C is also incorrect because a stool softener is not necessary for an abdominal ultrasound.
Correct Answer is D
Explanation
The nurse should withhold the terbutaline and report to the provider if the client's blood pressure is 88/58 mm Hg. Terbutaline can cause hypotension, and a blood pressure reading in this range indicates the client is already experiencing low blood pressure. The provider may need to adjust the medication dosage or consider an alternative medication.
The other findings are within normal ranges and would not require withholding the medication or reporting to the provider:
Fasting blood glucose of 75 mg/dL is within the normal range.
FHR of 120/min is within the normal fetal heart rate range.
Urinary output of 40 ml/hr is within normal range, although it should be monitored for any signs of decreased urine output as this could indicate dehydration.
