A patient diagnosed with preeclampsia is admitted to the hospital and prescribed magnesium sulfate therapy.
What is the purpose of administering magnesium sulfate to this patient?
To decrease her blood pressure.
To decrease her tidal volume.
To prevent her from becoming dehydrated.
To prevent her from having convulsions.
The Correct Answer is D
The correct answer is choice D: To prevent her from having convulsions. Magnesium sulfate is a mineral that reduces seizure risks in women with preeclampsia, a condition of high blood pressure and protein in the urine during pregnancy. Magnesium sulfate can lower the cerebral perfusion pressure and prevent convulsions. However, magnesium sulfate does not affect the neonatal outcomes and can cause side effects such as respiratory depression.
Choice A is wrong because magnesium sulfate does not decrease blood pressure. It is used along with medications that help reduce blood pressure.
Choice B is wrong because magnesium sulfate does not decrease tidal volume. It can cause respiratory depression if the serum level is too high.
Choice C is wrong because magnesium sulfate does not prevent dehydration. It can cause fluid retention and pulmonary edema if given in excess.

Correct Answer is D
Explanation
The correct answer is choice D. Leaning slightly backwards when walking can increase the curvature of the lower spine and worsen back pain.
The other choices are helpful methods to alleviate back pain during pregnancy.
Choice A is correct because pelvic tilt exercises can strengthen the abdominal muscles and reduce the strain on the lower back.
Choice B is correct because wearing shoes with low heels can improve posture and balance and prevent excessive arching of the lower back.
Choice C is correct because sleeping on the side with a pillow beneath the knees can support the spine and pelvis and relieve pressure on the lower back.
Normal ranges for back pain during pregnancy vary depending on the individual, but some common factors that can affect it are weight gain, hormonal changes, center of gravity shift, stress and muscle separation.
