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.

Answer and Explanation

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. Insufficient relaxation of the uterus between contractions.This is also known astachysystoleorhyperstimulation, which can cause fetal distress and uterine rupture.Oxytocin is a hormone that stimulates uterine contractions, but it can also cause them to be too strong or too frequent if given in high doses or for too long.

Choice A is wrong because oxytocin does not decrease body temperature.

Choice B is wrong because oxytocin does not cause maternal cardiac arrhythmias.

Choice C is wrong because oxytocin does not cause urinary retention.

A. Remind her that an increase in fetal activity will require an increase in her need to rest. B. Explain to her that she is likely to have back labor. C. Arrange for her to meet the staff who will be caring for her during labor and delivery. D. Teach her how to test her urine for the presence of glucose.

Correct Answer is C

Explanation

The correct answer is choice C. Arrange for her to meet the staff who will be caring for her during labor and delivery.This measure can help reduce the anxiety and fear of the unknown that a primigravida may have in the last month of pregnancy.Meeting the staff can also help establish rapport and trust, which are essential for a positive birth experience.

Choice A is wrong because an increase in fetal activity does not necessarily require an increase in the need to rest.

Fetal activity is normal and expected, and the mother should monitor it regularly.Resting may help with some discomforts of pregnancy, but it is not directly related to fetal activity.

Choice B is wrong because back labor is not likely for a primigravida with an uncomplicated pregnancy.

Back labor occurs when the fetus is in an occiput posterior position, which puts pressure on the mother’s spine and causes intense pain in the lower back.This position is more common in multiparous women than primigravidas.

Choice D is wrong because testing urine for glucose is not a routine measure for a primigravida with an uncomplicated pregnancy.

Urine glucose testing is done for women who have gestational diabetes or are at risk of developing it.It is not necessary for women who have normal blood glucose levels.
