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 B
Explanation
he correct answer is choice B. Sufficient perfusion and circulation of the fetus.This is because the fetal heart rate is within the normal range of 110 to 160 beats per minute, and there is moderate beat-to-beat variability, which indicates a healthy nervous system.
Choice A is wrong because insufficient perfusion of the placenta would cause fetal distress and abnormal fetal heart rate patterns, such as late decelerations or minimal variability.
Choice C is wrong because maternal hypoxia would not directly affect the fetal heart rate, unless it leads to placental insufficiency or uterine hyperstimulation.
Choice D is wrong because fetal hypoxia would cause signs of fetal distress, such as tachycardia, bradycardia, or absent variability.
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.
