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. Caloric intake should be 300 calories above the suggested non-pregnant caloric intake.This is because women with gestational diabetes need to meet the nutritional needs of pregnancy and also control their blood glucose levels.
Choice A is wrong because carbohydrates should make up about 45% of the total dietary intake for women with gestational diabetes, not 25%.
Carbohydrates are important for providing energy and nutrients for the mother and the baby.
Choice B is wrong because animal protein can be included in the pre-bedtime snack as long as it is combined with some carbohydrates.
Protein can help prevent low blood glucose levels during the night.
Choice D is wrong because sugar substitutes do not help to control blood glucose levels.They may also have adverse effects on the baby’s development.Women with gestational diabetes should limit their intake of added sugars and choose foods with natural sugars instead.
