When teaching a prenatal class, the nurse realizes that some of the material must be reviewed when one of the dads says that many sexually transmitted infections are transmissible during delivery. The mother might need a cesarean section at the time of delivery to avoid transmission through breastfeeding. Which of the following statements is true?

Choice A rationale

Decrease proteinuria is not the primary goal for magnesium sulfate therapy. It's an indicator of kidney function and hypertension severity. Therapy focuses on neuroprotection and seizure prevention. Proteinuria reflects preeclampsia's renal impact, not neuroprotection.

Choice B rationale

Prevent maternal seizures is magnesium sulfate's primary goal. It stabilizes neuronal membranes, reducing seizure risk in severe preeclampsia. By inhibiting NMDA receptors and calcium channels, it prevents seizures, critical for maternal-fetal safety.

Choice C rationale

Reduce deep tendon reflexes is not magnesium sulfate's primary goal, but a side effect. It signifies therapeutic levels, indicating potential toxicity. Reflex reduction helps assess magnesium toxicity risk, ensuring safe neuroprotective dosing.

Choice A rationale

Persistent nausea and vomiting are common during the first trimester, but not to the extent seen in hyperemesis gravidarum, which involves severe and prolonged symptoms leading to dehydration and weight loss.

Choice B rationale

Hyperemesis gravidarum's exact cause is unknown, making it difficult to prevent. Risk factors include multiple pregnancies and a history of the condition, but no definitive prevention measures are established.

Choice C rationale

The chronic nausea, vomiting, and resultant physical debilitation of hyperemesis gravidarum significantly impact the quality of life, leading to anxiety and depression due to the persistent nature of the symptoms.

Choice D rationale

Hospitalization for rehydration and electrolyte balance restoration is often necessary for hyperemesis gravidarum due to severe dehydration from persistent vomiting and inability to retain fluids and nutrients.
