A nurse is assisting in the care of a client at 28 weeks of gestation who has preeclampsia with severe features and is receiving intravenous magnesium sulfate.
Which of the following indications should the nurse recognize as the reasons for the client receiving this medication?

Choice A rationale

Expectant management protocols involve close monitoring and delaying delivery to allow for fetal maturation, typically used in stable preeclampsia before 34 weeks. However, this client has preeclampsia with severe features and worsening manifestations at 35 weeks, making immediate delivery the medically indicated course of action to prevent maternal stroke or seizure. Expectant management is no longer appropriate when the maternal condition is deteriorating, as the only definitive cure for the disease is delivery.

Choice B rationale

The method of birth refers to the choice between a vaginal delivery and a cesarean section. While this is an important clinical decision, the question focuses on the psychological distress of the client regarding their disregarded birth plan. Simply deciding the method of birth does not address the lack of autonomy the client feels. The medical priority is the induction for safety, but the nurse must find ways to integrate the client's preferences within those safety constraints.

Choice C rationale

Shared decision-making is a collaborative process that allows the client and healthcare team to make decisions together, even in emergency or high-risk situations. By implementing this, the nurse can explain the medical necessity of the induction while asking the client which parts of their original birth plan can still be honored, such as lighting, music, or support persons. This reduces the client's sense of powerlessness and ensures they remain an active participant in their care.

Choice D rationale

Antenatal steroid administration, such as betamethasone, is used to enhance fetal lung maturity in pregnancies less than 34 weeks of gestation when preterm birth is imminent. Since this client is currently at 35 weeks of gestation, the benefit of steroids is significantly diminished, and the urgent need for delivery due to worsening severe preeclampsia features takes precedence. Administering steroids does not address the client's emotional distress or the conflict regarding the birth plan.

Choice A rationale

Hashimoto's disease is an autoimmune disorder where the immune system attacks the thyroid gland, leading to chronic inflammation and eventual glandular failure. This is the most common cause of primary hypothyroidism in iodine-sufficient regions. During pregnancy, pre-existing Hashimoto's increases the risk of overt hypothyroidism, which requires close monitoring of thyroid stimulating hormone and thyroxine levels to prevent adverse maternal or fetal outcomes. Normal TSH during the first trimester is generally 0.1 to 2.5 mIU/L.

Choice B rationale

Helicobacter pylori is a gram-negative bacterium that primarily colonizes the stomach and is associated with peptic ulcer disease and gastritis. While some research suggests a potential link between chronic infections and various autoimmune processes, there is no established direct causal link between H. pylori and the development of hypothyroidism in the prenatal population. The primary risk factors for hypothyroidism remain autoimmune thyroiditis, iodine deficiency, or prior thyroid surgery or radiation therapy.

Choice C rationale

The GDF15 gene is associated with the production of growth differentiation factor 15, which plays a role in regulating nausea and vomiting during pregnancy. Mutations or variations in this gene have been linked to an increased risk of developing hyperemesis gravidarum. It does not have a known pathological connection to thyroid gland dysfunction or the development of hypothyroidism. Therefore, a client with this mutation would be monitored for severe emesis rather than thyroid insufficiency.

Choice D rationale

Low levels of thyroid stimulating hormone combined with elevated levels of free thyroxine are diagnostic indicators of hyperthyroidism, not hypothyroidism. This state of thyroid overactivity can occur in pregnancy due to Graves' disease or human chorionic gonadotropin-mediated stimulation of the thyroid. In contrast, hypothyroidism would present with an elevated TSH and a low T4 level. Normal free T4 levels in adults generally range from 0.8 to 2.8 ng/dL depending on the lab.
