Correct Answer: D

Rationale: The correct answer is a client who has a diagnosis of preeclampsia reporting epigastric pain and an unresolved headache. These symptoms indicate severe preeclampsia, which requires immediate medical attention due to the potential risks of complications such as HELLP syndrome or eclampsia. The other options describe concerning situations but do not represent immediate life-threatening conditions like those seen in severe preeclampsia.

Correct Answer: B

Rationale: A respiratory rate of 16/min within the normal range is an essential parameter to monitor when administering magnesium sulfate, as respiratory depression is a potential adverse effect. Diminished deep-tendon reflexes may indicate magnesium toxicity, warranting immediate intervention. A urine output of 50 mL in 4 hours is below the expected amount, suggesting decreased kidney perfusion, which can be exacerbated by magnesium sulfate. A heart rate of 56/min is bradycardic and may indicate magnesium toxicity, requiring assessment and possible discontinuation of the infusion.

Correct Answer: C

Rationale: Performing an internal examination in a client with placenta previa can lead to significant bleeding due to the proximity of the placenta to the cervical os. This bleeding can be severe and potentially life-threatening. Therefore, it is crucial to avoid any unnecessary manipulation that could disrupt the delicate balance and lead to hemorrhage.

Correct Answer: C

Rationale: Polyhydramnios refers to the presence of an excessive amount of amniotic fluid around the fetus. This condition can result from various causes, such as maternal diabetes, fetal anomalies, or genetic disorders. It can lead to complications during pregnancy and delivery, such as preterm labor, placental abruption, or fetal malpresentation. Understanding this diagnosis is crucial for providing appropriate care and monitoring to ensure the best outcomes for both the mother and the fetus.

Correct Answer: C

Rationale: Assessing respiratory status every 4 hours is not a priority for a client with severe gestational hypertension. In this scenario, the focus should be on monitoring blood pressure, assessing for signs of preeclampsia, administering medications like magnesium sulfate for seizure prophylaxis, and ensuring that calcium gluconate is readily available in case of magnesium toxicity. Respiratory status assessment is important in other conditions but is not directly related to managing severe gestational hypertension.
