A 32-year-old at 34 weeks presents to the ED with severe abdominal pain, tense abdomen, and vaginal bleeding after cocaine use. FHR shows late decelerations and minimal variability. What is the nurse's immediate priority?

Rationale: A. Preparing the client for emergency delivery is the immediate priority because the symptoms—severe abdominal pain, tense abdomen, vaginal bleeding, and fetal heart rate changes (late decelerations and minimal variability)—indicate placental abruption with fetal compromise, which is an obstetric emergency. Rapid delivery is critical to prevent maternal and fetal morbidity and mortality. B. Inserting a Foley catheter is important for monitoring urine output but is secondary to stabilizing maternal and fetal status. C. Providing relaxation techniques and emotional support is supportive care but does not address the acute, life-threatening condition. D. Administering IV magnesium sulfate for fetal neuroprotection is indicated in preterm deliveries for neuroprotection, but stabilizing the immediate threat from placental abruption takes precedence.
