A 32-year-old woman at 34 weeks gestation presents to the emergency department with sudden onset of severe abdominal pain and vaginal bleeding. Her vital signs are: BP 90/60 mmHg, HR 120 bpm, RR 24/min. The fetal heart rate shows late decelerations with decreased variability. Abruptio placentae is suspected. What is the nurse's highest priority action?

Situation: A 34-week gravid patient presents with sudden severe abdominal pain, vaginal bleeding, hypotension (90/60 mmHg), tachycardia (120 bpm), and a non-reassuring fetal heart tracing (late decelerations, decreased variability). Abruptio placentae is suspected.

Immediate Nursing Priority: Recognize this as a crash cesarean section (CCS) scenario. The highest priority is to activate the obstetric emergency team and prepare the patient for immediate cesarean delivery. The goal is decision-to-delivery within 30 minutes.

Simultaneous Actions (Team-Based): While one nurse notifies the provider and surgical team, other team members should concurrently:

• Establish two large-bore IV lines and initiate fluid resuscitation with crystalloids (e.g., Lactated Ringer's) to combat hypovolemic shock.
• Administer oxygen via a non-rebreather mask at 10-15 L/min to maximize maternal oxygenation and fetal oxygen delivery.
• Position the patient in a left lateral tilt to relieve aortocaval compression and improve uteroplacental blood flow.
• Insert an indwelling urinary catheter to monitor output and prepare the surgical field.
• Collect blood samples for type and crossmatch, complete blood count, and coagulation studies (monitor for disseminated intravascular coagulation).

Rationale for Surgical Priority: Definitive treatment for placental abruption with maternal hemodynamic instability and fetal distress is delivery. Supportive measures (oxygen, fluids, positioning) are critical but do not stop the ongoing placental separation and hemorrhage. Delaying surgery increases the risk of maternal exsanguination, fetal demise, and coagulopathy.

Key Clinical Pearl: In abruptio placentae, the amount of external vaginal bleeding often underestimates the true blood loss due to concealed hemorrhage behind the placenta. Always anticipate and prepare for massive transfusion protocols.
