해설
With 8 cm dilation and complete effacement after only 45 minutes of labor, delivery is imminent in precipitous labor. The nurse's priority is to prepare for emergency delivery, as transfer may not be safe or timely. Other options are inappropriate: ambulation may not slow rapid labor, tocolytics are contraindicated, and transfer risks delivery en route.
This scenario describes a primigravida client at term (38 weeks) in active labor. The assessment reveals a cervix that is 8 cm dilated and 100% effaced, with contractions that are strong and frequent. The fetal heart rate is 140 bpm with good variability, indicating a well-oxygenated fetus. This clinical picture places the client in the transition phase of the first stage of labor, rapidly approaching the second stage (delivery).
Priority Action Analysis
The nurse's priority is to ensure a safe delivery for both the client and the newborn. The rapid progression of labor makes an imminent delivery highly likely.
- Option 1 (Encourage ambulation): This is contraindicated. A cervix dilated to 8 cm in a primigravida with strong, frequent contractions signals advanced labor. Ambulation will not slow progression and could increase the risk of an unassisted delivery or a fall.
- Option 2 (Prepare for imminent delivery): This is the correct priority action. The assessment data points to an imminent birth. The nurse must immediately prepare the environment by ensuring emergency delivery supplies (e.g., a delivery pack, infant warmer, suction equipment, and supplies for managing postpartum hemorrhage) are at the bedside and functional. The concept of readiness planning is critical in such time-sensitive obstetric emergencies. A study on interfacility transport highlights that the progression of labor can be rapid, and a key safety measure is recognizing when delivery is too imminent to move a patient [3]. This principle applies directly here; the priority is to prepare for delivery at the current location rather than risking transport. The foundational step in managing any obstetric emergency is ensuring that the necessary equipment and trained personnel are immediately available to perform front-line clinical performance [4].
- Option 3 (Administer tocolytics): This is contraindicated and dangerous. Tocolytics are used to suppress preterm labor, not to halt term labor at 8 cm dilation. Administration would be ineffective and could cause adverse maternal and fetal effects.
- Option 4 (Transfer to labor and delivery unit): While the client will eventually need to be in the labor and delivery unit, immediate transfer is unsafe when delivery is imminent. The risk of delivery during transport is high. The priority is to stabilize the situation and prepare for delivery in the current setting. Research on interfacility transport confirms that a primary risk is delivery prior to or within one hour of arrival due to the progression of labor [3]. The nurse must first prepare for an emergency delivery and then, if time and the client’s condition permit, arrange a safe transfer. The capability to manage an obstetric emergency begins with immediate, on-site preparation, a key finding from emergency department readiness assessments .
Clinical Reasoning and Evidence Connection
The correct action is rooted in the principles of emergency obstetric readiness. When a patient presents with advanced cervical dilation and strong contractions, the clinical team must immediately shift from a transport-focused mindset to a delivery-preparation mindset. The assessment findings (8 cm dilation, 100% effacement) are strong predictors of an imminent delivery, and the primary outcome to avoid is an unplanned, unassisted birth in a non-optimal setting [3]. The nurse’s immediate action of preparing emergency delivery supplies directly addresses this risk by creating a safer environment for the impending birth. This action is a direct application of readiness planning, which moves beyond theoretical knowledge to ensure that front-line performance, such as managing an imminent delivery, can be executed effectively with the correct tools at hand [4]. While non-invasive intrapartum interventions like repositioning are used for abnormal fetal heart rate patterns , the reassuring fetal heart rate in this scenario (140 bpm with good variability) does not necessitate such measures, allowing the nurse to focus entirely on the mechanical preparation for the birth itself.

Clinical Practice Guide: Managing Imminent Delivery in the Emergency Department
Rapid Assessment for Imminent Birth
Recognize Transition Phase: Cervical dilation of 8 cm or more with 100% effacement and strong, frequent contractions (every 2-3 minutes, lasting 60-90 seconds) indicates the transition phase of the first stage of labor. Birth is likely within minutes to an hour, even for a primigravida.
Maternal Signs: The client may express an urge to push, have rectal pressure, or become restless and focused inward. Do not leave the client unattended.
Fetal Well-Being: A fetal heart rate of 110-160 bpm with moderate variability is reassuring. Continuous monitoring should be initiated if equipment is available, but preparation for delivery takes precedence.
Priority Nursing Actions
Do Not Transfer or Ambulate: Keep the client in the current location. Moving a client in advanced labor risks an unassisted delivery in a hallway or elevator. Ambulation is contraindicated.
Call for Help: Immediately notify the obstetrician, certified nurse-midwife, or emergency department provider. Summon additional nursing staff and a neonatal resuscitation team if available.
Prepare Emergency Delivery Supplies: Open a sterile delivery pack. Ensure the following are at the bedside and functional:
Infant warmer with preheated blankets and a hat
Bulb syringe and suction catheter with wall suction set to 80-100 mmHg
Two clamps for the umbilical cord and sterile scissors or scalpel
Supplies for active management of the third stage (oxytocin, controlled cord traction equipment)
Personal protective equipment (gown, gloves with sleeves, face shield)
Position the Client: Assist the client into a comfortable position for delivery (e.g., semi-Fowler's, lithotomy, or left lateral). Elevate the hips with a rolled blanket if delivery is precipitous to provide perineal support.
Provide Perineal Support: During delivery of the head, apply gentle pressure with one hand to control the expulsion and prevent perineal lacerations. Use the other hand to support the perineum with a warm compress.
Post-Delivery Care Considerations
Immediate Newborn Care: Dry and stimulate the infant, place skin-to-skin on the mother's abdomen or chest if stable, and assess Apgar scores at 1 and 5 minutes. Maintain thermoregulation.
Placental Delivery: Observe for signs of placental separation (lengthening of cord, gush of blood, uterine fundus rising). Do not pull on the cord forcefully. Initiate fundal massage after placental expulsion.
Hemorrhage Prevention: Administer oxytocin as per protocol. Monitor uterine tone and lochia closely for the first hour.
Documentation: Record the time of birth, delivery events, maternal and neonatal condition, and any deviations from the planned birth setting.
Primigravida — A woman who is pregnant for the first time.
Effacement — The thinning and shortening of the cervix during labor, expressed as a percentage; 100% means the cervix is completely thinned out.
Transition Phase — The final phase of the first stage of labor, typically from 8 cm to 10 cm dilation, characterized by strong, frequent contractions and rapid cervical change.
Tocolytic Medications — Drugs used to suppress premature uterine contractions in preterm labor; they are not effective or indicated in term active labor.
Imminent Delivery — A situation where birth is about to occur very soon, requiring immediate preparation of supplies and personnel at the bedside.
