A primigravida client at 38 weeks gestation arrives at the emergency department with strong, frequent contractions that began 45 minutes ago. Upon examination, the cervix is 8 cm dilated and 100% effaced. The fetal heart rate is 140 bpm with good variability. What is the nurse's priority action?

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.

Clinical Context

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.
