A primigravida client at 40 weeks gestation is in active labor. Her cervix is 6 cm dilated, 100% effaced, and the fetal head is at -1 station. The fetal heart rate shows late decelerations with each contraction. What is the nurse's priority action?

Late decelerations indicate uteroplacental insufficiency and fetal hypoxia, requiring immediate provider notification for potential emergency intervention. Supportive measures like position change, IV fluids, or oxygen are secondary priorities.

Core Nursing Explanation Key Concept Analysis: This question tests the nurse's ability to recognize and prioritize care for a critical Fetal Heart Rate (FHR) pattern during labor. Late decelerations are a non-reassuring pattern characterized by a gradual decrease in the FHR that begins after the peak of a uterine contraction and returns to baseline after the contraction ends. The key pathophysiology is Key Point! Uteroplacental insufficiency (UPI). During a contraction, blood flow to the intervillous space of the placenta is temporarily reduced. In UPI, this reduction is severe enough to cause fetal hypoxia and acidosis. Late decelerations are a direct reflection of this hypoxic stress on the fetus.

Answer Rationale: The correct answer is to Key Point! Notify the healthcare provider immediately. In the context of active labor with late decelerations, this is a Category II or III FHR tracing (depending on variability), signaling potential fetal compromise. The nurse's primary responsibility is to initiate the chain of command to facilitate interventions that may include intrauterine resuscitation, preparation for an emergency cesarean section, or other actions that require a provider's order or presence. Immediate notification is the priority action to mobilize the necessary resources for the fetus.

Distractor Analysis:
Watch out for confusion! While options 1, 2, and 4 are all appropriate supportive or intrauterine resuscitation measures, they are secondary to notifying the provider when a clear non-reassuring pattern like late decelerations is present. The nurse may initiate some of these simultaneously or immediately after calling, but the act of notification takes precedence to ensure a rapid, coordinated team response.
- Option 1 (Position change): Changing the client's position (e.g., to left lateral) can improve uteroplacental perfusion and is a first-line supportive measure, but it does not replace the need for urgent provider notification.
- Option 2 (Increase IV fluids): Hydration can improve maternal cardiac output and placental perfusion. However, this is a corrective action that follows the critical step of alerting the team.
- Option 3 (Notify provider): CORRECT. This is the priority action to ensure a timely, higher-level intervention.
- Option 4 (Apply oxygen): Administering oxygen to the mother (typically via non-rebreather mask at 10-15 L/min, not a nasal cannula at 2 L/min) increases maternal oxygen saturation, which may slightly improve fetal oxygenation. Again, this is part of intrauterine resuscitation but is not the first priority when a clear threat is identified.

Related Concepts: The management of non-reassuring FHR patterns follows the principles of intrauterine resuscitation: Position change (left lateral), Oxygen administration, IV fluid bolus, Discontinuation of oxytocin (if infusing), and Notification of the provider (POODN). The nurse must understand the differences between early, variable, and late decelerations, as their management priorities differ.

Nursing Clinical Practice Guide Clinical Scenario: You are the labor nurse for Anna, a 40-week primigravida. As you monitor her strip, you note that with each contraction, the FHR drops from a baseline of 140 bpm to 110 bpm, starting at the peak of the contraction and recovering slowly after it ends. The variability is minimal. Anna is contracting every 3 minutes.

Nursing Intervention Strategy: 1. Assessment: Immediately confirm the tracing. Check maternal vital signs, especially blood pressure (to rule out hypotension). Note contraction frequency and strength. Perform a vaginal exam only if it is safe and will not delay critical actions. 2. Immediate Action (Priority): Call the provider (OB/GYN, midwife) to the bedside STAT. Verbally report: "I have a patient in active labor with recurrent late decelerations and minimal variability." 3. Simultaneous Intrauterine Resuscitation: While waiting for the provider, you can and should initiate: - Positioning: Assist Anna to a left lateral or knee-chest position. - Oxygen: Apply a non-rebreather mask at 10-15 L/min (a nasal cannula at 2 L/min is insufficient for this situation). - IV Fluids: If an IV is in place, open the line to a rapid bolus of Lactated Ringer's or Normal Saline as ordered or per protocol. - Medication: If oxytocin (Pitocin) is infusing, stop it immediately. 4. Preparation: Anticipate and prepare for possible interventions: ensure the operating room is notified if a cesarean section is likely, gather equipment for a possible assisted vaginal delivery, and have neonatal resuscitation equipment ready.

Patient Safety and Precautions: - Communication is Critical: Use clear, closed-loop communication. Document the time of notification, the provider's name, the actions taken, and the fetal response. - Do Not Delay: Do not spend excessive time trying to correct the pattern with supportive measures before notifying the provider. The clock starts when the non-reassuring pattern is identified. - Correct Oxygen Delivery: For suspected fetal hypoxia, high-flow oxygen via a tight-fitting non-rebreather mask is standard. A nasal cannula delivers a low, variable fraction of inspired oxygen (FiO2) and is not appropriate.

Nursing Procedure & Medication Flow Procedure: Responding to Late Decelerations 1. Identify the pattern (gradual decrease, late onset, late return). 2. Assess maternal condition (BP, position, fluid status). 3. NOTIFY PROVIDER IMMEDIATELY. 4. Initiate intrauterine resuscitation measures (POODN). 5. Continuously monitor FHR and uterine activity for response. 6. Document everything meticulously: pattern description, actions taken, times, provider notification, and patient/fetal response.

Medication Note: Oxytocin (Pitocin) - If oxytocin is infusing, it is a common cause of hyperstimulation (tachysystole) leading to late decelerations. Stopping the infusion is a key nursing action. - Know your facility's protocol for managing tachysystole, which often includes position change, IV fluids, and oxygen in addition to discontinuing oxytocin.

A Word from Your Senior Nurse "Remember, in labor and delivery, you are caring for two patients. A late deceleration is the fetus's cry for help, telling you it's not getting enough oxygen. Your most powerful tool is not just your clinical skill but your voice. Speaking up quickly and clearly to get the right people in the room can make the difference between a good outcome and a catastrophic one. On the NCLEX, they are testing your judgment: can you recognize what requires an immediate team response versus what you can manage independently? Always err on the side of safety and communication."
