A multigravida client at 41 weeks gestation is admitted to the labor and delivery unit. During the initial assessment, the nurse notes that the client is having contractions every 2-3 minutes lasting 50-70 seconds with moderate to strong intensity. The cervix is 7 cm dilated, 80% effaced, and the fetal head is at 0 station. What is the most important assessment the nurse should prioritize at this time?
A 28-year-old primigravida at 40 weeks gestation presents to labor and delivery with regular contractions. Assessment reveals contractions occurring every 3 minutes, lasting 60 seconds with strong intensity. Cervical examination shows 6 cm dilation, 90% effacement, and fetal station at -1. The client appears anxious and states she feels pressure but denies the urge to push.

해설
Continuous fetal monitoring is the priority in active labor to detect fetal distress, as strong frequent contractions can compromise placental blood flow. Other assessments are important but secondary to ensuring fetal well-being.
Core Nursing ExplanationKey Concept Analysis: This question assesses the nurse's ability to prioritize assessments during the active phase of labor. The core theme is fetal surveillance and maternal-fetal safety. The client is in active labor (cervical dilation of 6-7 cm), characterized by strong, frequent contractions. These powerful uterine contractions temporarily reduce blood flow to the placenta (uteroplacental circulation), which can lead to fetal hypoxia if the contractions are too long, too strong, or too frequent. Therefore, the primary nursing responsibility is to ensure fetal well-being by continuously assessing the fetal response to labor.
Answer Rationale: Key Point! The correct answer is Monitor fetal heart rate and contraction pattern continuously. This is the highest priority because it directly evaluates fetal oxygenation and tolerance of labor. The fetal heart rate (FHR) pattern is the most immediate indicator of fetal well-being. Continuous electronic fetal monitoring (EFM) allows for the early detection of non-reassuring patterns (e.g., late decelerations, prolonged bradycardia) that signal potential fetal compromise, enabling timely interventions such as changing maternal position, administering oxygen, or notifying the provider.
Distractor Analysis:
Watch out for confusion! While pain assessment is a component of holistic care, it is not the priority assessment in this scenario. The client's anxiety and reported pressure are common in active labor, but they do not override the need for immediate fetal surveillance.
Vital signs (blood pressure, temperature) are part of routine monitoring but are not the most critical action during the intense, frequent contractions described. Maternal fever could indicate infection (chorioamnionitis), but FHR monitoring would detect fetal tachycardia, an early sign of that condition.
Key Point! This is the correct priority action for fetal safety during active labor.
Hydration status is important to prevent dehydration, which can contribute to dysfunctional labor. However, it is a supportive measure and does not address the acute, direct risk to the fetus posed by the current contraction pattern.
Related Concepts: This question integrates knowledge of the stages of labor, the physiological impact of contractions on fetal oxygenation, and the principles of nursing prioritization (e.g., ABCs—Airway, Breathing, Circulation—with the fetus's "circulation" being paramount). The fetal station (-1 to 0) indicates the head is descending but not yet on the perineum, so the client should be coached not to push until full dilation is confirmed, which is another key nursing action but secondary to initial fetal assessment.
Concept Summary
Concept
Key Takeaway
Active Phase of Labor
Defined as cervical dilation from 6 cm to 10 cm. Contractions are stronger, longer (45-60+ seconds), and closer together (2-5 minutes).
Priority in Active Labor
Continuous fetal monitoring is the top priority to assess fetal tolerance to uterine contractions and prevent hypoxia.
Physiological Mechanism
Uterine contractions compress spiral arteries, temporarily reducing uteroplacental blood flow. Strong/frequent contractions increase the risk of fetal compromise.
Nursing Process
Assessment (FHR/contractions) → Diagnosis (Risk for fetal compromise) → Planning/Implementation (Continuous monitoring, position changes, O2) → Evaluation (FHR pattern improvement).
Continuous electronic fetal monitoring (EFM) is often indicated/required.
Intermittent auscultation may be sufficient for low-risk patients.
Maternal Assessment
Vital signs per protocol; focused on signs of exhaustion or complications.
Comprehensive admission assessment, education, and support.
Anatomy, Physiology & Pharmacology Points
Physiology: The uteroplacental unit is the fetus's life support. Contractions cause a physiologic interruption of blood flow. A healthy fetus has reserves to tolerate this. Non-reassuring FHR patterns indicate those reserves are being depleted.
Station: Fetal station describes the descent of the presenting part through the birth canal relative to the ischial spines. 0 station is at the spines. Negative numbers (-3, -2, -1) are above the spines; positive numbers (+1, +2, +3) are below the spines, indicating descent.
Memory Tips
Acronym: F-MAP for priority in active labor: Fetus (FHR), Mother (contractions), Airway/Breathing (maternal O2 status), Preparation (for delivery). Always start with the Fetus.
Think: Strong contractions = Squeezed placenta. A squeezed placenta needs a nurse watching the baby's heart rate!
High-Frequency NCLEX Topics
Prioritization in obstetric emergencies and active labor is a classic NCLEX theme. The exam tests if you know that the fetus's status is the priority when the mother is in active, strong labor. Questions often combine labor parameters with a need to choose the first or most important action.
Watch Out for Question Variations!
Symptom to Intervention: Instead of "what to assess," it could ask: "The nurse notes late decelerations on the EFM strip. What is the priority intervention?" (Answer: Turn the client to her left side to improve placental perfusion).
Changing the Stage: If the scenario described a client at 10 cm with an irresistible urge to push, the priority shifts to preparing for delivery and coaching pushing efforts, though FHR monitoring remains crucial between pushes.
Nursing Clinical Practice GuideClinical Scenario: You are the nurse admitting "Sarah," a 28-year-old first-time mother, to the labor unit. She is breathing heavily, gripping the bedrail, and says, "The pressure is so intense, I feel like I need to push, but my nurse earlier told me not to." Your quick visual assessment shows a contracting abdomen every 2-3 minutes.
Nursing Intervention Strategy:
Immediate Action (Priority): Assist Sarah to the bed, apply the tocodynamometer (for contractions) and ultrasound transducer (for FHR) for continuous electronic fetal monitoring. Observe the baseline FHR, variability, and for the presence of accelerations or decelerations in relation to contractions.
Simultaneous Assessment & Care:
Perform a cervical exam (if within your scope and indicated) to confirm dilation and station. Reassure her that the feeling of pressure is normal as the baby descends, but instruct her to pant or blow to avoid pushing until cervix is fully dilated.
Obtain vital signs (BP, Temp, Pulse, Resp) per unit protocol.
Establish IV access if not already present.
Provide emotional support and pain management options (e.g., encouragement, breathing techniques, or prepare for analgesia if requested and appropriate).
Evaluation & Communication: Continuously evaluate the EFM tracing. Report any non-reassuring signs immediately to the provider. Document all findings, interventions, and the patient's response.
Patient Safety and Precautions:
Key Point! Never leave a client in active labor with strong contractions unattended. Fetal status can change rapidly.
If variable or late decelerations occur, first-line interventions are: Turn mother to left lateral position, administer oxygen via non-rebreather mask at 10-15 L/min, increase IV fluids (if not contraindicated), and discontinue any labor-stimulating agents (e.g., Pitocin).
Monitor for signs of uterine hyperstimulation (contractions lasting >90 seconds or occurring more frequently than every 2 minutes without adequate rest).
Position the client comfortably, often semi-Fowler's or lateral.
Place the toco transducer on the fundus (top of uterus) where contractions are palpated strongest.
Use ultrasound gel and place the ultrasound transducer over the fetal back (usually found in the lower abdomen for vertex presentations) to obtain a clear heart rate signal.
Secure belts and adjust as needed. Ensure the tracing is clear on the monitor.
Interpret the tracing: Assess baseline rate, variability, presence of accelerations, and periodic changes (decelerations).
Medication Connection: If oxytocin (Pitocin) is being used for induction/augmentation and non-reassuring FHR patterns develop, the nurse must stop the oxytocin infusion to reduce uterine activity and improve placental blood flow.
A Word from Your Senior Nurse
"In the controlled chaos of a labor unit, your eyes should always flick to that monitor screen. That little blinking heart rate is your direct line to the baby's well-being. Prioritizing fetal monitoring isn't just a test answer—it's your first and most critical defense in safeguarding a new life. When you see strong, frequent contractions on the monitor, your brain should immediately link that to 'check the baby's response.' This clinical reasoning, connecting physiology to action, is what makes an excellent nurse and will absolutely be tested on your NCLEX. You've got this!"
Electronic Fetal Monitoring — The use of electronic devices to continuously record the fetal heart rate and uterine contractions, allowing for assessment of fetal well-being during labor.
Uteroplacental Insufficiency — A condition where blood flow through the placenta is reduced, compromising oxygen and nutrient transfer to the fetus. It is a primary cause of non-reassuring fetal heart rate patterns.
Late Decelerations — A type of periodic deceleration of the fetal heart rate that begins after the peak of a uterine contraction and reflects potential uteroplacental insufficiency and fetal hypoxia.
Active Phase of Labor — The phase of first-stage labor from approximately 6 cm of cervical dilation to full dilation (10 cm). It is characterized by more rapid dilation and stronger, more frequent contractions.
Fetal Station — A measurement of the descent of the fetal presenting part (usually the head) through the maternal pelvis relative to the ischial spines. It is measured in centimeters from -3 (above spines) to +3 (below spines).
