A nurse is assessing a primigravida client at 38 weeks gestation who is in active labor. Which assessment finding would indicate that the client is progressing normally through the first stage of labor?

해설
Active labor involves regular, strong contractions every 3-5 minutes lasting 45-60 seconds. Option 3 matches this pattern, indicating normal progress. Other options show early labor or abnormal findings.

Core Nursing Explanation Key Concept Analysis: This question assesses your ability to identify the normal characteristics of Active labor, which is part of the First stage of labor. The first stage is divided into three phases: Latent, Active, and Transition. The key to answering this question is recognizing the contraction pattern, cervical dilation, and effacement that define the active phase.

Answer Rationale: Key Point! For a primigravida at 38 weeks, normal progression into active labor is characterized by regular, frequent, and strong contractions along with significant cervical change. Option ③ describes contractions every 3-4 minutes, lasting 45-60 seconds, with moderate to strong intensity. This pattern is the classic hallmark of the active phase, where cervical dilation typically progresses from about 6 cm to 10 cm. This indicates effective labor and normal progression.

Distractor Analysis:
Watch out for confusion! Option ① describes contractions every 8-10 minutes lasting 30 seconds. This pattern is characteristic of Early or Latent labor, not active labor. The contractions are too infrequent, too short, and of mild intensity.
Watch out for confusion! Option ② describes a cervix that is 2 cm dilated and 25% effaced. This is also a finding of Latent labor. While it's a normal finding for that early phase, it does not indicate progression into the active phase of the first stage.
Watch out for confusion! Option ④ presents a Fetal Heart Rate (FHR) baseline of 110 bpm (the lower limit of normal is 110-160 bpm) with Late decelerations. Late decelerations are a non-reassuring fetal status indicating possible uteroplacental insufficiency. This is an abnormal finding requiring intervention, not an indicator of normal labor progress.

Related Concepts: Understanding the stages and phases of labor is fundamental. The first stage ends with full cervical dilation (10 cm). The second stage is from full dilation to delivery of the baby. The third stage is from delivery of the baby to delivery of the placenta. Nursing assessments must continuously monitor both maternal progress (contractions, cervix) and fetal well-being (FHR patterns). Concept Summary

Anatomy, Physiology & Pharmacology PointsPhysiology: Effective labor contractions involve a fundal dominance pattern—starting at the top (fundus) of the uterus and spreading downward—which is most efficient for cervical dilation and fetal descent. • Pharmacology: Oxytocin (Pitocin) is a drug used to augment labor. It must be titrated carefully to achieve a contraction pattern similar to normal active labor (q2-3 min, lasting

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are the nurse in Labor & Delivery. Maria, a 25-year-old primigravida at 39 weeks, is admitted. She reports contractions that started 6 hours ago and are now "very strong and coming fast." She is anxious and having difficulty coping with the pain.

Nursing Intervention Strategy: 1. Assessment: Perform a focused assessment. Time her contractions: they are every 3 minutes, lasting 55 seconds, palpated as strong. Check the electronic fetal monitor: FHR baseline 140 bpm with accelerations, no decelerations. A vaginal exam by the provider reveals cervix is 7 cm dilated, 90% effaced, and the fetus is at -1 station. Key Point! This confirms she is in the Active phase of labor. 2. Nursing Diagnosis & Planning: Acute pain related to uterine contractions and tissue dilation. The plan is to provide non-pharmacological and pharmacological pain relief and continuous support. 3. Implementation: • Provide continuous emotional support and encouragement. • Assist with breathing techniques (e.g., patterned-paced breathing). • Offer position changes (e.g., upright, side-lying, hands-and-knees) to promote comfort and fetal descent. • Administer prescribed analgesia (e.g., IV opioids) or prepare for epidural anesthesia if requested. • Continue continuous electronic fetal monitoring (EFM) or intermittent auscultation per protocol. 4. Evaluation: Reassess pain level, contraction pattern, and FHR every 15-30 minutes. Evaluate cervical progress in 1-2 hours to ensure labor is advancing.

Patient Safety and Precautions: • Never leave a patient in active labor unattended for prolonged periods. • Be vigilant for signs of non-reassuring fetal status (e.g., late or variable decelerations, bradycardia, minimal variability). • Monitor for signs of maternal exhaustion or dehydration. Nursing Procedure & Medication Flow Procedure: Assisting with Epidural Anesthesia 1. Pre-procedure: Ensure informed consent is obtained. Establish a large-bore IV line and administer a preload of IV fluids (e.g., 500-1000 mL Lactated Ringer's) to prevent hypotension. 2. During procedure: Assist the anesthesiologist by positioning the patient (sitting or lateral) and providing support. Monitor maternal BP every 2-5 minutes after the test dose and initial bolus. 3. Post-procedure: Monitor for complications: Maternal hypotension (treat with position change, IV fluids, and possibly ephedrine), Urinary retention (may require catheterization), and Pruritus (itching, treat with diphenhydramine if ordered). A Word from Your Senior Nurse "Labor is a dynamic process, and your role as the nurse is to be the calm, knowledgeable guide. Recognizing the shift from latent to active labor is crucial because it changes everything—the patient's needs, the frequency of monitoring, and the urgency of pain management options. On the NCLEX, they love to test if you can distinguish 'normal progress' from 'needs intervention.' In real life, that skill is how you keep both mom and baby safe. Always tie your knowledge back to the two patients you're caring for: the birthing person and the fetus."
