A pregnant client at 34 weeks gestation presents to the labor and delivery unit with a sudden gush of clear fluid from the vagina 2 hours ago. The nurse's initial assessment reveals a fetal heart rate of 110-120 bpm with occasional variable decelerations, maternal temperature of 99.2°F (37.3°C), and the client reports feeling decreased fetal movement. What is the nurse's priority action?

The priority is a sterile speculum exam to confirm PROM and assess for cord prolapse, as variable decelerations suggest cord compression. Other actions (antibiotics, cesarean, positioning) may be needed later but are not the immediate priority.

Core Nursing Explanation Key Concept Analysis: This question tests the priority nursing action for a patient with suspected Premature Rupture of Membranes (PROM) at 34 weeks gestation, presenting with concerning signs like variable decelerations and decreased fetal movement. The core principle is the ABCs (Airway, Breathing, Circulation) with a fetal focus. In obstetrics, the fetus is the "second patient," and the priority is to assess for immediate, life-threatening complications like umbilical cord prolapse or occult cord compression, which can lead to fetal hypoxia and death.

Answer Rationale: The correct answer is to perform a Key Point! sterile speculum examination. This is the priority because it serves two critical, immediate purposes: 1) Confirming the diagnosis of rupture of membranes (ROM) by visualizing pooling of amniotic fluid in the vaginal vault, and 2) Ruling out the emergency of umbilical cord prolapse. Variable decelerations on the fetal heart rate (FHR) tracing are a classic sign of cord compression. A sterile speculum exam allows the nurse or provider to visually confirm if the cord has descended into the vagina, which would necessitate an immediate, emergent intervention. This action is the essential first step in the nursing process (Assessment) to gather data for all subsequent decisions.

Distractor Analysis:
Watch out for confusion! Option ② (Administer antibiotics) is an important intervention for PROM to prevent chorioamnionitis, but it is not the immediate priority. Infection prevention is crucial but secondary to assessing for an acute, life-threatening fetal complication.
Option ③ (Prepare for immediate cesarean) is a potential action but is premature. The decision for a cesarean delivery depends on the findings of the initial assessment (e.g., confirmed cord prolapse, non-reassuring fetal status, gestational age). Jumping to this step without assessment is incorrect.
Option ④ (Trendelenburg position and oxygen) is an appropriate intervention for suspected or confirmed cord prolapse to relieve pressure on the cord. However, applying this intervention before confirming the presence of a prolapsed cord via a sterile exam is putting the cart before the horse. The assessment must guide the specific intervention.

Related Concepts: This scenario integrates knowledge of intrapartum fetal monitoring (interpreting variable decelerations), complications of PROM (infection, cord prolapse, preterm labor), and the systematic approach to obstetric emergencies (assess first, then intervene based on findings).

Premature Rupture of Membranes (PROM)

Rupture of amniotic sac before onset of labor. At 임상 시나리오 Nursing Clinical Practice Guide Clinical Scenario: You are the nurse in triage. Ms. Lopez, 34 weeks pregnant, states, "My water broke at home, and the baby hasn't been moving as much." You apply the external fetal monitor and see a baseline of 115 with variable decelerations down to 80 bpm with some contractions. Nursing Intervention Strategy: Immediate Action & Assessment: Explain the procedure to the client. With assistance, perform a sterile speculum examination. Observe for pooling of clear fluid. Visually inspect the cervical os and vaginal canal for any pulsating or non-pulsating cord. Do not perform a digital cervical exam if PROM is confirmed or suspected, as it increases infection risk and could disrupt a potentially prolapsed cord. If Cord is NOT Prolapsed: Confirm ROM with Nitrazine/ferning if needed. Continue continuous electronic fetal monitoring (EFM). Monitor maternal vital signs, especially temperature (infection sign). Notify the provider. Administer antibiotics and corticosteroids as per protocol and order. If Cord IS Prolapsed (OB Emergency): Immediately call for help (provider, anesthesia, OR team). Manually elevate the fetal presenting part off the cord using a gloved hand in the vagina (if trained) or apply firm pressure suprapubically. Place the mother in Trendelenburg or knee-chest position. Administer oxygen via non-rebreather mask at 10-15 L/min. Prepare for emergency cesarean delivery. Patient Safety and Precautions: Contraindication: Avoid digital cervical exams until active labor is established or delivery is imminent, to reduce infection risk in PROM. Monitoring: Watch for signs of chorioamnionitis: maternal fever > 100.4°F (38°C), fetal tachycardia, uterine tenderness, foul-smelling amniotic fluid. Documentation: Precisely document the time of ROM, color/odor/amount of fluid, FHR pattern, assessment findings, all actions taken, and provider notifications. Nursing Procedure & Medication Flow Procedure: Assisting with/Performing Sterile Speculum Exam for Suspected ROM 1. Gather equipment: Sterile speculum, sterile gloves, light source, sterile lubricant (water-soluble), Nitrazine paper, microscope slide. 2. Position patient in dorsal lithotomy with proper draping. 3. Don sterile gloves. Gently insert lubricated speculum to visualize cervix. 4. Observe for fluid pooling in posterior vaginal fornix. 5. If fluid is present, use sterile cotton swab to collect sample for Nitrazine test (turns blue with alkaline amniotic fluid) and ferning test. 6. Before removing speculum, carefully inspect for cord or fetal parts. Medication: Antibiotic Administration for PPROM - Common regimen: Ampicillin 2g IV load, then 1g IV q6h. Often combined with Erythromycin. - Purpose: Prolong pregnancy and reduce neonatal morbidity (infection, IVH, NEC). - Nursing Role: Administer on time, monitor for allergic reaction, educate patient on purpose. A Word from Your Senior Nurse "In the fast-paced world of L&D, your ability to stay calm and systematic is everything. This scenario is classic: your brain might scream 'Do something!' but the most professional action is often to gather critical information first. That sterile speculum exam is your best tool. It tells you if you're dealing with a straightforward PROM or a true 'all-hands-on-deck' emergency. Remember, you are the eyes and hands for the provider until they arrive. Your accurate assessment sets the entire team's response in motion. On the NCLEX and at the bedside, never underestimate the power of a good, thorough assessment!" 마이메르시로 국가고시 완벽 대비 기출문제와 상세 해설을 무료로. 내 약점을 분석하고 진도를 관리하며 더 똑똑하게 공부하세요. 무료로 시작하기 App Store Google Play 학습 참고용입니다. 실제 임상은 최신 지침과 소속 기관 프로토콜을 따르세요.
