The nurse confirms premature rupture of membranes (PROM). Which nursing intervention should be the priority? ## 보기 1. Encourage ambulation to promote labor progression 2. Perform a sterile vaginal examination to assess cervical dilation 3. Position the client in bed rest with continuous fetal monitoring **✔ 정답** 4. Administer oxytocin to stimulate uterine contractions **정답: 3** ## 해설 With PROM at 34 weeks, bed rest with continuous fetal monitoring is priority to prevent cord prolapse and monitor fetal well-being. Ambulation (1) increases prolapse risk, sterile vaginal exam (2) may introduce infection, and oxytocin (4) is not indicated without labor. ## 심화 해설 Understanding the Clinical Scenario A client at 34 weeks gestation with confirmed premature rupture of membranes (PROM) presents a critical situation where the protective barrier between the fetus and the external environment has been lost. The immediate priority is to mitigate the risks that arise directly from this membrane breach, primarily infection and umbilical cord compression. Analysis of the Priority Intervention The correct action is to position the client on bed rest with continuous fetal monitoring. This choice addresses the two most urgent threats in PROM: - Infection Prevention: Once the chorioamniotic membranes rupture, the sterile intrauterine environment is exposed to ascending bacteria from the vagina. A key risk factor for developing chorioamnionitis is the performance of unnecessary vaginal examinations, which can introduce pathogens into the uterine cavity [1]. An evidence-based infection prevention bundle for PROM emphasizes limiting digital cervical checks to reduce this risk [1]. Bed rest and external monitoring are non-invasive strategies that avoid introducing bacteria, directly supporting infection control. - Fetal Well-being and Cord Compression: The loss of amniotic fluid removes the cushion that protects the umbilical cord. With ambulation or position changes, the risk of cord prolapse or compression increases, which can lead to variable decelerations and fetal hypoxia. Continuous electronic fetal monitoring allows for immediate detection of non-reassuring fetal heart rate patterns, such as those caused by cord compression, enabling rapid intervention [2]. Why the Other Options Are Incorrect - Option 1: Encourage ambulation to promote labor progression. Ambulation is contraindicated in PROM, especially before engagement of the presenting part, because gravity and movement significantly elevate the risk of an occult or overt umbilical cord prolapse, a life-threatening obstetric emergency for the fetus. The priority is to minimize this risk, not to promote labor. - Option 2: Perform a sterile vaginal examination to assess cervical dilation. While a speculum exam is essential for the initial diagnosis of PROM, a digital cervical examination should be avoided unless absolutely necessary and the patient is in active labor with an engaged presenting part. Each digital exam increases the risk of introducing vaginal flora into the amniotic cavity, which is a direct pathway to developing chorioamnionitis [1]. The pathophysiology of PROM is strongly linked to infectious and inflammatory processes that weaken the fetal membranes, and further introducing bacteria can exacerbate this, leading to serious maternal and neonatal morbidity [2, 4]. - Option 4: Administer oxytocin to stimulate uterine contractions. At 34 weeks gestation, the management goal for PROM is often expectant management to allow for fetal lung maturity, provided there are no signs of infection or fetal compromise. Immediate administration of oxytocin would be premature and inappropriate without a thorough assessment of fetal status, cervical readiness, and a decision for delivery. The immediate priority is to first establish fetal well-being and rule out cord compression, not to induce labor. ## 임상 시나리오 Clinical Guide: Premature Rupture of Membranes (PROM) at 34 Weeks **Immediate Priorities** - Initiate bed rest and continuous electronic fetal monitoring to assess for cord compression (variable decelerations) and fetal well-being. - Confirm membrane rupture via sterile speculum examination, pooling, ferning, or nitrazine test. **Do not perform a digital vaginal examination** unless the patient is in active labor or delivery is imminent, as this increases the risk of chorioamnionitis. **Infection Prevention Bundle** - Monitor maternal vital signs and fetal heart rate for signs of infection (maternal fever, fetal tachycardia). - Limit the number of vaginal examinations to the absolute minimum necessary. - Document the time of rupture, color, odor, and amount of fluid. **Management Considerations for Late Preterm (34-36 Weeks)** - Administer antenatal corticosteroids (betamethasone) if not previously given and no signs of infection, to accelerate fetal lung maturity. - Group B Streptococcus (GBS) prophylaxis is indicated per protocol if GBS status is positive or unknown. - Expectant management is generally recommended in the absence of infection or non-reassuring fetal status to allow for fetal maturation. ## 핵심 개념 - **Premature Rupture of Membranes** — Rupture of the amniotic membranes before labor begins, prior to 37 weeks of pregnancy. It is one of the main causes of preterm birth and carries risks of infection and umbilical cord complications. - **Cord Prolapse** — After the amniotic sac ruptures, the umbilical cord slips out through the vagina or cervix ahead of the baby's presenting part (head or buttocks). This is an emergency that causes acute fetal hypoxia due to cord compression. - **Continuous Fetal Monitoring** — Continuous recording of uterine contractions and fetal heart rate. It is essential for real-time assessment of fetal status in situations such as high-risk pregnancy or PROM. - **Chorioamnionitis** — Infection of the amniotic membrane and placenta. A serious complication that can occur after PROM, with signs including maternal fever, uterine tenderness, and foul-smelling vaginal discharge. - **Betamethasone / Corticosteroids** — A steroid medication given to promote fetal lung maturity when there is a risk of preterm birth. It is commonly used in pregnant women under 34 weeks with PROM. ## 같은 주제 문제 - [A pregnant client at 34 weeks gestation presents to the labor and delivery unit reporting …](https://mymerci.kr/pages/nclex_q.php?qn_id=543019) - [A 28-year-old gravida 1, para 0 client at 36 weeks gestation presents to the labor and del…](https://mymerci.kr/pages/nclex_q.php?qn_id=543020) - [A 32-year-old pregnant woman at 34 weeks gestation presents to the labor and delivery unit…](https://mymerci.kr/pages/nclex_q.php?qn_id=543021) - [A 25-year-old pregnant client at 32 weeks gestation presents to the labor and delivery uni…](https://mymerci.kr/pages/nclex_q.php?qn_id=543022) - [A pregnant client at 36 weeks gestation presents to the labor and delivery unit with a sud…](https://mymerci.kr/pages/nclex_q.php?qn_id=543024) - [A pregnant client at 34 weeks gestation presents to the labor and delivery unit with a sud…](https://mymerci.kr/pages/nclex_q.php?qn_id=543025) - [A pregnant woman at 36 weeks gestation presents to the labor and delivery unit with a sudd…](https://mymerci.kr/pages/nclex_q.php?qn_id=543026) --- More free questions: [기출문제](https://mymerci.kr/) _학습 참고용입니다. 실제 임상은 최신 지침과 소속 기관 프로토콜을 따르세요._
