Which nursing intervention is the priority in the preoperative period? ## 보기 1. Assess for signs of preterm labor and uterine contractions **✔ 정답** 2. Administer prophylactic antibiotics as ordered 3. Obtain informed consent from the client 4. Position the client in Trendelenburg position **정답: 1** ## 해설 Assessing for signs of preterm labor and uterine contractions is the priority because active labor is a contraindication to cervical cerclage. Other interventions are important but secondary to ensuring the procedure can be safely performed. ## 심화 해설 Understanding Cervical Incompetence and Cerclage At 20 weeks gestation, a diagnosis of cervical incompetence means the cervix is painlessly dilating and effacing without uterine contractions, which can lead to second-trimester loss or preterm birth. A cervical cerclage is a surgical procedure where a stitch is placed around the cervix to mechanically keep it closed. The preoperative priority is to ensure the client is a suitable candidate for surgery and that the procedure is not being performed in the presence of a contraindication, such as active preterm labor. Why Assessing for Preterm Labor Is the Priority The primary contraindication for placing a cervical cerclage is active preterm labor. If the client is having regular uterine contractions, the cerclage placement could stimulate further contractions, lead to rupture of membranes, or introduce infection into a uterus that is already preparing to expel the fetus. The foundational literature on cerclage, including the clinical trials referenced, operates on the premise that cerclage is indicated for mechanical cervical insufficiency, not for active labor. The studies exploring cerclage techniques and adjunctive therapies, such as the RCT comparing one-stitch versus two-stitch cerclage, explicitly enroll participants based on indications like a sonographic short cervix or physical exam findings in the absence of labor [1]. Similarly, research on anesthesia for cerclage placement and postoperative management with low-dose aspirin is built upon the assumption that the procedure was performed on a quiescent uterus [2,3]. Therefore, before any other intervention, the nurse must confirm the absence of preterm labor to prevent an iatrogenic complication and ensure the procedure’s foundational indication is met. Analyzing the Other Options While the other interventions are important components of perioperative care, they are not the immediate priority over a focused assessment that determines the safety of proceeding with the surgery. - Administer prophylactic antibiotics: Prophylactic antibiotics may be ordered to reduce the risk of postoperative infection, but this is a dependent nursing intervention that follows the provider's order and the confirmation that the surgery is appropriate. It does not take precedence over the initial assessment for a contraindication. - Obtain informed consent: Obtaining informed consent is a critical legal and ethical step before any surgical procedure. However, the surgeon is responsible for explaining the risks, benefits, and alternatives of the cerclage. The nurse's role is often to witness the signature and ensure the client's understanding. This step is typically performed after the decision for surgery is finalized, which depends on a negative assessment for preterm labor. - Position the client in Trendelenburg position: The Trendelenburg position, where the head is lower than the feet, is sometimes used preoperatively for a prolapsed cord or, in the context of cervical insufficiency, to use gravity to reduce prolapsed membranes back into the lower uterine segment. While it may be a preparatory intervention for an emergency cerclage with bulging membranes, it is not a universal priority for all scheduled cerclage patients and does not replace the fundamental assessment to rule out active labor . Clinical Reasoning and Test-Taking Strategy This question tests the application of the nursing process, where assessment always comes first. Before implementing any intervention, the nurse must collect and analyze data. In this specific clinical scenario, the most critical piece of data to gather is whether the client is experiencing uterine contractions, as this finding would directly contraindicate the planned procedure. The correct answer, assessing for signs of preterm labor, is the only option that represents a nursing assessment, making it the clear priority over the implementation-focused actions of administering medication, obtaining a signature, or positioning the client.References (research sources) - [1]Two-stitch versus one-stitch cervical cerclage in women with high risk for preterm birth: a stratified exploratory randomized controlled trial in China.RCT/clinical trialXu ZM, Zheng YJ, Yan WX, Jiang CH, Li HB, Zhang J, Pan M. (2026) · DOI: 10.1186/s12884-026-08809-8 ## 임상 시나리오 Clinical Guide: Preoperative Assessment for Cervical Cerclage A 20-week pregnant client with cervical incompetence is scheduled for cerclage. The nurse's priority is to ensure the procedure is safe to perform. The primary contraindication is active preterm labor, as placing the stitch in the presence of contractions can stimulate further labor, cause rupture of membranes, or introduce infection. Priority Nursing Assessment - Monitor for regular, painful uterine contractions. - Assess for low back pain, pelvic pressure, or vaginal discharge changes. - Evaluate fetal heart rate and activity. - Report any signs of labor immediately to the provider. Key Contraindications to Cerclage - Active preterm labor with progressive cervical change. - Rupture of membranes (confirmed or suspected). - Clinical signs of intra-amniotic infection (chorioamnionitis). - Fetal demise or major fetal anomaly incompatible with life. Nursing Actions Before Surgery - Verify informed consent is signed after provider discussion. - Administer preoperative medications (e.g., tocolytics, antibiotics) only after confirming absence of labor. - Position client supine with a left lateral tilt to avoid aortocaval compression, not routine Trendelenburg. - Provide emotional support and education about the procedure.
