Her fasting blood glucose is 140 mg/dL and postprandial glucose is 180 mg/dL. What is the priority nursing intervention? Blood glucose monitoring and management in gestational diabetes ## 보기 1. Administer prescribed insulin and monitor blood glucose levels every 2 hours **✔ 정답** 2. Encourage increased physical activity and daily ambulation 3. Provide diabetic diet education and meal planning guidance 4. Schedule immediate consultation with endocrinologist **정답: 1** ## 해설 Immediate insulin administration with frequent monitoring is priority for poorly controlled GDM (fasting 140 mg/dL, postprandial 180 mg/dL). Other interventions (activity, education, consultation) are important but not immediate. ## 심화 해설 Understanding the Clinical Priority The client at 36 weeks gestation with gestational diabetes mellitus (GDM) presents with a fasting blood glucose of 140 mg/dL and a postprandial glucose of 180 mg/dL. These values significantly exceed the typical glycemic targets in pregnancy, indicating a failure of lifestyle modifications alone to achieve euglycemia. The pathophysiological basis of GDM involves pregnancy-induced insulin resistance, driven by placental hormones, coupled with inadequate pancreatic β-cell compensation to meet the increased metabolic demand . When β-cells cannot secrete sufficient insulin to overcome this resistance, maternal hyperglycemia ensues. Why Pharmacological Intervention is the Priority The priority nursing intervention is to administer prescribed insulin and monitor blood glucose levels every 2 hours. This is the correct action because persistent maternal hyperglycemia at this level poses an immediate and direct threat to both maternal and fetal well-being. The primary goal is rapid glycemic control to prevent acute complications. The rationale is rooted in the mechanism of action of insulin: it directly addresses the core defect of insufficient endogenous insulin to counteract the pregnancy-induced insulin resistance . Insulin therapy is the first-line pharmacological agent in GDM when medical nutrition therapy fails, as it does not cross the placenta in significant amounts, ensuring fetal safety while effectively lowering maternal blood glucose. Analysis of Incorrect Options - Option 2: Encourage increased physical activity and daily ambulation. While physical activity improves insulin sensitivity, it is an adjunctive, not a primary, intervention for a client with severely elevated glucose levels. At 36 weeks gestation with values of 140/180 mg/dL, lifestyle measures alone are insufficient and delaying pharmacological therapy increases the risk of fetal macrosomia, neonatal hypoglycemia, and preeclampsia. Safety must be established through glycemic control first. - Option 3: Provide diabetic diet education and meal planning guidance. Dietary counseling is a cornerstone of GDM management, but it is a foundational, long-term strategy. This client has already failed to achieve euglycemia, as evidenced by the current lab values. The immediate need is to correct the hyperglycemia with insulin; education can and should occur concurrently but does not take priority over a critical physiological intervention. - Option 4: Schedule immediate consultation with endocrinologist. While a multidisciplinary approach is valuable, the nurse's priority is to act on the prescribed orders. Waiting for a consultation creates a delay in treatment. The nurse is authorized and expected to administer the prescribed insulin and intensify monitoring, which is the direct action that will lower the dangerously high blood glucose levels. The role of continuous glucose monitoring (CGM) is an evolving diagnostic and management tool, but it does not replace the need for immediate therapeutic action when hyperglycemia is already confirmed . Clinical Integration and Monitoring Following insulin administration, frequent blood glucose monitoring every 2 hours is essential to evaluate the therapeutic response, detect hypoglycemia, and guide dose titration. This aligns with the principle that management of GDM requires a personalized approach to balance maternal euglycemia with fetal safety . The nurse must assess for signs of both hyperglycemia and hypoglycemia, as the goal is to normalize glucose levels without causing a dangerous drop. The integration of tele-nursing and enhanced self-efficacy strategies are valuable for long-term lifestyle adherence, but these are secondary to the immediate, nurse-driven pharmacological management of acute hyperglycemia in the inpatient setting . The immediate nursing action directly mitigates the pathophysiological driver of adverse outcomes by supplementing the insufficient endogenous insulin supply. ## 임상 시나리오 Clinical Priority in Gestational Diabetes A 36-week pregnant client with GDM has a fasting glucose of 140 mg/dL and postprandial glucose of 180 mg/dL. The immediate risk is fetal macrosomia, neonatal hypoglycemia, and stillbirth. Priority is rapid correction of maternal hyperglycemia. Nursing Intervention Guide - **Administer Insulin:** Give prescribed rapid-acting or regular insulin per sliding scale. Insulin does not cross the placenta and directly addresses the underlying insulin resistance. - **Frequent Monitoring:** Check blood glucose every 2 hours to assess response to insulin and prevent hypoglycemia. Target fasting ≤95 mg/dL and 1-hour postprandial ≤140 mg/dL. - **Fetal Surveillance:** Initiate continuous fetal monitoring to detect signs of distress related to hyperglycemia. Assess for fetal movement and heart rate variability. - **Patient Education:** Once stable, reinforce that insulin is temporary and necessary for fetal safety. Explain signs of hypo/hyperglycemia. Clinical Reasoning Lifestyle measures (diet, exercise) are foundational but insufficient for acute severe hyperglycemia. Delaying pharmacological intervention to consult an endocrinologist or provide education increases the risk of adverse outcomes. The nurse's priority is to execute the medical order that directly and immediately lowers blood glucose. ## 핵심 개념 - **Gestational Diabetes Mellitus (GDM)** — Glucose intolerance with onset or first recognition during pregnancy, caused by placental hormones increasing insulin resistance. - **Insulin Resistance** — A condition where cells fail to respond normally to insulin, requiring higher amounts of insulin to allow glucose to enter tissues. - **Euglycemia** — A state of normal blood glucose concentration, which is the therapeutic goal in managing diabetes. - **Postprandial Glucose** — Blood glucose level measured after a meal, typically targeted to be lower than 120-140 mg/dL in pregnancy. - **Beta-cell Compensation** — The ability of pancreatic beta cells to increase insulin secretion to overcome insulin resistance, which is inadequate in GDM. ## 같은 주제 문제 - [A nurse is assessing a pregnant client at 32 weeks gestation with gestational diabetes mel…](https://mymerci.kr/pages/nclex_q.php?qn_id=542866) - [A nurse is assessing a pregnant client at 36 weeks gestation with gestational diabetes mel…](https://mymerci.kr/pages/nclex_q.php?qn_id=542867) - [A pregnant client at 28 weeks gestation with gestational diabetes mellitus (GDM) comes to …](https://mymerci.kr/pages/nclex_q.php?qn_id=542868) - [A pregnant client at 24 weeks gestation with gestational diabetes mellitus is being taught…](https://mymerci.kr/pages/nclex_q.php?qn_id=542869) - [A pregnant client at 32 weeks gestation with gestational diabetes mellitus is admitted for…](https://mymerci.kr/pages/nclex_q.php?qn_id=542871) --- More free questions: [기출문제](https://mymerci.kr/) _학습 참고용입니다. 실제 임상은 최신 지침과 소속 기관 프로토콜을 따르세요._
