The infant is exhibiting signs of neonatal abstinence syndrome (NAS). Which nursing intervention should be the priority? A 2-day-old newborn born to a mother with a history of cocaine use during pregnancy is displaying irritability, high-pitched crying, tremors, and difficulty feeding. The infant's vital signs show tachycardia and mild hypertension. ## 보기 1. Administer prescribed phenobarbital immediately to control seizures 2. Place the infant in a brightly lit nursery for continuous observation 3. Encourage frequent feeding every 2 hours to prevent hypoglycemia 4. Create a quiet, dimly lit environment and minimize stimulation **✔ 정답** **정답: 4** ## 해설 Creating a quiet, dimly lit environment minimizes stimulation, which is critical as overstimulation worsens NAS withdrawal symptoms. Phenobarbital is for seizures if present, bright lighting increases stimulation, and frequent feeding is supportive but not the priority. ## 심화 해설 Understanding Neonatal Abstinence Syndrome (NAS) and the Priority Intervention The correct answer is 4. Create a quiet, dimly lit environment and minimize stimulation. For a newborn exhibiting signs of neonatal abstinence syndrome (NAS), including irritability, high-pitched crying, tremors, and difficulty feeding, the foundational priority is to provide nonpharmacological supportive care that reduces environmental stressors. This approach directly addresses the neurobehavioral dysregulation caused by withdrawal. Why Nonpharmacological Support is the Priority The core pathophysiology of NAS involves a hyper-aroused and disorganized central nervous system. Infants exposed to substances like cocaine and alcohol in utero experience a sudden discontinuation at birth, leading to a hypernoradrenergic state. This manifests as the symptoms described: tachycardia, mild hypertension, tremors, and a high-pitched cry. The current evidence-based paradigm, as highlighted by the Eat, Sleep, Console (ESC) model, shifts the focus from scoring withdrawal symptoms to assessing an infant's functional ability to cope [1]. This model prioritizes nonpharmacologic interventions that support the infant's own capacity for self-regulation, with the environment being a critical modifiable factor. A quiet, dimly lit environment directly reduces sensory input to the already overloaded nervous system, helping to decrease irritability, conserve energy, and promote the organization necessary for successful feeding and sleep [1, 3]. Analysis of Incorrect Options - Option 1: Administer prescribed phenobarbital immediately to control seizures. While pharmacotherapy is a component of NAS management, it is not the first-line or priority intervention. The ESC model and scoping reviews emphasize that nonpharmacological interventions are the cornerstone of care and should be optimized before or alongside pharmacologic treatment [1, 3]. Phenobarbital is reserved for severe cases, particularly when seizures are present or when symptoms are not controlled by first-line agents like morphine. The scenario describes tremors, not confirmed seizure activity, making immediate pharmacotherapy a secondary, not primary, nursing action. The goal is to support the infant's function, not just suppress symptoms [1]. - Option 2: Place the infant in a brightly lit nursery for continuous observation. This action is contraindicated. A brightly lit, noisy environment provides excessive sensory stimulation, which will exacerbate the infant's central nervous system irritability and hyperactive reflexes [3, 4]. Continuous observation is necessary, but it must be performed in a setting that minimizes stress. The standard of care involves a calm, private room or a quiet corner of the nursery with dimmed lighting to promote neurobehavioral organization . - Option 3: Encourage frequent feeding every 2 hours to prevent hypoglycemia. Addressing feeding difficulties is a critical component of care, as described by the "Eat" in the ESC model [1]. However, the priority is to first create an environment where successful feeding is possible. An overstimulated, disorganized infant will have a poor suck-swallow-breathe coordination and will be unable to feed effectively regardless of how often feeding is offered. The immediate nursing intervention is to reduce stimulation to calm the infant, which then enables a more organized feeding experience. Furthermore, while hypoglycemia can be a concern with maternal polysubstance use, the primary driver of the feeding difficulty in this scenario is the NAS-induced neurobehavioral dysfunction. Evidence-Based Rationale for Environmental Management Systematic reviews of nonpharmacological interventions for NAS consistently identify environmental control as a key supportive measure. The traditional supportive interventions, which include minimizing stimulation from light and noise, are recommended based on expert consensus and descriptive studies as effective methods for reducing the severity of withdrawal symptoms . A scoping review of non-pharmacological care confirms that interventions like rooming-in in a quiet environment are effective strategies for managing NAS resulting from exposure to various drugs of abuse [3]. This approach aligns with the ESC model, which emphasizes the infant's ability to function and the crucial role of the parent-infant relationship in a supportive setting, rather than a stimulus-rich, assessment-focused environment [1]. By controlling the environment, the nurse helps the infant transition from a state of hyperarousal to one of calm alertness, which is a prerequisite for all other care activities, including feeding and bonding.References (research sources) - [1]Training and Integration of Eat, Sleep, Console Model for Infants and Families at an Urban Academic Health Center.Research articleConti S, Chin J, Kemble K, Witham BR, Yoder K, Pattison A, Zhang Y.

The Eat, Sleep, Console (ESC) model guides this approach, focusing on functional assessment over scoring. Create a quiet, dimly lit environment and minimize handling. Swaddle the infant, use gentle vertical rocking, and offer a pacifier for non-nutritive sucking to promote self-regulation and conserve energy. CautionA brightly lit, noisy nursery will worsen irritability and neurobehavioral dysregulation. Pharmacologic treatment like phenobarbital is reserved for severe cases unresponsive to environmental and supportive measures, or for seizure control. ## 핵심 개념 - **Neonatal Abstinence Syndrome** — Neonatal abstinence syndrome. A group of withdrawal symptoms experienced by a newborn after birth, following the mother's use of addictive substances such as opioids, cocaine, or benzodiazepines during pregnancy. Symptoms include irritability, high-pitched crying, tremors, feeding difficulties, tachycardia, respiratory distress, sweating, and diarrhea. - **Cocaine** — Central nervous system stimulant. It excessively activates the nervous system by blocking the reuptake of dopamine, norepinephrine, and serotonin. It crosses the placenta and affects the fetus, and after birth, withdrawal can cause hyperexcitability and symptoms related to vasoconstriction (hypertension). - **Environmental Modification** — Environmental modification. Primary non-pharmacological intervention for NAS management. Aims to reduce sensory overload in newborns by dimming lights, minimizing noise, using swaddling, and reducing unnecessary handling. - **High-Pitched Cry** — High-pitched cry. A sign that can appear in neonatal neurological disorders or hyperexcitability states (e.g., brain injury, infection, NAS, metabolic abnormalities). In NAS, it is a representative symptom of central nervous system hyperstimulation. - **Finnegan Scoring System** — The most widely used tool for objectively assessing the severity of NAS symptoms. It scores 21 items, including neurological, metabolic, respiratory, and gastrointestinal symptoms. A score above a certain threshold serves as the criterion for initiating pharmacological treatment. ## 같은 주제 문제 - [A nurse is assessing a 3-day-old newborn whose mother has a history of opioid use during p…](https://mymerci.kr/pages/nclex_q.php?qn_id=543299) - [A nurse is assessing a 1-day-old newborn whose mother has a history of polysubstance abuse…](https://mymerci.kr/pages/nclex_q.php?qn_id=543300) - [A nurse is assessing a newborn whose mother has a history of substance abuse during pregna…](https://mymerci.kr/pages/nclex_q.php?qn_id=543301) - [A nurse is caring for a newborn diagnosed with neonatal abstinence syndrome (NAS) whose mo…](https://mymerci.kr/pages/nclex_q.php?qn_id=543302) - [A nurse is caring for a newborn who was born to a mother with a history of opioid addictio…](https://mymerci.kr/pages/nclex_q.php?qn_id=543303) --- More free questions: [기출문제](https://mymerci.kr/) _학습 참고용입니다. 실제 임상은 최신 지침과 소속 기관 프로토콜을 따르세요._
