A nurse is assessing a newborn with gastroschisis. Which assessment finding would be most concerning and require immediate intervention?
1Bowel loops appear pink and moist with active peristalsis
2Newborn demonstrates strong sucking reflex during feeding attempts
3Urine output measures 2 mL/kg/hr over the past 4 hours
4Bowel loops appear dusky with decreased peristaltic activity✓ 정답
해설
Dusky bowel loops with decreased peristalsis indicate compromised perfusion and potential necrosis, requiring immediate surgical intervention in gastroschisis. Other findings (pink bowel, strong sucking reflex, adequate urine output) are normal or expected and do not necessitate urgent action.

Core Nursing ExplanationKey Concept Analysis: This question assesses the critical nursing assessment for a newborn with Gastroschisis, a congenital abdominal wall defect where the intestines protrude outside the body, Key Point! without a protective sac. The primary complication is intestinal ischemia and necrosis due to direct exposure, vascular compromise, and potential volvulus (twisting) of the exposed bowel. The nurse's priority is to assess the viability of the exposed bowel.
Answer Rationale: Option ④ is correct because it describes signs of impaired perfusion and impending bowel necrosis. "Dusky" color indicates cyanosis and poor oxygenation, and "decreased peristaltic activity" suggests the bowel muscle is becoming ischemic and non-functional. This is a surgical emergency requiring immediate intervention to prevent bowel loss, sepsis, and death.
Distractor Analysis:
• Watch out for confusion! Option ① describes healthy, viable bowel. Pink, moist bowel with active peristalsis is the desired finding and indicates good perfusion. This is a normal assessment, not a concern.
• Option ②, a strong sucking reflex, is a positive neurological and nutritional sign. While feeding is typically withheld until after surgical repair, a good reflex is not a concern.
• Option ③, urine output of 2 mL/kg/hr, is within the normal range for a newborn (1-2 mL/kg/hr). It indicates adequate renal perfusion and hydration status, which is supportive but not the primary focus for the exposed bowel.
Related Concepts: The immediate care for gastroschisis focuses on protecting the exposed viscera. The bowel is covered with a sterile, saline-soaked dressing and the baby is positioned to avoid tension on the mesentery. IV fluids are started to prevent dehydration and third-spacing. The definitive treatment is surgical reduction of the bowel and closure of the defect. This condition is distinct from Omphalocele, where organs are contained within a sac.
임상 시나리오
Nursing Clinical Practice GuideClinical Scenario: You are the nurse in the Neonatal Intensive Care Unit (NICU) receiving a term newborn diagnosed with gastroschisis via prenatal ultrasound. The baby is placed under a radiant warmer. You note a defect to the right of the umbilicus with loops of intestine exposed.
Nursing Intervention Strategy:
1. Assessment: Immediately assess the exposed bowel for color (pink vs. dusky/black), moisture, presence of peristalsis, and integrity. Monitor for signs of infection. Assess vital signs, especially for hypothermia (common due to evaporative heat loss).
2. Immediate Care:
• Place the newborn in a lateral position or support the bowel to prevent kinking.
• Cover the exposed bowel with a sterile, non-adherent dressing (e.g., petrolatum gauze) soaked in warm, sterile saline. Cover this with plastic wrap or a sterile bowel bag to minimize fluid and heat loss. Key Point! Never use dry gauze directly on the bowel, as it can cause desiccation and adhesion.
• Insert a nasogastric (NG) or orogastric (OG) tube to low intermittent suction to decompress the stomach and prevent further bowel distension.
• Start IV access for fluid resuscitation (often 1.5-2 times maintenance) to replace massive third-space losses.
3. Patient Safety and Precautions: Maintain strict aseptic technique. Monitor closely for signs of sepsis (temperature instability, tachycardia, lethargy). Avoid placing the baby supine, which can put pressure on the mesenteric blood supply.
Nursing Procedure & Medication FlowPre-Operative Management:
• Fluids: Administer isotonic IV fluids (e.g., Normal Saline, Lactated Ringer's) with dextrose. Anticipate high fluid requirements.
• Antibiotics: Broad-spectrum IV antibiotics (e.g., Ampicillin and Gentamicin) are typically started prophylactically due to high infection risk.
• Thermoregulation: Use a radiant warmer and monitor temperature hourly. Goal: maintain normothermia.
A Word from Your Senior Nurse
"With gastroschisis, your eyes and hands are your best assessment tools for that exposed bowel. Think of it like a plant – it needs to stay pink, moist, and wiggling (peristalsis) to be healthy. The moment it starts looking dusky, purple, or still, you sound the alarm. This isn't just a 'dressing change'; you are literally preserving organ function. Your vigilant assessment and meticulous protective care in those first critical hours directly impact this baby's surgical outcome and long-term health. In the NICU, we don't just monitor – we actively defend."
핵심 개념
Gastroschisis — A congenital abdominal wall defect where the intestines (and sometimes other organs) protrude through a defect, typically to the RIGHT of the umbilicus, WITHOUT a protective sac.
Omphalocele — A congenital abdominal wall defect where organs protrude through the umbilicus, covered by a protective peritoneal sac. Often associated with other genetic syndromes.
Peristalsis — The coordinated, wave-like muscular contractions of the gastrointestinal tract that move contents forward. Its presence indicates viable, functional bowel.
Bowel Necrosis — Death of intestinal tissue due to lack of blood supply (ischemia). In gastroschisis, it is a feared complication from vascular compromise or volvulus of the exposed bowel.
Third-Spacing — The shift of fluid from the intravascular space into interstitial spaces or body cavities. In gastroschisis, massive fluid loss occurs from the exposed, inflamed bowel surface, leading to hypovolemia.
Concept Summary
• Primary Problem: Exposed bowel → Risk of ischemia, necrosis, infection, fluid/heat loss.
• Nursing Priority: Assess bowel viability (Color, Moisture, Peristalsis).
• Immediate Action for Dusky Bowel: Notify surgeon immediately; it's a surgical emergency.
• Key Pre-op Care: Protect bowel (saline dressings), decompress stomach (NG tube), resuscitate fluids (IV), prevent hypothermia, give antibiotics.
