## 문제

A nurse is assessing a newborn with gastroschisis. Which assessment finding would be most concerning and require immediate intervention?

## 보기

1. Bowel loops appear pink and moist with active peristalsis
2. Newborn demonstrates strong sucking reflex during feeding attempts
3. Urine output measures 2 mL/kg/hr over the past 4 hours
4. Bowel loops appear dusky with decreased peristaltic activity **✔ 정답**

**정답: 4**

## 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.

Understanding the Priority: Tissue Perfusion in Gastroschisis

In the context of NCLEX-RN prioritization, assessment findings that indicate a threat to tissue viability or organ perfusion always demand immediate intervention. For a newborn with gastroschisis, the exposed bowel is vulnerable to vascular compromise. The most concerning finding is a change in the color and motility of the herniated bowel loops, as this signals a progression from healthy tissue to ischemic injury.

Analysis of Assessment Findings

A dusky appearance with decreased peristaltic activity is a classic sign of bowel ischemia or necrosis. In gastroschisis, the eviscerated intestine is susceptible to mesenteric blood flow obstruction, which can occur due to volvulus, constriction at the fascial defect, or insensible fluid loss leading to hypoperfusion [1,4]. This finding represents a surgical emergency because irreversible tissue damage occurs rapidly. The pathophysiology involves compromised arterial inflow or venous outflow, leading to cellular hypoxia, loss of smooth muscle function (decreased peristalsis), and a characteristic dark or dusky color change.

The other options represent expected or non-emergent findings:

- Pink, moist bowel loops with active peristalsis indicate healthy, well-perfused tissue. This is the baseline appearance that should be maintained by protecting the exposed organs with a sterile, saline-soaked dressing and preventing mechanical obstruction .

- A strong sucking reflex is a normal neurological finding in a newborn. In the preoperative phase of gastroschisis management, the newborn is kept NPO (nothing by mouth) with nasogastric decompression, so the presence of the reflex itself does not require an intervention beyond maintaining the ordered NPO status .

- A urine output of 2 mL/kg/hr is a normal finding, indicating adequate renal perfusion and fluid balance. While fluid resuscitation is critical in gastroschisis due to third-spacing losses from the exposed viscera, this specific value does not signal a need for immediate intervention beyond ongoing monitoring .

Clinical Application of the ERNICA Guideline

The European reference network (ERNICA) guideline emphasizes that management of gastroschisis focuses on preventing injury to the exposed bowel and minimizing insensible fluid loss . The guideline’s systematic review supports that outcomes depend heavily on the condition of the bowel at birth and the prevention of secondary ischemic insults. A finding of dusky, hypoperistaltic bowel directly contradicts the goal of preserving bowel viability and indicates that the protective interventions (such as proper positioning of the infant to prevent kinking of the mesentery or maintaining a protective covering) may have failed, or a new mechanical obstruction has developed [1,4]. This necessitates an immediate escalation to the surgical team for possible emergency exploration, as the window for salvaging ischemic bowel is extremely narrow .

Gastroschisis: Recognizing Bowel IschemiaPrioritizing Assessment Findings in the Exposed Abdominal Contents
The exposed bowel in gastroschisis is at high risk for vascular compromise. The most critical assessment finding is a change from pink and moist to dusky or darkened color, coupled with decreased peristaltic activity. This indicates bowel ischemia, a surgical emergency where mesenteric blood flow is obstructed.

Immediate nursing action is required to prevent irreversible necrosis. The defect should be covered with a sterile, saline-soaked, non-adherent dressing and then wrapped with plastic to minimize heat and fluid loss. The infant is placed NPO, and an orogastric tube is inserted for decompression. Continuous monitoring of the bowel's color and perfusion is essential.

CautionDo not confuse normal post-birth changes with ischemia. A healthy bowel is pink and moist. A dusky, matted, or dull appearance is a late sign of compromise. Any report of this finding requires an immediate call to the surgical team.

## 핵심 개념

- **Gastroschisis** — A congenital abdominal wall defect where the bowel herniates outside the body without a protective sac, leaving it exposed to amniotic fluid and air.
- **Bowel Ischemia** — A condition of reduced blood flow to the intestines, leading to tissue hypoxia, cellular damage, and if prolonged, necrosis.
- **Peristalsis** — The involuntary, wave-like contractions of smooth muscle in the gastrointestinal tract that propel contents forward; its decrease suggests loss of function.
