Core Nursing Explanation
Key Concept Analysis: This question tests the priority nursing intervention for an infant with
gastroschisis immediately after birth. Gastroschisis is a congenital defect where the infant's intestines (and sometimes other organs) protrude through a defect in the abdominal wall, usually to the right of the umbilicus. The exposed bowel is
not covered by a protective sac (unlike omphalocele), making it highly vulnerable to
fluid loss, heat loss, trauma, and infection. The pathophysiological priority is to protect the exposed viscera and prevent hypothermia and dehydration, which are immediate life threats.
Answer Rationale:
Key Point! The correct answer is to cover the exposed bowel with warm, moist sterile saline dressings and plastic wrap. This intervention directly addresses the
ABCs (Airway, Breathing, Circulation) of neonatal resuscitation and stabilization, specifically addressing "C" for circulation/volume status. Moist dressings prevent the bowel from drying out and becoming necrotic. The saline should be warmed to prevent hypothermia. The plastic wrap (e.g., sterile bowel bag) provides an occlusive layer that further minimizes fluid and heat loss and protects from contamination. This is the
immediate, life-preserving action before any other care.
Distractor Analysis:
Watch out for confusion! Option ②, placing the infant supine, is incorrect. A supine position can cause tension, kinking, or compromised blood flow to the exposed bowel. The preferred position is on the
side or with the bowel supported in a way that avoids pressure.
Option ③, beginning immediate oral feeding, is contraindicated and dangerous. The infant will require
NPO (Nothing by mouth) status and placement of an
orogastric (OG) or nasogastric (NG) tube for decompression to prevent abdominal distension and further compromise of the bowel. Hypoglycemia is a concern but is managed with
IV fluids (Intravenous fluids), not oral feeds.
Option ④, administering prophylactic antibiotics, is an important intervention but is
not the highest priority. Physical protection of the bowel from contamination comes first. Antibiotics are typically given but follow the initial stabilization and protective measures.
Related Concepts: It is crucial to differentiate gastroschisis from
omphalocele. In omphalocele, the organs are contained within a sac, which offers some protection. However, the initial nursing priority for both defects still involves protecting the exposed mass, preventing heat/fluid loss, and avoiding pressure. Always remember the nursing process:
Assessment (of the defect and infant's stability) leads to the priority Intervention (protection) before Planning for surgery.
Concept Summary
| Condition | Definition & Key Feature | Immediate Nursing Priority |
| Gastroschisis | Abdominal wall defect, usually right of umbilicus. NO protective sac. Bowel is exposed. | 1. Cover with warm, moist sterile saline dressings & plastic wrap. 2. Prevent heat/fluid loss. 3. Position to avoid tension on bowel. 4. NPO, OG/NG decompression. |
| Omphalocele | Abdominal wall defect at umbilicus. Organs are contained within a sac (peritoneum & amnion). | 1. Protect sac from rupture (moist dressings). 2. Similar precautions for heat/fluid loss. 3. Often associated with other anomalies (e.g., cardiac, genetic). |
Side-by-Side Comparison!
| Feature | Gastroschisis | Omphalocele |
| Sac | Absent | Present |
| Location | Usually to the right of the umbilicus | At the umbilicus (midline) |
| Contents | Usually intestines only (may be inflamed) | Intestines, liver, other organs |
| Associated Anomalies | Less common (mainly intestinal atresia) | Very common (cardiac, genetic like Trisomy 13/18) |
| Initial Covering | Warm, moist sterile dressings + plastic wrap (critical) | Moist dressings to keep sac intact |
Anatomy, Physiology & Pharmacology Points
Pathophysiology: The exposed bowel in gastroschisis loses fluid through evaporation, leading to
hypovolemia and electrolyte imbalances. It also loses heat rapidly, causing
hypothermia. The lack of a sac makes it prone to infection and mechanical injury.
Pharmacology: Broad-spectrum IV antibiotics (e.g., ampicillin, gentamicin) are started to prevent sepsis but are secondary to physical protection. IV fluids with dextrose (e.g., D10W) are initiated to maintain hydration and prevent hypoglycemia.

Side-lying position (Not supine)
High-Frequency NCLEX Topics
NCLEX loves testing priority-setting in neonatal emergencies. Gastroschisis/omphalocele questions often test: 1) The first nursing action, 2) Differentiation between the two defects, and 3) Understanding of contraindications (like oral feeding). Remember: Airway, Breathing, Circulation, and Defect Protection guide your priorities.
Watch Out for Question Variations!
* Instead of "highest priority," the question may ask: "The nurse prepares which equipment first?" (Answer: Sterile saline dressings and plastic wrap/bowel bag).
* The question could present a scenario where the bowel is dry: "The nurse notes the exposed bowel appears dry. Which action should the nurse take?" (Answer: Apply sterile saline-soaked dressings immediately).
* It might combine with other neonatal issues: "A newborn with gastroschisis has a temperature of 36.0°C (96.8°F). Which action should the nurse take first?" (The first action is still to ensure the bowel is covered with warm dressings, then use a radiant warmer).
