A premature infant born at 30 weeks gestation is being monitored in the NICU. The nurse notices the infant has developed abdominal distention, bilious vomiting, and bloody stools. The infant appears lethargic and has temperature instability. Which nursing action should be the priority?
1Increase the frequency of feedings to maintain nutrition
2Discontinue enteral feedings immediately and notify the physician✓ 정답
3Administer probiotics to restore normal gut flora
4Position the infant prone to reduce abdominal pressure
해설
Immediate cessation of enteral feedings is critical when NEC is suspected to prevent intestinal damage and perforation. Other interventions like probiotics or positioning are not initial priorities.
Core Nursing ExplanationKey Concept Analysis: This question assesses the priority nursing action for a premature infant with signs suspicious for Necrotizing Enterocolitis (NEC). NEC is a severe gastrointestinal emergency primarily affecting premature infants, characterized by inflammation and necrosis of the intestinal wall. The classic triad of symptoms includes abdominal distention, bilious vomiting, and bloody stools. Lethargy and temperature instability are systemic signs of sepsis, indicating the condition may be progressing. The pathophysiology involves intestinal ischemia, bacterial invasion, and an inflammatory response that can lead to perforation, peritonitis, and death.
Answer Rationale: Key Point! The absolute priority in suspected NEC is to "rest the gut." Continuing enteral feedings provides substrate for bacterial overgrowth, increases intestinal gas production, and places mechanical stress on the potentially necrotic bowel, dramatically increasing the risk of perforation. Therefore, the nurse must discontinue all enteral feedings immediately and notify the physician/provider to initiate diagnostic workup (e.g., abdominal X-rays for pneumatosis intestinalis) and medical management (IV antibiotics, NPO, possible surgery).
Distractor Analysis:
Option 1 (Increase feedings): This is contraindicated and dangerous. Feeding exacerbates the disease process and can lead to catastrophic bowel perforation.
Option 3 (Administer probiotics): While probiotics may have a role in NEC prevention in some protocols, they are not a treatment for active, suspected NEC. The priority is to stop the ongoing injury, not to modify flora.
Option 4 (Position prone): Although prone positioning may improve oxygenation and comfort, it does not address the root cause of the problem. More critically, in an unstable infant with abdominal distention, careful positioning is needed, but it is not the immediate life-saving intervention.
Related Concepts: The nursing process dictates that the first step is assessment, but when assessment reveals a potential life-threatening complication, the nurse must move immediately to a protective intervention (stopping the harmful stimulus) and communication (notifying the provider). This scenario tests the ABCs with a neonatal focus—airway and breathing are implied in monitoring, but circulation and perfusion are threatened by sepsis and potential hypovolemia from third-spacing in the gut. Maintaining NPO (nothing by mouth) status and initiating IV fluids/antibiotics are the cornerstone medical management steps that follow the nurse's critical action.
Concept Summary
Concept
Key Points
Necrotizing Enterocolitis (NEC)
Gut emergency in preemies. Sx: Abdominal distention, bilious emesis, bloody stools, lethargy, temp instability.
Diagnostic Sign: Pneumatosis intestinalis (gas in bowel wall) on abdominal X-ray is a hallmark.
Pharmacology: Broad-spectrum IV antibiotics (e.g., Ampicillin and Gentamicin) are started empirically to cover gut flora and prevent sepsis.
Memory Tips
Acronym for NEC Sx: Abdomen distended, Bilious vomit, Bloody stool = ABB (like a warning sign).
Rule of NPO: "When in doubt (about NEC), feedings go out!" The gut must rest.
High-Frequency NCLEX Topics
NCLEX loves testing priority actions for unstable patients. NEC is a classic pediatric/neonatal emergency. Remember: Assessment leads to action. The action here is protective (stop the cause of harm) and communicative (notify the team). This combines safe patient care and the nurse's role within the healthcare team.
Watch Out for Question Variations!
Shift from Symptom to Intervention: "The nurse identifies pneumatosis intestinalis on an X-ray. Which order should the nurse anticipate?" (Answer: NPO, IV antibiotics, NG tube).
Shift to Prevention: "Which intervention is most effective in preventing NEC in preterm infants?" (Answer: Providing human breast milk, cautious advancement of feedings).
Shift to Post-op Care: "An infant returns from surgery for NEC. What is the priority assessment?" (Answer: Assess abdominal incision/drainage, bowel sounds, vital signs for sepsis).
Nursing Clinical Practice GuideClinical Scenario: You are the NICU nurse for Baby Boy Lee, born at 30 weeks, currently on day 10 of life. He has been advancing on fortified breast milk feeds via an orogastric (OG) tube. During your assessment, his abdomen is visibly rounded and firm to palpation (previously soft), his residual gastric aspirate is bilious, and you note a small amount of bright red blood in his stool. He is less active than usual and his axillary temperature is 36.0°C (96.8°F).
Nursing Intervention Strategy:
Immediate Action (Priority): Stop the current enteral feeding immediately. Clamp the OG tube. Do not restart feeds without a specific order.
Notification & Communication: Call the neonatal nurse practitioner or attending physician immediately. Use SBAR (Situation, Background, Assessment, Recommendation) format: "Situation: I'm calling about Baby Lee with suspected NEC. Background: 30-week preemie on feeds. Assessment: New abdominal distention, bilious aspirate, bloody stool, lethargy, temp instability. Recommendation: I have stopped feeds. Would you like me to obtain an abdominal X-ray and start IV access?"
Assessment & Monitoring:
Vital Signs: Monitor heart rate (for bradycardia/tachycardia), respiratory status (for apnea), and temperature frequently (every 1-2 hours initially).
Abdominal Assessment: Measure abdominal girth at the umbilicus every 4-8 hours, mark the area. Listen for bowel sounds (may be absent). Note any discoloration (red/purple) of the abdominal wall, a late sign of perforation.
Gastrointestinal: Connect the OG tube to low intermittent suction as ordered to decompress the stomach. Measure and characterize all output (emesis, stool, OG drainage).
Supportive Care:
IV Access & Fluids: Ensure patent IV access for administration of fluids, antibiotics, and parenteral nutrition (TPN - Total Parenteral Nutrition).
Lab Work: Prepare for labs (CBC, electrolytes, blood culture).
Comfort & Positioning: Handle the infant gently. Position on side or supine per unit policy (prone may be contraindicated for close observation). Provide non-nutritive sucking with a pacifier for comfort if condition allows.
Patient Safety and Precautions:
Contraindication: Absolutely NO enteral feedings until NEC is ruled out or resolved, which may take 7-14 days or longer.
Medication Caution: Antibiotics like gentamicin require monitoring of peak and trough levels to avoid nephrotoxicity and ototoxicity.
Key Monitoring Points: Watch for signs of perforation and sepsis: sudden deterioration, increased abdominal distention, rigid abdomen, respiratory distress, hypotension, and worsening lethargy.
Nursing Procedure & Medication FlowProcedure: Managing an Infant with Suspected NEC
1. Recognize signs (ABB: Abdominal distention, Bilious emesis, Bloody stool).
2. STOP the feeding. Document time stopped.
3. Notify provider STAT using SBAR.
4. Obtain order for and assist with abdominal X-ray (left lateral decubitus view is often ordered).
5. Place OG/NG tube to low intermittent suction as ordered.
6. Obtain IV access if not present. Start IV fluids as ordered.
7. Administer IV antibiotics as ordered (e.g., ampicillin 50 mg/kg IV q12h, gentamicin 4 mg/kg IV q24h). Verify dose carefully based on current weight.
8. Monitor strictly: I&O (Intake & Output), abdominal girth, vital signs, labs.
9. Provide family support and education about the condition and plan.
A Word from Your Senior Nurse: "In the NICU, your eyes and hands are the first line of defense. A subtle change in abdominal firmness or a single episode of bilious vomiting in a preemie should set off alarm bells for NEC. Never hesitate to stop feeds and call the team. It's always better to be cautious and have a false alarm than to miss the early signs of this devastating disease. When you study, don't just memorize 'stop feeds'—understand *why*. You're giving that fragile intestine a chance to heal and potentially saving a life. That's the power of knowledgeable, vigilant nursing."
Necrotizing Enterocolitis — A life-threatening gastrointestinal disease primarily affecting premature infants, characterized by inflammation and necrosis of the intestinal mucosa, potentially leading to perforation and sepsis.
Pneumatosis Intestinalis — A radiographic sign pathognomonic for NEC, appearing as gas bubbles within the bowel wall, indicating necrosis.
NPO (Nil Per Os) — Latin for "nothing by mouth." A critical medical order to rest the gastrointestinal tract, which is the priority intervention for suspected NEC.
Bilious Vomiting — Vomitus that is greenish-yellow due to the presence of bile. In a newborn, especially a preemie, this is a red flag for intestinal obstruction or NEC.
SBAR Communication — A structured method (Situation, Background, Assessment, Recommendation) for communicating critical information, essential when notifying a provider about a deteriorating patient like an infant with suspected NEC.
