A 12-month-old infant with confirmed intussusception is scheduled for a barium enema reduction procedure. The infant has been experiencing intermittent severe abdominal pain, vomiting, and has passed one stool containing blood and mucus. Which nursing intervention should be the priority?

The nurse is caring for a 9-month-old infant with confirmed intussusception who is scheduled for a barium enema reduction procedure.

Maintaining NPO status is the priority for an infant with intussusception to prevent aspiration and prepare for potential emergency surgery if non-surgical reduction fails. Other interventions like pain medication or oral fluids are contraindicated in this acute setting.

Core Nursing Explanation Key Concept Analysis: This question tests the priority nursing intervention for an infant with intussusception scheduled for a barium enema reduction. Intussusception is a pediatric surgical emergency where one segment of the intestine telescopes into another, causing obstruction, ischemia, and the classic "currant jelly" stool. The priority is always airway, breathing, and circulation (ABCs), but in the context of a planned procedure, preparation for potential complications and surgery is paramount.

Answer Rationale: Key Point! The correct answer is to Maintain NPO status and prepare for potential surgical intervention. Here's why:
1. NPO (Nothing by Mouth): The infant is scheduled for a procedure that may require sedation or anesthesia. Maintaining NPO status is critical to prevent aspiration of gastric contents. Furthermore, if the non-surgical reduction (barium enema) fails or causes a perforation, the infant will need immediate surgery. Being NPO is a mandatory preoperative preparation.
2. Prepare for Surgery: The barium enema is a therapeutic diagnostic procedure. It is not always successful. The nurse must anticipate and prepare for the next step—surgery—which is a common outcome. Preparation includes ensuring IV access, completing preoperative checklists, and educating the family.

Distractor Analysis:
• Watch out for confusion! Option 1 (Administer pain medication): While pain management is important, administering analgesics, especially opioids, can mask the progression of symptoms (like pain) which are critical assessment findings. It can also depress respirations, complicating potential sedation for the procedure. Pain relief often comes after diagnosis and a management plan is set.
• Watch out for confusion! Option 2 (Encourage oral fluids): This is contraindicated. The infant is vomiting and has a potential intestinal obstruction. Giving oral fluids can worsen vomiting, increase the risk of aspiration, and is not allowed when NPO for a procedure.
• Watch out for confusion! Option 3 (Apply warm compresses): This is inappropriate and potentially dangerous. Applying heat to an inflamed or ischemic abdomen can increase edema and potentially accelerate tissue damage. It does not address the underlying mechanical obstruction.

Related Concepts: The nursing priorities for intussusception revolve around the nursing process: Assessment (vital signs, pain, stool characteristics, abdominal distension), Preparation (NPO, IV fluids for hydration, pre-procedure care), and Monitoring for complications (perforation, signs of shock). Concept Summary • Intussusception: Telescoping of the intestine causing obstruction. A pediatric emergency.
• Classic Triad: Intermittent severe abdominal pain, vomiting, and "currant jelly" stools (blood and mucus).
• Barium Enema: Both diagnostic and potentially therapeutic (hydrostatic reduction).
• Nursing Priority: Maintain NPO, establish IV access, monitor for deterioration, prepare for surgery.

ConditionKey FeaturePriority Nursing Intervention
IntussusceptionTelescoping bowel, "currant jelly" stool, surgical emergencyMaintain NPO, prepare for procedure/surgery, monitor for shock
Pyloric StenosisProjectile non-bilious vomiting, olive-shaped mass, metabolic alkalosisMaintain NPO, correct fluid/electrolyte imbalance pre-op
AppendicitisPeriumbilical pain migrating to RLQ, rebound tenderness, feverMaintain NPO, administer IV antibiotics, prepare for appendectomy
Anatomy, Physiology & Pharmacology Points • Pathophysiology: The proximal intestine (intussusceptum) invaginates into the distal segment (intussuscipiens). This leads to venous congestion, edema, ischemia, and eventually necrosis and perforation if not reduced.
• Barium/ Air Enema Mechanism: The pressure from the instilled contrast or air pushes the telescoped segment back into place, reducing the intussusception.
• Contraindication for Enema: Signs of peritonitis or perforation (rigid abdomen, severe distension, shock).
Memory Tips • Acronym for Symptoms: Pain (intermittent, severe), Vomiting, Currant jelly stool.
• Think "NPO & OR": For any acute abdominal condition with planned intervention, the mantra is NPO (Nothing by Mouth) and Prepare for the OR (Operating Room).
High-Frequency NCLEX Topics NCLEX loves to test priority-setting and contraindications. Intussusception is a classic pediatric GI disorder. You must know why giving fluids or pain meds is wrong in the acute pre-procedural phase. The correct answer often involves safety (preventing aspiration) and preparation for the next step (surgery).
Watch Out for Question Variations! • Instead of asking for the priority intervention, the question might ask: "Which finding indicates a successful barium enema reduction?" (Answer: Passage of barium into the small intestine, resolution of pain, passage of normal stool).
• Or: "What is the nurse's priority assessment after the barium enema procedure?" (Answer: Monitor for return of bowel function, assess for signs of perforation - fever, increased abdominal pain, rigidity).

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are the nurse in the Pediatric Emergency Department. A frantic mother brings in her 9-month-old son. She reports he has been drawing his legs up and crying intensely every 15-20 minutes for the past 6 hours, is vomiting, and just had a diaper with red, jelly-like stool. The pediatrician suspects intussusception and orders a STAT barium enema.

Nursing Intervention Strategy:
1. Immediate Assessment (ABCs): Check airway, breathing, circulation. Assess vital signs, noting tachycardia (early sign of shock), and palpate abdomen for a possible sausage-shaped mass in the RUQ.
2. Priority Action: Place the infant NPO. Insert an IV line (if not already present) for hydration and medication access. Administer IV fluids (e.g., Normal Saline) to correct or prevent dehydration.
3. Pre-Procedure Care: Explain the procedure to the parents. Ensure informed consent is signed. Assist the radiology team. Have emergency equipment (suction, oxygen) available at the bedside.
4. Post-Procedure Monitoring: After the enema, monitor closely for 24 hours for recurrence (symptoms returning). Advance diet per protocol (usually clear liquids first) once bowel sounds return and the infant shows no signs of distress.

Patient Safety and Precautions:
• Never give enemas, laxatives, or feed the infant until the obstruction is ruled out or resolved.
• Monitor for Perforation: Sudden worsening of pain, abdominal distension, rigid abdomen, fever, and signs of shock (tachycardia, hypotension) indicate perforation—a surgical emergency.
Nursing Procedure & Medication Flow Procedure: Preparing for Barium Enema Reduction
1. Verify NPO status (typically 4-6 hours for solids/formula).
2. Establish a reliable IV line.
3. Administer IV fluids to maintain hydration (e.g., D5 1/2 NS).
4. Assist with positioning the infant in the Radiology department.
5. During the procedure, monitor the infant's vital signs and comfort.
6. After the procedure, monitor for passage of barium and stool.

Medication Caution: Sedatives or analgesics are typically withheld until a diagnosis is confirmed and a plan is in place, as they can alter the clinical picture. A Word from Your Senior Nurse "In pediatrics, a crying infant with an acute abdomen is one of the most stressful scenarios. Your calm, systematic approach is everything. Remember, with intussusception, time is bowel. Your priority actions—NPO, IV access, and preparing for the worst-case scenario (surgery)—are what keep that baby safe. On the NCLEX, they are testing your ability to see past the immediate distress (the crying, the parent's anxiety) to the underlying life-threatening process and the necessary medical pathway. Think: 'What does this patient need to be ready for next?' That's the key to priority questions."
