A 5-year-old child with Kawasaki disease is in the acute phase and has been hospitalized for 3 days. The child presents with high fever (102.8°F), bilateral conjunctival injection, strawberry tongue, and polymorphous rash. Which nursing action should be the highest priority at this time?

해설
Monitoring for coronary artery complications is the highest priority because Kawasaki disease can cause life-threatening aneurysms. Other options are supportive but do not address the most critical risk.

심화 해설

Core Nursing Explanation Key Concept Analysis: This question assesses the priority nursing action for a child in the acute phase of Kawasaki disease (Mucocutaneous Lymph Node Syndrome). The core pathophysiology is a systemic vasculitis that primarily affects medium-sized arteries, especially the coronary arteries. The acute phase (first 1-2 weeks) is characterized by intense inflammation and fever, and it is the period when coronary artery aneurysms can begin to develop. The highest priority is always the prevention or early detection of life-threatening complications.

Answer Rationale: Key Point! Option ③, "Monitor for signs of coronary artery complications," is the correct answer because it directly addresses the most serious and potentially fatal risk of Kawasaki disease. Coronary artery aneurysms can lead to myocardial infarction (MI), heart failure, or sudden death in children. Nursing vigilance for subtle signs like changes in vital signs (tachycardia, hypotension), chest pain, dyspnea, or signs of poor perfusion is critical. This monitoring is a continuous, proactive assessment that guides all other interventions.

Distractor Analysis:
Watch out for confusion! While managing fever (option ①) and preventing dehydration (option ②) are important supportive measures for patient comfort and stability, they are not the highest priority when weighed against the risk of a life-altering cardiac complication. These are comfort and maintenance interventions.
Option ④, applying cool compresses, is a comfort measure for the rash but is of the lowest priority. The rash in Kawasaki disease is not typically pruritic or dangerous; it is a diagnostic sign of the underlying vasculitis.

Related Concepts: The definitive treatment to reduce the risk of coronary artery complications is the administration of Intravenous Immunoglobulin (IVIG) and high-dose aspirin during the acute phase. Nursing care involves administering these medications safely and monitoring for effectiveness (resolution of fever) and adverse reactions. The nursing process dictates that assessment (for complications) always comes before intervention for comfort.

Concept Summary Kawasaki Disease Phases & Priorities:
1. Acute Phase (Days 1-11): High fever, classic symptoms (conjunctival injection, rash, strawberry tongue, extremity changes, cervical lymphadenopathy). Priority: Administer IVIG/Aspirin and monitor for cardiac complications.
2. Subacute Phase (Weeks 2-4): Fever resolves, but risk of coronary aneurysm peaks. Peeling of fingers/toes occurs. Priority: Continued cardiac monitoring, follow-up echocardiograms.
3. Convalescent Phase (Months 1-3+): Symptoms resolve, but children with aneurysms require long-term cardiology management.

Anatomy, Physiology & Pharmacology Points
  • Pathophysiology: Idiopathic vasculitis → inflammation of vessel walls (especially coronary arteries) → weakening of arterial wall → dilation/formation of aneurysm → risk of thrombosis, stenosis, or rupture.
  • Pharmacology: IVIG modulates the immune response to reduce inflammation. High-dose aspirin is used for its anti-inflammatory effect initially; later switched to low-dose for its antiplatelet effect to prevent clots in aneurysms.
  • Diagnostic Monitoring: Serial Echocardiograms are essential to detect and monitor coronary artery involvement.

Memory Tips
  • CRASH & Burn mnemonic for Kawasaki symptoms: Conjunctival injection, Rash, Adenopathy (cervical), Strawberry tongue, Hands & feet changes (edema/peeling). The "Burn" is the high fever. But remember, the real "burn" (danger) is to the HEART.
  • Priority Rule: In Kawasaki, think "Heart First." Any question about priority in the acute phase will almost always relate to cardiac monitoring or administering IVIG.

High-Frequency NCLEX Topics NCLEX loves to test the priority and complication monitoring for Kawasaki disease. You must know:
  1. The classic diagnostic criteria (fever + 4 of 5 other symptoms).
  2. That coronary artery aneurysms are the #1 concern.
  3. The treatment (IVIG + aspirin) and its purpose.
  4. That long-term aspirin therapy is for antiplatelet, not anti-inflammatory, effects in the convalescent phase.

Watch Out for Question Variations!
  • Symptom Identification: "A child has a high fever for 5 days, red eyes, a rash, and swollen hands. The nurse suspects..." (Answer: Kawasaki disease).
  • Medication Administration: "A child with Kawasaki disease is prescribed IVIG. Which finding indicates a therapeutic response?" (Answer: Resolution of fever within 24-36 hours).
  • Parent Education: "What is the most important information to give parents upon discharge?" (Answer: Importance of follow-up echocardiograms and watching for signs of heart problems).
  • Post-IVIG Care: "The nurse should monitor for which potential complication after IVIG infusion?" (Answer: Fluid overload, anaphylaxis).

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are the nurse caring for Liam, a 5-year-old admitted with Kawasaki disease. He is irritable, has a high fever, bright red eyes, a diffuse rash, and swollen, red palms and soles. He is scheduled for his first dose of IVIG.

Nursing Intervention Strategy:
  1. Assessment (Ongoing Priority): Before and after IVIG, perform focused cardiac assessments. Monitor heart rate and rhythm, blood pressure, respiratory rate, and oxygen saturation. Auscultate for murmurs or gallops. Assess for subtle signs of distress: irritability, pallor, diaphoresis, refusal to play, or complaints of "tummy ache" (young children may not verbalize chest pain). Document baseline and frequent neurovascular checks on extremities.
  2. Medication Administration & Monitoring: Administer IVIG as ordered, typically over 8-12 hours. Key Point! Use an infusion pump. Monitor closely for infusion reactions: fever, chills, headache, hypotension, nausea, or anaphylaxis (rare). Have emergency equipment and medications (e.g., diphenhydramine, epinephrine) available. Administer high-dose aspirin as ordered, with food/milk to prevent GI upset.
  3. Supportive Care: Provide acetaminophen for fever as ordered/needed. Encourage cool, soothing fluids (popsicles, water) to maintain hydration. Provide gentle mouth care for dry/strawberry tongue. Keep the skin clean and dry; avoid lotions or powders on the rash unless prescribed. Use soft linens and comfortable, loose clothing.
  4. Family Education & Psychosocial Support: Explain the disease process in simple terms, emphasizing that the treatment is aimed at protecting his heart. Teach parents to recognize warning signs to report: increased irritability, chest pain, difficulty breathing, or changes in color. Reassure them that the rash and peeling are normal parts of recovery.
Patient Safety and Precautions:
  • IVIG Precautions: Do not mix with other medications. Strict aseptic technique is vital. Monitor for fluid overload, especially in small children—assess for crackles, increased respiratory rate, and edema.
  • Aspirin & Reye's Syndrome: Educate parents that aspirin is used under strict medical supervision for this condition. They must avoid giving other over-the-counter products containing aspirin or salicylates. Inform them of the risk of Reye's syndrome (vomiting, confusion, lethargy) if the child gets chickenpox or influenza while on aspirin, and stress the importance of vaccination.
  • Infection Control: Kawasaki disease is not contagious, but the child may be immunocompromised. Practice good hand hygiene and protect from visitors with active infections.

Nursing Procedure & Medication Flow IVIG Administration (High-Alert Focus):
  1. Verify order, patient, and medication. Check for IgA deficiency history (risk of anaphylaxis).
  2. Obtain baseline vital signs, especially temperature.
  3. Start infusion slowly (e.g., 0.5-1 mL/kg/hr for first 30 min) as per protocol to observe for reaction.
  4. If tolerated, gradually increase rate to the ordered maintenance rate. Never exceed the recommended maximum rate.
  5. Monitor vital signs every 15-30 minutes initially, then hourly. Observe for entire infusion period.
  6. Post-infusion: Continue monitoring for delayed reactions for several hours.

A Word from Your Senior Nurse "Kawasaki disease is a classic example of where your nursing assessment skills are your most powerful tool. That fever and rash are obvious, but it's the silent ticking of the heart inflammation we're most worried about. In clinical practice, you become the detective, looking for the slightest clue—a faster pulse than yesterday, a bit more irritability, a dip in blood pressure. Your vigilant monitoring ensures that if a complication starts, it's caught early. For the NCLEX, remember this mantra: 'Kawasaki = Coronaries.' If the question is about priority, your mind should immediately go to the heart. This mindset saves lives on the floor and points on the test."
