A 3-year-old child has been hospitalized for 6 days with Kawasaki disease. The child has received high-dose aspirin and intravenous immunoglobulin (IVIG). Which assessment finding would be the nurse's highest priority to report immediately to the healthcare provider?
1Temperature of 101.2°F (38.4°C) with irritability
2Bilateral conjunctival injection without purulent discharge
3Peeling skin on the fingertips and toes
4New onset of chest pain with shortness of breath✓ 정답
해설
Chest pain with shortness of breath in Kawasaki disease indicates potential cardiac complications like coronary artery aneurysms or myocardial infarction, which are life-threatening and require immediate intervention. Other findings (fever, conjunctival injection, peeling skin) are expected in acute phase and managed with standard care.
Core Nursing ExplanationKey Concept Analysis: This question tests the critical ability to prioritize nursing assessments in a patient with Kawasaki disease (KD), specifically focusing on identifying life-threatening complications. The core pathophysiology involves systemic vasculitis, which can lead to inflammation and damage of the coronary arteries, resulting in coronary artery aneurysms. The highest priority in nursing is always the patient's ABCs (Airway, Breathing, Circulation). While KD has many characteristic symptoms, the development of cardiac complications is the most dangerous sequela.
Answer Rationale: Key Point! Option ④, "New onset of chest pain with shortness of breath," is the highest priority because it directly signals potential, immediate cardiac compromise. In a child with KD, this could indicate myocardial ischemia, infarction, pericarditis, or rupture of a coronary aneurysm—all medical emergencies. This finding requires immediate reporting to the healthcare provider for urgent evaluation (e.g., ECG, echocardiogram, cardiac enzymes).
Distractor Analysis:
Watch out for confusion! Option ①: A temperature of 101.2°F (38.4°C) with irritability is common in the acute phase of KD, even after initial IVIG treatment, as fever can persist or recur. While it needs monitoring and may require a second dose of IVIG, it is not an immediate life-threatening sign like cardiac symptoms.
Option ②: Bilateral conjunctival injection (non-purulent) is a classic diagnostic criterion for KD ("bulbar conjunctival injection") and is expected during the illness. It is not a complication but a symptom of the acute inflammatory phase.
Option ③: Peeling skin on the fingertips and toes (desquamation) is a characteristic finding of the subacute phase of KD, typically occurring 2-3 weeks after fever onset. It is an expected part of the disease course and not an urgent complication.
Related Concepts: The primary goal of treatment with IVIG (Intravenous Immunoglobulin) and high-dose aspirin is to reduce inflammation and prevent coronary artery damage. Nursing care involves vigilant monitoring for both the expected symptoms of the disease phases and the signs of the dreaded complication: coronary artery involvement.
May indicate IVIG resistance or ongoing inflammation.
Moderate Priority. Report to provider for possible second-line treatment, but not an immediate emergency.
Conjunctival Injection, Peeling Skin
Diagnostic criteria and expected disease course symptoms.
Low Priority for urgent reporting. Document as part of ongoing assessment.
Anatomy, Physiology & Pharmacology Points
Pathophysiology: KD causes inflammation of medium-sized arteries, especially the coronary arteries. The inflamed vessel wall can weaken and balloon out, forming an aneurysm, which can thrombose or rupture.
IVIG Mechanism: Modulates the immune response, reduces systemic inflammation, and has been proven to significantly decrease the incidence of coronary artery aneurysms when given early.
Aspirin Dosing:Key Point! High-dose aspirin (anti-inflammatory dose) is used in the acute phase. After fever resolves, it is switched to low-dose aspirin (antiplatelet dose) to prevent thrombosis in damaged coronary arteries.
Memory Tips
CRASH & Burn (for KD symptoms): Conjunctivitis, Rash, Adenopathy (cervical lymph nodes), Strawberry tongue, Hands/feet (edema/erythema later peeling). And the "Burn" is the high fever.
Priority Rule: In any pediatric condition, but especially KD, think "Chest Pain = Cardiac Alarm." It trumps all other expected symptoms.
High-Frequency NCLEX Topics
NCLEX loves to test priority-setting and complication recognition. Kawasaki disease is a classic topic for this. You must know:
1. The classic symptoms for diagnosis (fever + 4 of 5 other criteria).
2. The purpose of IVIG and aspirin therapy.
3. Most importantly: That coronary artery aneurysms are the #1 complication, and signs like chest pain, shortness of breath, or palpitations require immediate action.
Watch Out for Question Variations!
Instead of "highest priority to report," it could ask: "The nurse should prepare for which diagnostic test first?" → Answer: Electrocardiogram (ECG/EKG) or Echocardiogram.
It could ask about patient education for discharge: "The mother asks when the aspirin dose will be changed." → Answer: When the fever subsides and acute inflammation is controlled, it is switched from high-dose to low-dose for its antiplatelet effect.
It could test on Watch out for confusion!Contraindications for live vaccines (like MMR, Varicella) after IVIG administration (typically an 11-month delay).
Nursing Clinical Practice GuideClinical Scenario: You are caring for Leo, a 3-year-old boy on day 6 of hospitalization for Kawasaki disease. He received IVIG 48 hours ago and is on high-dose aspirin. His fever initially broke but he has been irritable today. During your afternoon assessment, he points to his chest and says "owie," and his respiratory rate has increased from 24 to 36 breaths per minute.
Nursing Intervention Strategy:
Immediate Assessment (ABCs):
Airway & Breathing: Assess work of breathing (retractions, nasal flaring), auscultate lung sounds, apply pulse oximeter. Administer oxygen if SpO2 < 95%.
Circulation: Obtain full set of vital signs. Check heart rate and rhythm, assess peripheral pulses, capillary refill, and skin color.
Focused Cardiac Assessment: Ask about pain quality (sharp, pressure). Palpate for heaves or thrills. Auscultate heart sounds for murmurs, rubs, or gallops (signs of myocarditis or pericarditis).
Immediate Action: Stay with the child. Call the rapid response team or the healthcare provider immediately using SBAR (Situation, Background, Assessment, Recommendation) communication. Example: "Situation: 3-year-old with Kawasaki disease reporting new chest pain and tachypnea. Background: Day 6 of illness, received IVIG 2 days ago. Assessment: Chest pain verbalized, RR 36, SpO2 96% on room air, heart rate 140. Recommendation: I need you to assess him now and I am preparing for an ECG."
Prepare for Diagnostics/Interventions: Have the crash cart accessible. Obtain a 12-lead ECG. Ensure IV access is patent. Prepare for possible transfer to a higher level of care (e.g., Pediatric ICU).
Patient Safety and Precautions:
Aspirin & Reye's Syndrome: Educate parents that aspirin is used under strict medical supervision for KD. They must never give over-the-counter aspirin or other salicylates for fever once at home unless specifically instructed, due to the risk of Reye's syndrome (a severe liver and brain condition).
IVIG Infusion Reactions: Monitor closely during infusion for fever, chills, headache, hypotension, or anaphylaxis. Infuse per protocol (often starting slow and increasing rate as tolerated).
Dose: 80-100 mg/kg/day in 4 divided doses during acute phase.
Monitoring: Watch for signs of salicylism (tinnitus, hyperventilation, nausea). Monitor liver function tests and for signs of bleeding.
Transition: After patient is afebrile for 48-72 hours, the dose is typically reduced to 3-5 mg/kg/day (antiplatelet dose) for 6-8 weeks or longer if aneurysms are present.
IVIG Administration:
Dose: 2 g/kg as a single infusion over 10-12 hours.
Pre-medication: Often pre-medicate with acetaminophen and diphenhydramine to prevent infusion-related reactions.
Rate: Start slow (e.g., 0.5 mL/kg/hr), gradually increase as tolerated to the ordered maintenance rate. Never exceed the maximum rate per facility policy.
A Word from Your Senior Nurse
"Kawasaki disease is one of those pediatric conditions where your nursing vigilance literally saves hearts. The fever and rash are dramatic, but the real enemy is silent—hiding in the coronary arteries. Your most critical tool is not the medication pump, but your skilled assessment. When a toddler, who can barely describe pain, shows you they are in distress, you must be their advocate and detective. On the NCLEX, they are testing if you understand that principle: expected symptoms are managed, but new signs of cardiorespiratory compromise are an all-hands-on-deck emergency. Carry that mindset to the bedside, and you'll be an outstanding nurse."
Kawasaki Disease — An acute systemic vasculitis of unknown etiology, primarily affecting medium-sized arteries (especially coronary arteries) in young children, characterized by fever and specific clinical criteria.
Coronary Artery Aneurysm — A localized dilation or ballooning of a coronary artery wall, a serious complication of Kawasaki disease that can lead to thrombosis, myocardial infarction, or rupture.
IVIG (Intravenous Immunoglobulin) — A blood product containing pooled antibodies used as the primary treatment in Kawasaki disease to reduce systemic inflammation and significantly lower the risk of coronary artery complications.
High-Dose Aspirin — In Kawasaki disease, aspirin is given in anti-inflammatory doses (80-100 mg/kg/day) during the acute febrile phase to reduce fever and inflammation.
Desquamation — The peeling of skin, particularly from the fingertips and toes, which is a characteristic finding in the subacute phase of Kawasaki disease, typically occurring 2-3 weeks after fever onset.
