Stage 5 — Take action. The child is afebrile 24 hours after IVIG and is receiving aspirin. The LAD coronary Z-score was 2.7. The nurse prepares discharge teaching for the caregiver. Classify each situation the caregiver might report after discharge by the response the nurse should teach.

Quick answer
Expected: fingertip peeling, a nosebleed that stops with pressure, inactivated flu shot. Same day: fever 38.4 C, sibling with influenza, refusing aspirin with only ibuprofen at home. Emergency: sudden pallor, sweating, and inconsolable crying; hard to wake with fast breathing and mottled legs.

Why this is correct
Each situation is sorted by the specific risk it creates for a child with a small coronary aneurysm on aspirin. Periungual desquamation is a normal subacute finding. Aspirin causes minor bleeding, which is concerning only if it does not stop. Fever after discharge may mean recrudescent disease that needs evaluation today. Influenza exposure raises Reye syndrome risk, and ibuprofen blocks aspirin's antiplatelet effect, so both need a same-day prescriber decision. In young children, myocardial ischemia presents as pallor, diaphoresis, irritability, and inconsolable crying rather than chest pain.

Easy analogy or mental picture
Sort like a triage desk: things that are part of the healing script, things that change the medication plan today, and things that mean the heart is in trouble right now.

Memory hook
Toddler heart attack = pale, sweaty, screaming, not chest pain.

NCLEX decision rule
For discharge teaching after Kawasaki disease, link each report to aneurysm risk, aspirin safety, or treatment failure, and choose the urgency from that link rather than from how alarming the finding looks.

Why the other choices are wrong
Peeling skin and a nosebleed look alarming to caregivers and are often over-triaged, but they are expected and self-limited here. The inactivated flu shot is tempting to classify as a problem because live vaccines are delayed after IVIG, but inactivated influenza vaccine is recommended for children on aspirin. Fever at home is tempting to send to emergency services, but in a hemodynamically stable child it needs same-day evaluation, not an ambulance. The sibling's influenza and the ibuprofen substitution look minor but change the safety of the aspirin plan. Pallor with sweating and inconsolable crying is easy to dismiss as a tantrum, which is why it is the key emergency cue.
