The nurse caring for a toddler with Kawasaki disease who is receiving intravenous immunoglobulin for severe coronary inflammation is planning discharge teaching for the parents. Which instruction should the nurse provide during the discharge education?

Rationale: A. Plan for a follow-up echocardiogram occurring in 4 to 6 weeks: Follow-up echocardiograms are standard to monitor for coronary artery aneurysms, which may develop even after treatment. Early detection is vital to prevent long-term cardiac complications. B. Resume the toddler's normal immunization schedule: Live vaccines such as MMR and varicella should be delayed for at least 10 months after IVIG, as the therapy can interfere with vaccine efficacy. Non-live vaccines may proceed as scheduled. C. Irritability and tinnitus are expected for up to 2 weeks: Irritability is common, but tinnitus is not a recognized symptom of Kawasaki disease or its treatment. Persistent symptoms should be reported rather than assumed to be expected. D. Manage joint pain with a nonsteroidal antiinflammatory: Aspirin, not general NSAIDs, is typically used for inflammation and thrombosis prevention in Kawasaki disease. Use of other NSAIDs may interfere with aspirin’s antiplatelet effects.
