A nurse is planning care for a 10-year-old child who has rubeola. Which of the following interventions should the nurse plan to include?

Rubeola (measles) is a highly contagious viral respiratory infection caused by the measles virus, characterized by fever, cough, coryza, conjunctivitis, and a maculopapular rash. It spreads through airborne transmission and requires strict infection control measures to prevent outbreaks. Management is primarily supportive, with a strong emphasis on isolation to limit transmission during the infectious period. Nursing care focuses on symptom relief, monitoring for complications, and enforcing appropriate precautions. Rationale: A. Administering antiviral medication is not a standard treatment for rubeola because it is a viral illness that is primarily managed with supportive care. There is no routinely recommended specific antiviral therapy for uncomplicated measles. Treatment focuses on hydration, fever control, and prevention of complications such as pneumonia or encephalitis. B. Providing humidified oxygen may be necessary only if the child develops respiratory complications such as severe pneumonia or hypoxia. However, it is not a routine intervention for all children with rubeola. Most cases are managed with supportive respiratory care unless significant respiratory distress is present. C. Placing the child in a cool bath is not appropriate because it does not address the underlying infection and may increase discomfort or chills. Fever management in rubeola is achieved using antipyretics and maintaining a comfortable environment rather than aggressive cooling methods. Care should prioritize comfort and infection control rather than temperature shock. D. Isolation until the fifth day of the rash is essential because rubeola is highly contagious from four days before to four days after rash onset. Maintaining airborne precautions and isolating the child during this period helps prevent transmission to others. This intervention is critical in controlling the spread of infection within healthcare and community settings.
