A nurse is assisting with the admission of a 9-year-old child who has acute rheumatic fever. When obtaining the client's history, it is appropriate for the nurse to ask the parent which of the following questions?

A. Acute rheumatic fever often develops 2 to 6 weeks after an untreated or inadequately treated group A beta-hemolytic streptococcal pharyngitis (strep throat); asking about a recent sore throat is appropriate and relevant. B. Injuries are unrelated to the development of rheumatic fever. C. Rheumatic fever is an acquired condition, not a congenital defect, so this question is inappropriate. D. Isolation is not required for acute rheumatic fever since it is an inflammatory complication, not a contagious illness.
