单选题 The nurse is preparing to discharge a child who has rheumatic fever. Which of the following medications is prescribed to prevent recurrence of rheumatic fever?
A. Glucocorticoids.
B. Digoxin.
C. Antibiotics.
D. Anti-inflammatory medications.

【正确答案】 C

【答案解析】Because the child with rheumatic fever is at risk for a recurrence, especially if the condition is complicated by carditis, long-term antibiotic therapy is necessary into adulthood, maybe even for life. Digoxin may be prescribed to treat heart failure, but it doesn't prevent the recurrence of rheumatic fever. Corticosteroids and anti-inflammatory medications reduce inflammation in rheumatic fever but won't prevent a recurrence.
