Which action by the school nurse is important in the prevention of rheumatic fever?
- A. Encourage routine cholesterol screenings.
- B. Conduct routine blood pressure screenings.
- C. Refer children with sore throats for throat cultures.
- D. Recommend salicylates instead of acetaminophen for minor discomforts.
Correct Answer: C
Rationale: Nurses have a role in prevention—primarily in screening school-age children for sore throats caused by group A β-hemolytic streptococci. They can achieve this by actively participating in throat culture screening or by referring children with possible streptococcal sore throats for testing. Cholesterol and blood pressure screenings do not facilitate the recognition and treatment of group A β-hemolytic streptococci. Salicylates should be avoided routinely because of the risk of Reye syndrome after viral illnesses.
