In planning primary prevention for tuberculosis in a school, which action is most appropriate for the nurse to take first?

• A. Getting permission from the principal to talk with students about TB risk factors
• B. Finding out how many students received the bacille Calmette-Guérin (BCG) vaccine
• C. Reading posters about TB symptoms from a district health bulletin
• D. Conducting TB skin tests for all students

Answer: (A)

Securing authorization from school leadership to engage students establishes the necessary support, permissions, and logistics to run a preventive education program in a school setting. This first step ensures you can access the student audience, align with school policies, and arrange appropriate time and resources before delivering any health messages about TB risk factors. Without this administrative buy-in, other actions—like checking vaccination records, passively reading posters, or conducting skin tests—either fail to address planning needs or fall into areas that are not primary prevention. Education about risk factors, delivered with proper approval and coordination, is the appropriate starting point for a school-based TB prevention effort.
