In a pesticide exposure scenario, which level of prevention involves recognizing early signs and initiating protective actions?

• A. Primary prevention
• B. Secondary prevention
• C. Tertiary prevention
• D. Quaternary prevention

Answer: (B)

Recognizing early signs of toxicity and taking protective actions is secondary prevention. This level focuses on catching problems early and stopping them from progressing, with prompt responses to early symptoms to prevent more serious illness or complications. In a pesticide exposure situation, noticing symptoms like irritation, dizziness, or nausea and quickly stopping exposure, decontaminating, and seeking care illustrates acting at an early stage to prevent further harm. Primary prevention would be preventing exposure in the first place (safety measures and PPE), while tertiary prevention addresses damage after it has occurred and aims to reduce long-term consequences. Quaternary prevention centers on avoiding unnecessary interventions.
