Which of the following is a potential symptom of pesticide poisoning?

Severe headaches and nausea are recognized symptoms of pesticide poisoning. Pesticides can disrupt the normal functioning of the body's systems, leading to a variety of acute and chronic health effects. Headaches are a common neurological response to toxic substances, while nausea can indicate gastrointestinal distress resulting from exposure to harmful chemicals. Such symptoms are critical indicators that someone may be experiencing pesticide poisoning, and they warrant immediate medical attention to mitigate further complications.

In contrast, increased appetite, improved mental clarity, and enhanced physical strength are not associated with pesticide poisoning. These symptoms suggest positive health benefits or improvements, which do not align with the negative health impacts of pesticide exposure. Therefore, recognizing severe headaches and nausea as potential symptoms is vital for people working in environments where pesticides are used and for those involved in pesticide safety and management practices.
