Which of the following is a common sign of pesticide poisoning?

Dizziness is a common sign of pesticide poisoning. When a person is exposed to pesticides, the chemicals can impact the nervous system and various bodily functions, often leading to symptoms such as dizziness, headaches, nausea, and disorientation. This occurs because pesticides can interfere with neurotransmitter function and alter normal physiological processes.

In contrast, the other options presented are not associated with pesticide poisoning. Increased energy, enhanced cognitive function, and improved respiratory capacity are not typical responses to exposure. Rather, pesticide exposure usually results in a decline in these areas due to the toxic effects on the body. Understanding the symptoms associated with pesticide poisoning is crucial for timely recognition and treatment, ensuring safety for applicators and those in the vicinity of pesticide applications.
