Which of the following is NOT a sign of pesticide poisoning?

Improved alertness is not a sign of pesticide poisoning because pesticide poisoning typically causes symptoms that indicate a toxic reaction in the body. Common indicators of pesticide poisoning include nausea, headaches, and skin irritation, all of which reflect distress or adverse effects experienced by the body in response to toxic substances. Nausea suggests gastrointestinal distress, headaches often point to neurological effects, and skin irritation indicates dermal reactions to the pesticide. In contrast, improving alertness runs counter to the expected symptoms, as poisoning usually leads to drowsiness, confusion, or decreased cognitive function rather than enhanced alertness. This distinction is important for identifying pesticide-related health risks effectively.
