Which of the following symptoms is NOT associated with cholinergic toxicity?

Cholinergic toxicity is characterized by an overstimulation of the parasympathetic nervous system due to high levels of acetylcholine. This typically presents with a classic triad of symptoms, which includes increased salivation, lacrimation (tear production), urination, diarrhea, gastrointestinal distress, and bronchoconstriction.

Respiratory depression, however, is not a direct symptom of cholinergic toxicity. Instead, patients may experience bronchoconstriction and increased secretions, which can lead to respiratory distress but not typical respiratory depression. Respiratory depression is more often associated with central nervous system depressants rather than with cholinergic agents. Thus, among the listed symptoms, respiratory depression stands out as the one not typically linked to cholinergic toxicity, thereby making it the correct choice in this context.
