Which signs are associated with poisoning?

• A. Dilated pupils, excessive salivation, discoloration around the mouth, AMS - clumsy/confused, vomiting, loose/bloody stool
• B. Severe dehydration, tachycardia, and dry mouth
• C. Dilated pupils only
• D. Tremors and tremulousness

Answer: (A)

Signs of poisoning often involve both the nervous system and autonomic responses, and you may see a mix of pupil changes, secretions, local signs from ingestion, altered mental status, and gastrointestinal symptoms. Dilated pupils reflect autonomic disturbance, while excessive salivation indicates active secretory responses to a toxin. Discoloration around the mouth can point to ingestion of a caustic or toxic substance, and confusion or clumsy behavior shows central nervous system involvement. Vomiting and diarrhea are common GI responses to poisoning as the body tries to expel the toxin. When these signs appear together, they create a pattern that strongly suggests poisoning.

The other options don’t fit as well. Severe dehydration presents mainly with dry mouth, tachycardia, and other volume-depletion signs rather than a mix of CNS changes plus secretions and oral signs. Dilated pupils alone lack context and aren’t specific to poisoning. Tremors can occur with various conditions and don’t, by themselves, indicate poisoning.
