Explanation:

1. In cases of organophosphate or cholinergic agent exposure, airway maintenance is crucial as these agents can cause respiratory - related issues.
2. Patient age has no direct relation to the nature of the poison. Scattered pills, chemicals, and a needle/syringe can give clues about the poison type.
3. Injected poisons are absorbed over time. They cannot be easily removed and are not limited to intravenous drugs, and dilution after injection is not straightforward.
4. The major side - effect of ingesting activated charcoal is constipation.
5. Alcohol, as a central nervous system depressant, slows reflexes.
6. Ativan is a benzodiazepine, not a narcotic. Heroin, morphine, and codeine are narcotics.
7. Inducing vomiting is not part of the treatment for patients with sedative - hypnotic overdose and respiratory depression as it can lead to aspiration.
8. Anticholinergic medications block the parasympathetic nerves.
9. Smoking crack allows for the most rapid absorption and thus the most potent effect.
