Why are persons who have swallowed a non-petroleum based poison given large quantities of warm soapy water or warm salt water?

Correct Answer: Option B — to induce vomiting

Ingesting non-petroleum based poisons requires dilution and emesis induction using warm soapy or salt water, provided the patient is fully conscious. This dilution reduces mucosal irritation while the induced vomiting expels the toxic substance before systemic absorption occurs.
