How should Castor bean toxicity be treated if ingestion was recent?

In cases of Castor bean toxicity, the most effective initial treatment for recent ingestion is to induce emesis, followed by the administration of activated charcoal. Castor beans contain ricin, a highly toxic compound, and when ingestion occurs, prompt action is crucial to minimize absorption and mitigate the effects of the toxin.

Inducing emesis helps remove the toxic material from the gastrointestinal tract if it is performed soon after the ingestion. The use of activated charcoal is important as well because it binds to toxins in the digestive system, preventing further absorption into the bloodstream. This combined approach increases the chances of reducing the severity of the toxicity and supporting the animal's recovery.

The other options do not address the urgent need for detoxification effectively. Immediate surgery is not typically warranted unless there are specific complications that necessitate it, and simply administering fluids or providing only supportive care after recent ingestion would likely fail to prevent the adverse effects associated with ricin poisoning.
