Final answer:
The correct response when someone has ingested a poison is never to induce vomiting if the poison is corrosive. Instead, seek emergency help and provide information on the ingested substance. Treatment varies based on the poison, and there is no universal antidote.
Step-by-step explanation:
When a patient has ingested poison, the first course of action is to assess the situation and not induce vomiting immediately. The correct answer to the given choices is option 4) Never induce vomiting if the ingested poison is a corrosive. Corrosive poisons, such as strong acids or alkalis, can cause additional harm to the esophagus and mouth on the way back up if vomiting is induced. It's crucial to call emergency services and, if possible, provide them with information about the poison consumed. In some cases, activated charcoal may be administered if advised by a medical professional, as it can absorb some poisons in the gastrointestinal tract and reduce their absorption by the body. However, there is no universal antidote for all poisons, and the treatment must be specific to the substance that has been ingested.
It is important to remember safety guidelines, such as always checking with a teacher or professional on how to handle chemical spills and disposal, especially in a laboratory setting. When dealing with any chemicals, always refer to their safety data and follow instructions precisely to prevent accidental poisoning.
