Final answer:
Immediate medical attention is crucial if a button battery is swallowed, as it can cause severe internal damage. In cases of radioactive material ingestion, information on the type, amount, and timing is required to assess potential harm. Chemical ingestion also necessitates abstaining from food or drink until evaluated by a medical professional.
Step-by-step explanation:
If a button battery has been swallowed and has passed into the stomach, it is important to seek medical attention immediately, even if there are no immediate symptoms. Button cells can cause severe internal burns and significant injury or even death. It is imperative to go to the emergency department of a hospital where they may perform an X-ray to locate the battery. The medical team can then decide whether the battery can pass through the digestive system naturally or if it needs to be removed. If a person swallows some radioactive material by accident, it is also critical to seek medical attention to assess possible damage. Factors to consider would include the type and amount of radioactive material swallowed, the time since ingestion, and any symptoms the person is experiencing. In cases of chemical ingestion, it is important that the individual does not eat or drink anything, as it may exacerbate the situation.
