What is the first step to take if a child ingests a potentially poisonous substance?

When a child ingests a potentially poisonous substance, the first step is to call for medical help. This is crucial because the type of poison, the amount ingested, and the time since ingestion play significant roles in determining the appropriate treatment. Medical professionals possess the expertise to provide immediate guidance on what actions to take next, including whether to induce vomiting or administer activated charcoal if that is indicated.

Calling for help ensures that the child receives timely and potentially life-saving care. Medical instruction may also involve staying on the line until help arrives, as certain poisons may require specific interventions that can only be safely and effectively managed by healthcare providers.

Other options, such as giving water, inducing vomiting, or waiting to see symptoms, can be dangerous. For instance, inducing vomiting is not advisable for all types of poisons and could worsen the situation. In summary, reaching out for medical assistance is the most effective and safest initial response in such emergencies.
