What is the treatment for a pediatric patient over 1 year old who has ingested something within the last hour?

Activated charcoal is commonly used in cases of poisoning or overdose, particularly in patients who have ingested toxic substances. For pediatric patients over one year old, administering activated charcoal orally (PO) is a standard treatment protocol if the ingestion occurred within the last hour.

The dosage of activated charcoal is typically based on the child's weight and the severity of the ingestion. A 25g oral dose of activated charcoal is appropriate for this population because it is effective in binding many types of toxins, thereby reducing their absorption into the gastrointestinal tract. This helps to prevent further systemic effects from the ingested substance.

The other options involving intravenous or intramuscular routes of administration are not appropriate in this context. Activated charcoal is not effective when given via IV or IM because it needs to work through binding the toxin in the gastrointestinal system. Additionally, options that prescribe either lower or higher doses may not provide the optimal benefit for treating cases of ingestion in pediatric patients over 1 year old. Thus, choosing the correct oral dose that effectively helps in managing the situation is crucial, and 25g PO aligns with the recommended protocols for this scenario.
