Which statement indicates a need for further teaching regarding poison prevention?

The statement indicating a need for further teaching regarding poison prevention is the one that suggests making a child vomit after ingesting gasoline. This approach is dangerous and not recommended as a first response to poisoning. Inducing vomiting can cause additional harm, especially if the substance ingested is caustic or could lead to aspiration into the lungs.

Best practices in poison prevention and response emphasize the importance of staying calm and seeking immediate medical assistance. It is crucial to contact poison control or a healthcare professional for guidance on how to proceed after a poisoning incident rather than attempting to induce vomiting or administer fluids unless specifically directed by a medical professional.

The other statements reflect appropriate and informed poison prevention practices, such as properly labeling toxic substances, storing them out of the reach of children, and being cautious about handling situations involving poisoning without attempting potentially harmful interventions.
