Final answer:
Inducing vomiting if a child swallows lighter fluid is not recommended and further teaching is necessary.
Step-by-step explanation:
The statement that indicates further teaching is necessary is: I should induce vomiting if my child swallows lighter fluid. While it is important to call a poison control center immediately in case of any ingestion or contact with a poisonous substance, inducing vomiting should not be done unless instructed by a healthcare professional. It is best to follow the advice of the poison control center or seek medical attention to determine the appropriate course of action.
