Final answer:
The statement that needs correction is that the trademark for generic names is indicated by the superscript TM. Generic names are not trademarked; trademarks apply to brand names.
Step-by-step explanation:
The statement about medication names that requires correction is "The trademark for generic names is indicated by the superscript TM." Trademarks are related to brand names, not generic names of medications. The nonproprietary or generic name is the standardized name given to a drug and is not trademarked. The United States Adopted Names Council is responsible for approving these names. Additionally, the Institute for Safe Medication Practices does indeed publish a list of medications that are frequently confused with other medications to help prevent errors.
