Which document must be provided if a wholesaler is suspected of selling counterfeit RX drugs?

The correct choice is the transaction statement, which is crucial when investigating the legitimacy of drug sales, especially concerning counterfeit prescriptions. A transaction statement documents the sale or distribution of a prescription drug, detailing the chain of custody and specifying information about the product, such as the lot number, expiration date, and other relevant data. This document is essential for verifying that the wholesaler is complying with regulations and has sourced the medications from legitimate suppliers.

If a wholesaler is suspected of selling counterfeit RX drugs, the transaction statement allows regulatory authorities to trace back through the supply chain, confirming the authenticity of the drugs. It helps ensure that all parties involved in the transaction are reputable and that the drug has not been tampered with or misrepresented.

While other documents like a service agreement, quality control report, or inventory list provide some information about the operation and management of the wholesaler, they do not directly validate the legitimacy of the drug's provenance as effectively as the transaction statement does.
