Which type of transactions must a designated representative keep records of?

The correct choice relates to the requirement for designated representatives to maintain records of transactions involving drug purchases. This is a critical responsibility as it ensures compliance with regulations governing the pharmaceutical industry. By keeping detailed records of these transactions, designated representatives can help prevent misuse and abuse of medications, monitor inventory, and support accountability in handling controlled substances and pharmaceuticals.

Documentation of drug purchases is essential for several reasons, including adherence to legal requirements, providing transparency in operations, and facilitating safe distribution practices. Regulatory bodies often mandate that records be kept for inspection to ensure that designated representatives are operating within the law and maintaining ethical standards in managing drug distribution.

In contrast, the other types of transactions mentioned, while possibly relevant in different contexts, do not carry the same regulatory weight or specific documentation requirements tied to the role of a designated representative in the pharmaceutical industry. Financial deals, promotions, and customer feedback, while important for business operations, do not impose the same scrutiny that accompanies drug-related transactions, which are strictly monitored to safeguard public health.
