Final answer:
It is true that a complete inventory must be taken on the day of transfer when transferring controlled substances to another pharmacy. This is to adhere to DEA regulations and ensure accurate tracking to prevent misuse.
Step-by-step explanation:
A statement saying that a complete inventory must be taken on the day of transfer when transferring controlled substances to another pharmacy is indeed true. Regulations concerning the handling of controlled substances are very strict to prevent misuse and to ensure proper tracking. These substances are categorized under different 'schedules' which reflect their potential for abuse. When a pharmacy transfers these substances, they have to comply with the Drug Enforcement Administration (DEA) regulations, and part of that compliance involves taking a full inventory to accurately document what is being transferred. This helps to maintain the integrity of the tracking process and prevent diversion of these substances. Should any discrepancies arise, the inventory can serve as a crucial record for clarifying what was supposed to have been transferred, and proper actions can be taken in light of that information.
