Final answer:
Controlled substances that must be logged separately are likely Schedule II drugs, which have a high potential for abuse but are available for medical use. Schedule II drugs require stringent record-keeping and are stored securely compared to substances in Schedules III, IV, and V.
Step-by-step explanation:
The schedule of controlled substances that must be logged separately from other controlled substances is Schedule I. These substances are defined as drugs or other substances that have a high potential for abuse, have no currently accepted medical use in treatment in the United States, and there is a lack of accepted safety for use of the drug under medical supervision. In the context of medication management and pharmacy operations, Schedule I drugs are not typically stocked in a pharmacy because they are not available for prescribing. However, the question may be referring to Schedule II substances which require stricter record-keeping compared to Schedules III, IV, and V due to their high potential for abuse and the fact that they are legally available for medical use. Schedule II drugs require separate inventory records, securely stored inventory, and specific order forms (DEA Form 222) for procurement.
