Final answer:
A separate inventory record is required for each Schedule II drug due to their potential for abuse and the strict regulatory controls placed on them. Entities handling these drugs must maintain accurate records, monitored by the DEA.
Step-by-step explanation:
A separate inventory record must be kept for each Schedule II drug. Schedule II drugs are classified under the Controlled Substances Act and consist of substances that have a high potential for abuse, which may lead to severe psychological or physical dependence. These include certain narcotics, stimulants, and depressants. Due to the potential for abuse and addiction, strict regulatory control is placed on these substances to prevent misuse. Pharmacies, hospitals, and other entities that handle these drugs must maintain accurate records for each Schedule II drug, including quantities received, dispensed, and any losses or discrepancies in inventory. The Drug Enforcement Administration (DEA) closely monitors compliance with these regulations.
