Final answer:
Separate inventory records are required for each Schedule II drug due to their high potential for abuse and medical usage, demanding stringent tracking and compliance with federal regulations. The correct option is B.
Step-by-step explanation:
A separate inventory record must be kept for each Schedule II drug. The Controlled Substances Act (CSA) in the United States categorizes drugs into different schedules based on their potential for abuse, with Schedule I having the highest potential for abuse and Schedule V the lowest.
Schedule II drugs have a high potential for abuse which may lead to severe psychological or physical dependence, but also have currently accepted medical uses in the US. Therefore, strict inventory records must be maintained for these substances to prevent misuse and to ensure compliance with federal regulations. Examples of Schedule II drugs include oxycodone, fentanyl, and amphetamines.
