A purchaser is responsible for filling in which details for each Schedule II order on DEA Form 222?

When completing each Schedule II order on DEA Form 222, the purchaser must provide specific details that are crucial for tracking and managing controlled substances effectively. The correct details include the package size, the name of the item, the signature of an authorized individual (which ensures that the order is legitimate), and the date.

Filling in this information is essential because it aids in maintaining the integrity of controlled substance distribution and allows for proper accountability in managing high-risk medications, which are categorized as Schedule II substances. The package size and item name help in identifying exactly what is being ordered and received, while the required signature confirms authorization and responsibility for the order. The inclusion of the date supports transaction tracking within the allowed timeframe for processing orders.

The other options do not include the accurate details mandated for completion of DEA Form 222. For instance, payment methods and supplier information are not required entries on this form, underscoring the importance of strict adherence to regulatory requirements in controlled substance transactions.
