Which of the following is a rule for filling out a DEA form?

The correct answer emphasizes the critical importance of accuracy when filling out a DEA form. Regulations surrounding controlled substances are stringent, and all information on the form must be correct to ensure compliance with federal laws. This is essential for maintaining the integrity of record-keeping related to controlled substances, which is paramount in veterinary and medical practices to prevent misuse and ensure accountability.

When submitting a DEA form, inaccuracies can lead to serious legal ramifications and complications in the handling of controlled drugs. Therefore, it's crucial that every detail, such as the names, medication types, quantities, and signatures, is filled out accurately and completely. This focus on precision is foundational in veterinary pharmacology, where the safe dispensing of medications is vital.

In contrast, the other choices suggest practices that may undermine the accuracy or legality of the documentation, but the proper rule is that all information must be correct to ensure compliance with DEA regulations.
