46. A pharmacy must utilize a DEA Form 222 or CSOS to order:

Answer: D

Explanation:

A pharmacy must utilize a DEA Form 222 or CSOS to order hydromorphone.

Hydromorphone is classified as a Schedule II controlled substance, requiring a DEA Form 222 or the Controlled Substance Ordering System (CSOS) for ordering. This regulation ensures proper tracking and accountability for substances that have a high potential for abuse.

A) guaifenesin/codeine.

Guaifenesin/codeine is a combination product that contains codeine, which is classified as a Schedule III controlled substance. While it does require a prescription, it does not necessitate a DEA Form 222 for ordering, making this option incorrect.

B) acetaminophen/codeine.

Acetaminophen/codeine is also a combination product that falls under Schedule III. Similar to guaifenesin/codeine, it requires a prescription but does not require a DEA Form 222 for ordering, rendering this option incorrect.

C) naloxone.

Naloxone is used to counteract opioid overdoses and is not classified as a controlled substance. Therefore, it does not require a DEA Form 222 or CSOS for ordering, making this option incorrect.

D) hydromorphone.

Hydromorphone is a potent opioid analgesic classified as a Schedule II controlled substance. The strict regulations surrounding its distribution necessitate the use of a DEA Form 222 or CSOS for ordering, confirming this option as correct.

Conclusion

The requirement for a DEA Form 222 or CSOS is specifically tied to the classification of substances as Schedule II controlled drugs, which includes hydromorphone. All other options listed are either Schedule III substances or non-controlled, thus not necessitating the same level of regulatory oversight. This distinction highlights the importance of compliance in the handling of controlled substances within pharmacy practice.
