53. The Controlled Substances Act requires which of the following medications to be stored in a locked cabinet unless it is dispersed among non-controlled pharmaceuticals?

Answer: D

Explanation:

Dextroamphetamine must be stored in a locked cabinet as required by the Controlled Substances Act.

Dextroamphetamine is classified as a controlled substance and must be stored in a locked cabinet unless it is mixed with non-controlled pharmaceuticals, in accordance with the Controlled Substances Act regulations.

A) Dexamethasone

Dexamethasone is a corticosteroid used to treat various conditions but is not classified as a controlled substance. Therefore, it does not have the same storage requirements as controlled medications, making this option incorrect.

B) Dexlansoprazole

Dexlansoprazole is a proton pump inhibitor used for gastroesophageal reflux disease and is also not a controlled substance. As such, it does not require locked storage, rendering this option incorrect as well.

C) Desvenlafaxine

Desvenlafaxine is an antidepressant that is not classified as a controlled substance. Consequently, it does not need to be stored in a locked cabinet, which makes this choice incorrect.

D) Dextroamphetamine

Dextroamphetamine is classified as a Schedule II controlled substance under the Controlled Substances Act. This classification necessitates that it be stored in a locked cabinet to prevent unauthorized access and misuse, confirming this choice as correct.

Conclusion

Dextroamphetamine is the only medication listed that is classified as a controlled substance, thus requiring secure storage in a locked cabinet according to the law. The other options, being non-controlled substances, do not have such stringent storage requirements, which highlights why Dextroamphetamine is the definitive correct answer.
