Pharmacy Technician Certification Exam Practice Question

Correct Answer: A

Rationale: Storing hazardous substances in a locked or secured cabinet ensures that they are inaccessible to unauthorized individuals, particularly children, thereby minimizing the risk of accidental exposure or misuse.

Option B, while important, does not address the critical need for security; warning labels alone do not prevent access. Option C is inappropriate as placing hazardous substances on the top shelf increases the risk of accidental spills or falls, and does not provide security. Option D is misleading; not all hazardous substances require refrigeration, and improper storage can lead to chemical instability or reactions.
