What must be changed within 48 hours if a pharmacy entry occurs without a pharmacist's presence?

When a pharmacy entry occurs without a pharmacist's presence, it is crucial to change the alarm code within 48 hours to ensure the security and protection of the pharmacy. This measure is implemented to prevent unauthorized access and to maintain a secure environment for both controlled substances and pharmaceutical inventory. Additionally, changing the alarm code following such an incident helps mitigate potential risks associated with theft or diversion of medications, ensuring compliance with state and federal regulations regarding pharmacy security.

Other options, such as changing pharmacy hours, the technician's ID, or the pharmacy location, do not directly address the immediate security concerns necessitated by a pharmacist's absence during an entry. The focus on alarm codes reflects the pharmacy's commitment to safeguarding its operations and maintaining the integrity of patient safety standards. Thus, prompt action regarding the alarm code is essential in this scenario.
