What should be done with all narcotics to ensure safety?

To ensure safety and prevent misuse or accidental ingestion of narcotics, they must be stored in a locked cabinet. This practice minimizes the risk of unauthorized access, which is particularly important given the high potential for abuse and addiction associated with narcotic medications. A locked cabinet helps safeguard these substances not only from patients but also from visitors and staff who may not require access to them.

The other options are less secure and do not provide the necessary protection. Displaying narcotics openly could lead to theft or unintentional access. Storing them in any cabinet does not guarantee security, as it may not be specifically designed to prevent unauthorized access. Keeping narcotics in a refrigerator, while potentially suitable for some medications, does not address the primary concern of preventing access to those who should not have it. Therefore, a locked cabinet is the most appropriate solution for ensuring the safety of narcotics.
