Which safety practice is considered essential when handling high-value controlled medicines in a medical store?

• A. Dual verification
• B. Tamper-evident packaging
• C. Secure storage
• D. Strict access control

Answer: (D)

Limiting who can access high-value controlled medicines is the key safety measure because it directly prevents unauthorized handling. When access is strictly controlled, only approved personnel can enter storage areas or handle these medicines, and each interaction is recorded. This creates clear accountability, supports regulatory requirements, and makes it much harder for someone to divert drugs without leaving a trace. Implementing strict access control typically involves unique user IDs or codes, authenticated sign-in, restricted entry to the storage area, and an audit trail of who accessed what and when.

Other safety measures like dual verification, tamper-evident packaging, and secure storage are important for ensuring accuracy, protecting integrity, and securing the physical environment, but they do not by themselves prevent unauthorized entry. Strict access control provides the fundamental barrier against who can actually handle the medicines in the first place.
