An audit trail is defined as which of the following?

• A. a log of meetings and events
• B. an electronic tool that can track system access by an individual user who viewed a specific client record
• C. a proactive tool to monitor who will be using a system and modifying data
• D. used primarily as a data integrity tool

Answer: (B)

The concept being tested is audit trails in health informatics—the recorded history of who did what in a system, when, and where. An audit trail is an electronic log that captures system access and actions tied to individual users and specific records, so you can see who viewed a client’s record and what they did with it, along with the exact timestamps.

This option fits best because it describes an electronic mechanism that tracks access by an individual user to a specific client record, which is the essence of an audit trail: traceability and accountability for activities within the system.

The other ideas miss the core function. A general log of meetings and events isn’t tied to system-level access or data actions. A proactive monitoring tool describes planning who will use the system, rather than recording what has actually happened. While audit trails support data integrity, their primary purpose is to provide a verifiable record of who accessed or modified data and when, enabling accountability and potential investigations.
