If you're building master patients manually in MST, the master patient tab might have you log in as these users to perform the patient build.

• A. Training users
• B. Guest users
• C. Historical build users/providers
• D. System administrators

Answer: (C)

When building master patients in MST, you log in as historical build users/providers to create the records. These accounts exist specifically to represent the people and providers who historically contributed to those master records, giving the build authentic provenance and the correct provider associations. Using them ensures the created master patient carries the proper creator/owner and auditing context, and aligns with any templates or rules tied to historical builds. Training or guest users generally don’t have the necessary permissions or provenance, and system administrators would bypass the intended workflow, risking unclear audit trails. So the designated historical build users/providers are the appropriate choice for this task.
