  1. A health system wants to analyze trends across millions of historical patient records without impacting the live EHR's performance. The best solution is to use a:

    Answer: Data warehouse

    A data warehouse is optimized for large-scale analytical queries on historical data, separate from the operational transactional system.

  2. Role-based access control (RBAC) in an EHR system grants permissions based on:

    Answer: The user's job function or title

    RBAC assigns system access privileges according to a user's defined role or job function within the organization.

  3. In healthcare IT, SOA stands for Service-Oriented Architecture. Its primary advantage for health information systems is:

    Answer: Reusable, loosely coupled services that can be shared across applications

    SOA allows individual services (e.g., patient lookup) to be built once and reused across multiple applications, reducing duplication.

  4. Which system generates automated alerts to clinicians when a patient's orders may cause a drug-drug interaction?

    Answer: Clinical Decision Support System

    Clinical Decision Support Systems (CDSS) analyze patient data against clinical rules to generate alerts, reminders, and recommendations.

  5. A hospital uses a system to assign IDs, merge duplicate records, and maintain a single authoritative list of patients across facilities. This is a:

    Answer: Enterprise Master Patient Index (EMPI)

    An Enterprise Master Patient Index (EMPI) maintains a unique, accurate patient identity record across multiple facilities within a health system.

  6. Which FHIR resource type would be used to represent a patient's documented allergy to penicillin?

    Answer: AllergyIntolerance

    The FHIR AllergyIntolerance resource is specifically designed to capture a patient's risk of adverse reaction to a substance.

  7. Which network topology connects all nodes directly to a central hub or switch, making it easy to add devices but creating a single point of failure?

    Answer: Star topology

    In a star topology, all devices connect to a central hub or switch; if the hub fails, all connected nodes lose connectivity.
