B is correct because if a user cannot access a field used in a filter on a patient or member list, they will not be able to see the list. This is because the filter criteria are applied to the user's query, and if the user does not have permission to view the field, the query will return no results. To avoid this issue, the administrator should ensure that the user has the appropriate field-level security settings for the fields used in the filter.

To enable viewing medication data from Salesforce Health Cloud while leveraging FHIR standards, the Clinical Data Model is the correct data model to use.
Why the Clinical Data Model?
Purpose and Design:
The Clinical Data Model in Health Cloud is specifically built to represent patient health data, including medications, allergies, conditions, and other clinical information.
It adheres to FHIR (Fast Healthcare Interoperability Resources) standards, which are widely used to facilitate the exchange of electronic health information between systems.
Medication Data Representation:
The Clinical Data Model contains FHIR-compliant objects, such as MedicationRequest and MedicationStatement, to store and retrieve information about prescribed medications, their dosages, and administration details.
FHIR Integration:
Health Cloud's Clinical Data Model supports RESTful FHIR APIs, allowing external systems to access medication data seamlessly.
FHIR compatibility ensures that medication data can be shared with third-party EHR systems and healthcare applications.
Implementation Steps:
Configuration of Medication Records:
Populate the FHIR-compliant objects with medication data, ensuring adherence to the FHIR R4 resource structure.
Use of FHIR APIs:
Enable the Clinical Summary Healthcare API or specific Medication APIs (e.g., GET /MedicationRequest) to fetch and display medication details.
Integration Testing:
Validate the FHIR-based data exchange with other systems to ensure seamless interoperability.
