Explanation
The two reasons that explain why Integration Procedures are recommended as the first choice of data sources for FlexCards and OmniScripts are: they future-proof your front-end design and they combine multiple actions into a single server call. An Integration Procedure can abstract the data source from the front-end design, making it easier to change or update the data source without affecting the FlexCard or OmniScript. An Integration Procedure can also execute multiple DataRaptor actions, such as Extract, Transform, and Load, and also invoke REST or SOAP services in one call, reducing the number of requests and processing time

Explanation
The most efficient way to meet the requirements is to create a FlexCard with two card states. A card state defines how a FlexCard displays data and actions based on certain conditions. The consultant can use conditions on the state to filter for priority, and then customize the fields and actions for each state. This way, the FlexCard can display different information and options for low/medium and high priority cases

An advantage of calculation procedures that the consultant should highlight in this scenario is that they allow multiple versions that will execute based on when the request is made. A calculation procedure can have different versions with different effective dates, which determine when they are active or inactive. This way, the calculation procedure can use different rating or pricing tables depending on the date of the request, and handle frequent changes in prices

Explanation
The solution that the consultant should recommend is DataRaptor Turbo Extract. DataRaptor Turbo Extract allows the designer to retrieve a large amount of data from a Salesforce object in batch mode without hitting governor limits. DataRaptor Extract is not suitable for this scenario, as it can only retrieve data from a single record or a small set of records. Calculation Procedure and DataRaptor Turbo Extract are not needed for this scenario, as there is no calculation involved. Integration Procedure and DataRaptor Turbo Extract are not needed for this scenario, as there is no data integration involved.

The OmniStudio tools that the consultant should use to design a solution to meet these requirements are:
Single FlexCard with multiple actions. A FlexCard is a tool that can display data and actions in a card format.
The consultant can use a single FlexCard to display the medical test reports for each patient, including the report name, date requested, and date generated. A FlexCard can also have multiple actions, such as buttons or links, that can invoke OmniScripts or Integration Procedures. The consultant can use multiple actions to enable the user to approve, print for review, or send for retest each medical test report
