B is correct because Care Request and Care Request Item are the standard objects in Health Cloud that are used to set up prior authorizations. Care Request represents a request for authorization of a service or procedure, and Care Request Item represents a specific service or procedure within the request. These objects can be integrated with an external system that manages the end-to-end prior authorization process, and display the preauthorization outcomes from that system.

When creating a care plan with a template you can unselect tasks so they will not be included (A), the sort order of the Task group by Fields can be changed under custom setting task group (B), and care plan templates must include at least 1 problem, 1 goal and 1 task are true statements about Care Plan Templates. When creating a care plan with a template you can change the offsets of the tasks (D) is false, as you can only change the offsets of the tasks when creating a care plan without a template. Care plan templates can only be used when creating a new care plan (E) is false, as you can also use care plan templates when editing an existing care plan.

The two objects that support Salesforce's recommended approach to model the doctors in the clinic's Health Cloud org are Contact and Healthcare Practitioner. Contact is used to store the personal information of the doctor, such as name, phone, and email. Healthcare Practitioner is used to store the professional information of the doctor, such as specialty, license, and credentials.

Einstein Analytics Predictions is an add-on license that enhances Health Cloud to allow you to highlight times when a patient is most likely to attend an appointment. It uses machine learning to analyze historical data and generate predictions based on various factors2. Einstein Vision, Einstein Bots, and Einstein Activity Capture are not related to this use case.

A visit is an object that represents a field rep's trip to a retail store or a customer location to perform certain tasks, such as selling products, conducting surveys, or taking orders1. A visit can be created from a work type, which is a template that defines the key parameters and skill requirements for the visit2. A visit can also be associated with a location, which is an object that stores the address and geolocation of a place where a visit can occur3.
A consultant should configure the visit object to track the surgical case visits for reps to sell their product leveraging Intelligent Sales. This way, the reps can use the Intelligent Sales app to create and manage their visits, view their assigned tasks, scan products, and capture signatures4. The consultant can also use work types to standardize the duration, preparation, and wrap-up time for each visit type, and use locations to specify the service territories where the visits can take place.
