  2. ServiceRequest
  3. ImagingStudy
  4. DiagnosticReport
Show answer & explanation

Correct answer: B - ServiceRequest

Question 2

A profile constrains a coded element so that implementers must use a code from a specified value set, and no codes outside that set are permitted under any circumstances. Which binding strength does this describe?

  1. Example
  2. Preferred
  3. Extensible
  4. Required
Show answer & explanation

Correct answer: D - Required

Question 3

An Observation instance contains the element "valueQuantity" populated with a value, unit, and UCUM system. What does the "Quantity" suffix on this element tell you?

  1. The numeric result has been coded against a bound terminology value set
  2. The element is a modifier extension carrying the numeric measurement data
  3. A choice (value[x]) element has been resolved to the Quantity data type
  4. The Observation holds a reference pointing to a separate measurement resource
Show answer & explanation

Correct answer: C - A choice (value[x]) element has been resolved to the Quantity data type

Question 4

On a server that maintains version history, which set of RESTful interactions results in a new entry being added to a resource's history?

  1. read, vread, and search
  2. read, search, and capabilities
  3. create, update, and delete
  4. search, history, and read
Show answer & explanation

Correct answer: C - create, update, and delete

Question 5

A client submits a Bundle containing several entries and requires that either all of them are applied successfully or none of them are. Which Bundle type meets this requirement?

  1. A transaction Bundle, processed atomically
  2. A batch Bundle, with entries applied independently
  3. A collection Bundle, grouping the resources together
  4. A history Bundle, recording prior resource versions
Show answer & explanation

Correct answer: A - A transaction Bundle, processed atomically

Question 6

An implementer needs to invoke a FHIR operation that takes several structured input parameters. How is such an operation correctly invoked?

  1. With a GET request, passing each structured input as a repeated query string parameter
  2. With a POST request whose body is a Parameters resource, using the $ prefix
  3. With a PUT request sent directly to the resource instance being operated upon
  4. By attaching an X-Operation header to any standard RESTful CRUD interaction
Show answer & explanation

Correct answer: B - With a POST request whose body is a Parameters resource, using the $ prefix

Question 7

A client must retrieve every Observation whose effective date is on or after 1 January 2024, including that exact date. Which search expression is correct?

  1. Observation?date=sa2024-01-01
  2. Observation?date=ap2024-01-01
  3. Observation?date=gt2024-01-01
  4. Observation?date=ge2024-01-01
Show answer & explanation

Correct answer: D - Observation?date=ge2024-01-01

Question 8

A POST to create a resource is well-formed and the client is authenticated and authorized, but the server rejects it because a required element violates a business rule. Which HTTP status code best fits this situation?

  1. 400 Bad Request, signalling the payload could not be parsed
  2. 422 Unprocessable Entity, signalling a business-rule violation
  3. 401 Unauthorized, signalling the client identity was not established
  4. 403 Forbidden, signalling the client lacked permission for the action
Show answer & explanation

Correct answer: B - 422 Unprocessable Entity, signalling a business-rule violation

Question 9

A base resource defines an element with cardinality 0..1. Which change is a profile permitted to make to that element?

  1. Narrow the cardinality to 1..1 to make it mandatory
  2. Widen the cardinality to 0..* to allow repetition
  3. Add a new data type the base element does not allow
  4. Relax a required binding to make the element optional-coded
Show answer & explanation

Correct answer: A - Narrow the cardinality to 1..1 to make it mandatory

Question 10

A national project needs to export data for an entire population of patients from a FHIR server for analytics, rather than retrieving records one patient at a time. Which approach is designed for this use case?

  1. The FHIR Messaging paradigm, using a Bundle led by a MessageHeader
  2. A SMART on FHIR app launched in the context of one single patient
  3. The Bulk Data Access (Flat FHIR) Implementation Guide
  4. A transaction Bundle posted to the base server root for processing
Show answer & explanation

Correct answer: C - The Bulk Data Access (Flat FHIR) Implementation Guide
