Answer to Question 1

ANS: A, C, D
Storing current and former names of a patient, coordinating various identifiers a patient uses, and providing a unique identifier for each patient are characteristics of a master person index (MPI). The MPI is not used to store clinical information.

Answer to Question 2

ANS: A, B, C
Examples of how clinical applications are tied to other components of the EHR infrastructure include searching and extracting data from a repository, using the data dictionary to code assessment information, and utilizing CDSS rules to assist in ordering the appropriate lab test. The other two choices are not examples of how clinical applications use other EHR components.
