A hospital is undergoing a major reconstruction project and a new director of nursing has been
hired. At the same time, the nursing documentation component of the EHR has been
implemented. The fact that nursing staff satisfaction scores have risen is:
a. A result of anecdotal benefits of EHR
b. A result of qualitative benefits of EHR
c. A result of reconfiguration of the nursing units
d. Uncertain due to existence of confounding variables - Answer✔d. Uncertain due to existence
of confounding variables
In this situation there are too many changes occurring at the same time to determine what is
improving the nursing staffing satisfaction scores. Any one item could be the reason for the
improvement. To evaluate the impact of the electronic health record (EHR) nursing
documentation component, a benefits realization study should have been utilized. This would
have studied the impact of the EHR component before and after implementation (Amatayakul
2017, 106).
If a health plan analyst wanted to determine if the readmission rates for two hospitals were
statistically different, what is the null hypothesis?
a. The readmission rates are not equal.
b. The readmission rates are equal.
c. The readmission rate for one hospital is larger than the other.

d. The readmission rate for one hospital is smaller than the other. - Answer✔b. The readmission
rates are equal.
The first step in statistical hypothesis testing is defining the null and alternative hypotheses. The
null hypothesis is the status quo. In this example the readmission rates are equal would be the
null hypothesis showing no relationship between the two hospitals (White 2016a, 65).
What architectural model of health information exchange allows participants to access data in
point-to-point exchange?
a. Consolidated
b. Federated—consistent databases
c. Federated—inconsistent databases
d. Switch - Answer✔c. Federated—inconsistent databases
The Federated—inconsistent databases—model for HIE includes multiple enterprises agreeing
to connect and share specific information in a point-to-point manner (Amatayakul 2017, 417-

Which of the following lists represents recommended core data elements for the master
patient index?
a. Date of birth, revenue code, accession number, and address
b. Name, address, revenue code, and accession number
c. Name, gender, address, and date of birth
d. Gender, address, accession number, and charge code - Answer✔c. Name, gender, address,
and date of birth
A master patient index (MPI) is an index of known patients within a single organization whose
visits are linked together by a single identifier, typically the medical records number. Some
recommended core data elements for the MPI are: name, address, gender, date of birth, and
many others. Accession number, revenue code, and charge code are not recommended core
data elements for the MPI (Reynolds and Sharp 2016, 130).

A technique that describes an interaction between a user and a system is called a(n):
a. Use case analysis
b. RHIO
c. Test case
d. Use description - Answer✔a. Use case analysis
A use case analysis is a technique that describes an interaction between a user and a system. A
use case diagram displays the relationship among actors and use cases. The two main
components of a use case diagram are use cases and actors. An actor represents a user or
another system that will interact with the system being modeled. A use case is an external view
of the system that represents some action the user might perform in order to complete a task
(Oachs 2016, 824-825).
