WGU D118: OA Study Guide (Complete) Questions With
100% Correct Answers.
An advanced practice registered nurse (APRN) is gathering data for an ongoing
research project. In the project, the APRN is interviewing individual patients as
well as conducting focused group sessions with multiple patients. Which type of
research design is being used by the APRN?
a. Quasi-experimental
b. Qualitative
c. Experimental
d. Descriptive
ANS: B
Qualitative research relies on data obtained by the researcher from first-hand
observation, interviews, questionnaires (on which participants write descriptively), focus
groups, participant observation, recordings made in natural settings, documents, case
studies, and artifacts.
An advanced practice registered nurse (APRN) is gathering data for an ongoing
research project. In the project, a group of individuals with Type 2 diabetes are
divided into two randomized groups. Which type of research design is being used
by the APRN?
a. Quasi-experimental
b. Qualitative
c. Experimental
d. Descriptive
ANS: C
In an experimental research study, the participants in both the treatment and control
groups are randomly assigned.
An advanced practice registered nurse (APRN) is gathering data for an ongoing
research project. In the project, a group of individuals with Type 2 diabetes are
divided into two non-randomized groups. Which type of research design is being
used by the APRN?
a. Quasi-experimental
b. Qualitative
c. Experimental
d. Descriptive
ANS: A
A quasi-experimental design does not randomly assign participants to treatment or
control groups for comparison.
,An advanced practice registered nurse (APRN) is gathering data for an ongoing
research project. In the project, the APRN is focusing on identifying the
characteristics that makeup a population of patients with Type 2 diabetes. Which
type of research design is being used by the APRN?
a. Quasi-experimental
b. Qualitative
c. Experimental
d. Descriptive
ANS: D
Descriptive Research is used to describe characteristics of a population or phenomenon
being studied. It does not answer questions about how/when/why the characteristics
occurred. Rather it addresses the "what" question (what are the characteristics of the
population or situation being studied?).
What is the purpose of Level I research?
a. To define characteristics of interest of groups of patients
b. To demonstrate the effectiveness of an intervention or treatment
c. To describe relationships among characteristics or variables
d. To evaluate the nature of relationships between two variables
ANS: A
Level I research is conducted to define the characteristics of groups of patients.
What is the purpose of Level II research?
a. To define characteristics of interest of groups of patients
b. To demonstrate the effectiveness of an intervention or treatment
c. To describe relationships among characteristics or variables
d. To evaluate the nature of relationships between two variables
ANS: C
Level II research is concerned with describing the relationships among characteristics or
variables.
What is the purpose of Level III research?
a. To define characteristics of interest of groups of patients
b. To demonstrate the effectiveness of an intervention or treatment
,c. To describe relationships among characteristics or variables
d. To evaluate the nature of relationships between two variables
ANS: D
Level III research evaluates the nature of the relationships between two variables.
What is the purpose of Level IV research?
a. To define characteristics of interest of groups of patients
b. To demonstrate the effectiveness of an intervention or treatment
c. To describe relationships among characteristics or variables
d. To evaluate the nature of relationships between two variables
ANS: B
Level IV research is conducted to demonstrate the effectiveness of interventions or
treatments.
Which is the most appropriate research design for a Level I research study?
a. Epidemiological studies
b. Experimental design
c. Qualitative studies
d. Randomized clinical trials
ANS: C
Qualitative designs are useful for Level I
Which is the most appropriate research design for a Level II research study?
a. Epidemiological studies
b. Experimental design
c. Qualitative studies
d. Randomized clinical trials
ANS: A
Epidemiological studies are appropriate for level II studies.
Which is the most appropriate research design for a Level III research study?
a. Epidemiological studies
b. Experimental design
c. Qualitative studies
d. Randomized clinical trials
ANS: B
The experimental design is the most appropriate design for a Level III study.
, Epidemiological studies are appropriate for level II studies. Qualitative designs are
useful for Level I studies. Randomized clinical trials are used for Level IV studies.
Which is the most appropriate research design for a Level IV research study?
a. Epidemiological studies
b. Experimental design
c. Qualitative studies
d. Randomized clinical trials
ANS: D
Randomized clinical trials are used for Level IV studies.
What is the purpose of clinical research trials in the spectrum of translational
research?
a. Adoption of interventions and clinical practices into routine clinical care
b. Determination of the basis of disease and various treatment options
c. Examination of safety and effectiveness of various interventions
d. Exploration of fundamental mechanisms of biology, disease, or behavior
ANS: C
Clinical research trials are concerned with determining the safety and effectiveness of
interventions. Adoption of interventions and practices is part of clinical implementation.
Determination of the basis of disease and treatment options is part of the preclinical
research phase. Exploration of the fundamental mechanisms of biology, disease, or
behavior is part of the basic research stage.
What is a goal of the Healthy People initiative?
a. To increase a patient's quality of life
b. To create physical environments that promote proper health
c. To achieve health equality by eliminating disparities
d. To provide free health care to those unable to pay for care e. To promote
healthy behaviors across all life stages
ANS: C
Overarching goals of the Healthy People initiative are to increase quality and length of
life, free of preventable disease, disability, injury, and premature death; to achieve
health equality by eliminating disparities; to create social and physical environments that
promote proper health; and to promote increased quality of life, healthy development,
and healthy behaviors across all life stages, all goals consistent with the definition of
wellness. Free health care is not a stated goal of the initiative.
