WGU D118: OA Study Guide (Complete) Questions With
100% Correct Answers.
Question 1
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
E) Correlational
Correct Answer: B) Qualitative
Rationale: Qualitative research methods, such as interviews and
focus groups, are used to collect non-numerical data to explore
experiences, perspectives, and meanings, aligning with the APRN's
data collection approach.
Question 2
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, with one receiving a new
intervention and the other receiving standard care. Which type of research
design is being used by the APRN?
A) Quasi-experimental
,B) Qualitative
C) Experimental
D) Descriptive
E) Correlational
Correct Answer: C) Experimental
Rationale: Experimental research is characterized by random
assignment of participants to intervention (treatment) and control
groups, allowing for strong conclusions about cause-and-effect
relationships.
Question 3
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, one receiving a new
intervention and the other receiving standard care. Which type of research
design is being used by the APRN?
A) Quasi-experimental
B) Qualitative
C) Experimental
D) Descriptive
E) Correlational
Correct Answer: A) Quasi-experimental
Rationale: A quasi-experimental design involves a controlled
,intervention but lacks random assignment of participants to groups.
This makes it more challenging to establish direct cause-and-effect
but is often used when random assignment is not feasible or ethical.
Question 4
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 make up a population of patients with Type 2
diabetes (e.g., demographics, common symptoms, lifestyle factors). Which
type of research design is being used by the APRN?
A) Quasi-experimental
B) Qualitative
C) Experimental
D) Descriptive
E) Correlational
Correct Answer: D) Descriptive
Rationale: Descriptive research aims to systematically describe the
characteristics of a population, phenomenon, or situation. It
addresses "what" questions rather than "how" or "why."
Question 5
What is the primary purpose of Level I research in the hierarchy of evidence?
A) To describe relationships among characteristics or variables.
B) To demonstrate the effectiveness of an intervention or treatment.
, C) To evaluate the nature of relationships between two variables.
D) To define characteristics of interest of groups of patients.
E) To conduct randomized clinical trials.
Correct Answer: D) To define characteristics of interest of groups of
patients.
Rationale: Level I research typically involves foundational studies
that describe populations or phenomena, setting the stage for
further investigation.
Question 6
What is the primary purpose of Level II research in the hierarchy of evidence?
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.
E) To conduct randomized clinical trials.
Correct Answer: C) To describe relationships among characteristics or
variables.
Rationale: Level II research moves beyond simple description to
explore how different characteristics or variables are related to
each other.
Question 7
What is the primary purpose of Level III research in the hierarchy of
