WGU D118: OA Study Guide: Questions & 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?
- Quasi-experimental
- Qualitative
- Experimental
- 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?
- Quasi-experimental
- Qualitative
- Experimental
- Descriptive
(- ANS: C
- / 4
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?
- Quasi-experimental
- Qualitative
- Experimental
- 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?
- Quasi-experimental
- Qualitative
- Experimental
- 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?
- To define characteristics of interest of groups of patients
- To demonstrate the effectiveness of an intervention or treatment
- To describe relationships among characteristics or variables
- 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?
- To define characteristics of interest of groups of patients
- To demonstrate the effectiveness of an intervention or treatment
- To describe relationships among characteristics or variables
- 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?
- To define characteristics of interest of groups of patients
- To demonstrate the effectiveness of an intervention or treatment
- To describe relationships among characteristics or variables 3 / 4
- 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?
- To define characteristics of interest of groups of patients
- To demonstrate the effectiveness of an intervention or treatment
- To describe relationships among characteristics or variables
- To evaluate the nature of relationships between two variables
(- ANS: B
Level IV research is conducted to demonstrate the effectiveness of interventions or treatments.
