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?
