Question 1
What is the relationship between a conceptual definition and an
operational definition?
Answer
s:
a.
The conceptual definition is
... [Show More] concrete, and the operational
definition is abstract.
b.
The operational definition allows the researcher to create a
measurable variable from a concept.
c.
They are the same, in most instances.
Response
Feedback:
Operationalizing a variable or a concept involves developing conceptual
and operational definitions. A conceptual definition provides the
theoretical meaning of a concept or variable. The conceptual
definition provides a basis for formulating an operational
definition. An operational definition is derived from a set of
procedures and progressive acts that a researcher performs
either to manipulate an independent variable or to measure
the existence or degree of existence of the dependent
variable.

Question 2
Sources of research topics often come from research priorities developed by
professional organizations and funding agencies. Which of the following is an
example of a research priority in healthcare?
Answer
s:
a.
Effective and appropriate use of technology to achieve optimal patient
assessment, management and/or outcomes
b.
Promotion of literacy in preschoolers
c.
Vaccination of all children regardless of parents’ religious beliefs

Question 3
Why is operational reasoning necessary for research?
Answer
s:
a.
Standard interventions are obtained from operational
reasoning.
b.
It facilitates the researcher’s rapport with families

c.
Abstract concepts are of no use to nursing.
d.
It allows the researcher to measure the concepts
studied.
Response
Feedback
:
Operational reasoning involves the identification of and discrimination
among many alternatives and viewpoints. It focuses on the
process (debating alternatives) rather than on the resolution. Nurses use
operational reasoning to develop realistic, measurable health
goals. Thus, operational reasoning takes abstract concepts and makes
them focused, concrete, and, therefore, researchable.

Question 4
A research study contains the following in its Introduction section: “This study was
undertaken to explore the effect of massage on total hours of sleep per 24-hour day,
in persons averaging fewer than 7 hours of sleep per night, attributable to
insomnia. . . . Presumably by increasing endorphin levels, massage seems to provide
an immediate relaxation and an ability to sleep immediately following the session,
but it is unclear whether these benefits actually extend to total sleep, despite
anecdotal support. The claim that massage increases total hours of sleep has been
inadequately researched. . . . Does massage increase the total number of hours of
daily sleep? . . . It was posited that provision of daily late-morning massage would
affect total hours of sleep per 24-hour day. The study’s causational explanation was
based on the physiologic matrix of McCarthy, which includes effects of endorphins on
sleep, learning ability, pain, digestive function, and cardiac output. . . . It was taken
as established fact that massage is pleasant, that research subjects getting fewer
than 7 hours of sleep per night were sleep-deprived, and that endorphins mediated
the changes observed.”

Question 5
Which of the following statements best describes the relationship between research
and practice?
Answer
s:
a.
Practice limits nursing research to issues that are patient-centered.
b.
Practice does not affect research, but research affects practice.

Question 6
A researcher who desires to determine the cause-and-effect
relationship between the use of a new car seat restraint and the
subsequent rate of children’s spinal cord injury will utilize which form
of nursing research?
Answer
s:
a.
Quantitative
research
b.
Descriptive
research
c.
Qualitative
research
Response
Feedback:
Quantitative research, the most frequently used method, is a
formal, objective, systematic methodology to describe
variables, test relationships, and examine cause-and-effect
interactions. Quantitative research includes experimental
research, which is the method for testing cause-and-effect
relationships between and among specific variables.
Qualitative research methods are used for explaining
meanings and describing experiences in context. Descriptive
research involves identifying and understanding the nature
of phenomena and, sometimes, the relationships among
them. Outcomes research examines the end result of care in
huge populations, most often retrospectively, using a

Question 7
Control occurs when the researcher imposes “rules” to decrease the possibility of
error and thus increases the probability that the study’s findings are an accurate
reflection of reality. Which type of research design has the highest level of control in
a study?
Answer
s:
a.
Descriptive research
b.
Correlational research
c.
Experimental research
d.
Quasi-experimental
research
Response
Feedback:
Control occurs when the researcher imposes “rules” to decrease the
possibility of error and thus increases the probability that the study’s
findings are an accurate reflection of reality. Descriptive and
correlational studies are usually conducted with minimal control of the
study design, because subjects are examined as they exist. In
experimental research, the independent and dependent variables are
highly controlled, the researcher exerts high control over the planning
and implementation of the study, and often these studies are conducted
in a laboratory setting on animals or objects. If a research study
randomly assigns subjects to two different groups, applies an
intervention to one of the groups, and then measures both groups and
compares them, it is experimental design.
