Question 1
What is the relationship between a conceptual definition and an
operational definition?
Answer a.
s: The conceptual definition is 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 Operationalizing a variable or a concept involves developing conceptual
Feedback: 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 a.
s: 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
Response p.
Feedback: 24
Question 3
Why is operational reasoning necessary for research?
Answer a.
s: 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 Operational reasoning involves the identification of and discrimination
Feedback 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.”
What is the purpose of the study?
Answer a.
s: 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.
b.

total hours of sleep per 24-hour day.
c.
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.
d.
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.
Response The research purpose is generated from the problem and identifies the
Feedback specific focus or aim of the study. The focus of the study might be to
: identify, describe, explain, or predict a solution to a situation. The
