In a research study, the question is tested with an appropriate design and specific methodology, whereas in evidence-based practice, the question is used to search the research literature to find answers.
A nurse is analyzing a research article. Where in the article is the nurse likely to find the research question and study purpose.
The nurse researcher is conducting a research study using subjects who will be interviewed regarding their experience with postpartum depression. Why would the researcher select a qualitative, rather than quantitative, research design?
Qualitative research collects data from a small number of subjects allowing for in-depth study of a phenomenon.

A hypothesis attempts to answer the question posed by the research problem.
How is a hypothesis related to a theory?
Hypotheses must be consistent with an existing theoretical framework.
A nurse makes these statements. Which one has the greatest potential as an area of nursing research?
"It seems that most of the patient falls on our unit occur during the nightshift."
In a research study, properties of interest that differ in value are:
The most significant difference between independent and dependent variables is:
the dependent variable should change in response to manipulation by the independent variable.
When designing a research study, the nurse should recognize regarding independent and dependent variables:
A given characteristic or situation may be the dependent variable in one study and the independent variable in another.
A nurse's research question is, "How does maternal employment among health care professionals affect infant health during the first 6 months of life?" In this question, the dependent variable is:
The review of literature is important to the research process because:
it guides steps of the research process.
The nurse researcher locates a reappraised commentary for a source of literature. The next step for the researcher should be:
decide whether to locate and critically appraise the primary source.
A nurse researcher includes referred journals in the literature review because:
the articles are critiqued by a panel of external reviewers.
A research article has undergone a blind review for a peer-reviewed journal. The nurse reading the research article should understand which of the following about this review process?
The reviewers of the article did not know the identity of the author.
For which of these reasons would a nurse researcher decide to use secondary sources in a review of the literature?
They supplement the body of nursing knowledge in a specific area of practice.
Which is an example of a primary source in a literature review?
A video recorded interview of a nurse researcher.
Which is an example of a secondary source in a literature review?
A summary and critique of another's scholarly work.
When comparing MEDLINE and CINAHL databases, which of these differences will the nurse find?
MEDLINE's database size is more than 21 million records, whereas CINAHL's database size is more than 3.2 million records.
Which phrase correctly defines a theory?
A set of interrelated concepts that provides a systematic view of a phenomenon.
How are theory and practice interrelated for the hospital-based nurse researcher?
Practice provides the opportunity to test theory.
Situation-specific nursing theories are becoming more popular in nursing research due to:
increased emphasis on evidence-based practice.
A graphic or symbolic representation of a phenomenon not directly observable, which allows the reader to visualize key constructs and their interrelationships, is:
How is a model related to a concept or concepts?
Relationships between or among concepts are demonstrated in a model.
Which statement is an operational definition of a concept?
Death anxiety is an uncomfortable feeling on contemplation of one's own death, measured by Templar's Death Anxiety Scale (Templar, 1986).
When reading a report of results of a nursing research study, the nurse notices that the theoretical framework is drawn from a discipline other than nursing. When critiquing the theoretical framework, the question that should be of highest priority is:
Has the author clearly indicated the meaning of the theoretical framework to the study and linked it to nursing?
The measures used by a nurse researcher to maintain uniformity of conditions in a quantitative research study refer to:
The overall purpose of the research design in a quantitative research study is:
to provide the plan for answering the research question.
In which of these ways does the nurse researcher's literature review help select the appropriate study design?
By objectively assessing available knowledge of the area.
When reviewing a research report, the nurse determines that all aspects of a study systematically and logically follow from the research problem. Which condition has been met?
Which factor is most likely to be a mediating (extraneous) variable in a study to determine if high doses of vitamin C help reduce the subjects' susceptibility to influenza?
The subject's use of influenza vaccine.
A nurse researcher is designing a quantitative research study involving a specific group of patients admitted to local hospitals. Which factor would negatively affect the feasibility of this study?
Potential study subjects represented less than 1% of hospital admissions during the year previous to the study.
A nurse is designing a study to determine whether a videotape or a written pamphlet is more effective in teaching young women how to perform breast self-examination (BSE). Which of these actions would provide the best control for a mediating (extraneous) variable?
Exclude subjects who already perform BSE on a regular basis.
How would a nurse researcher ensure that the sample used in a quantitative study is homogeneous?
Use eligibility criteria to limit extraneous variable relevant to the study.
The nurse is critiquing a research study that used an experimental design. How can the nurse determine if the study's results are able to infer causality?
The relationship between independent and dependent variable must not be explainable by any other variable.
The nurse is critiquing a research study that involves subjects undergoing chemotherapy for breast cancer. Which finding would meet a criterion for inferring causality between performance of exercise and adaptive behavior of the subjects receiving chemotherapy?
The level of adaptive behavior increased in direct proportion to an increase in the intensity of the exercise.
The experimental treatment initiated by a researcher can be described as what kind of variable?
Which of these criteria is most important when evaluating the results of an experimental research study?
The validity that the experimental treatment caused the desired effect on the outcome.
Compared with a quasi-experimental design, which of these characteristics should a nurse expect to see only in a true experimental design?
Which factor should be the primary consideration when determining the validity of experimental study findings?
The extent to which the researcher controlled intervening variables.
In which way is the independent variable handled differently in a study with a true experimental design when compared with a study with a quasi-experimental design?
Although both designs identify an independent variable, the nature of the groups (randomized vs non-randomized) means that manipulation may result in different results.
Random assignment of subjects to experimental and control groups produces which effect?
Decreases systematic bias
What is the first question that should be asked in determining whether a cross-sectional design or a longitudinal design should be used in a quantitative study?
What is the nature of the problem being studied?
Which method of data collection is most appropriate for a nurse researcher to use in a survey study?
Why would a nurse researcher choose to use research studies that examine the associations or relationships between variables?
There is application in clinical settings and a foundation for future experimental studies.
Why would a nurse researcher choose not to use a survey study design?
Information collected is relatively superficial.
A nurse researcher would choose to use a correlational study of multiple variables for which purpose?
To examine relationships between or among variables.
Why would a nurse researcher choose to use a correlational design for a non-experimental study?
It represents an efficient and effective method of collecting a large amount of data about a problem.
A nurse researcher would decide to use a retrospective or ex post facto study because:
the dependent variable has already been affected by the independent variable.
Cause and effect
Cause must precede the effect
relationship must not be explained by another variable
threats to internal validity
Selection, maturation, testing and mortality
