1. A nurse has conducted a literature review in an effort to identify the effect of hand washing on
the incidence of nosocomial (hospital-acquired) infections in acute care settings. An article
presented findings at a level of significance of <0.01. This indicates that
A) the control group and the experimental group were more than 99% similar.
B) the findings of the study have less than 1% chance of being attributable to chance.
C) the effects of the intervention were nearly zero.
D) the clinical significance of the findings was less than 1:100.
Ans: B
Feedback: The level of significance is the level at which the researcher believes that the study results
most likely represent a nonchance event. A level of significance of <0.01 indicates that there is less
than 1% probability that the result is due to chance.
2. A nurse has read a qualitative research study in order to understand the lived experience of parents
who have a neonatal loss. Which of the following questions should the nurse prioritize when
appraising the results of this study?
A) How well did the authors capture the personal experiences of these parents?
B) How well did the authors control for confounding variables that may have affected the findings?
C) Did the authors use statistical measures that were appropriate to the phenomenon in question?
D) Were the instruments that the researchers used statistically valid and reliable?
Ans: A
Feedback: Qualitative studies are judged on the basis of how well they capture and convey the
subjective experiences of individuals. Statistical measures and variables are not dimensions of a
qualitative methodology.
3. A nurse has expressed skepticism to a colleague about the value of nursing research, claiming that
nursing research has little relevance to practice. How can the nurses colleague best defend the
importance of nursing research?
