What does P < .05 mean?
The result is not significant for most nursing research, which requires more rigor.
There is a 1-in-5 chance of the result occurring again by chance alone.
The researcher is 95% confident that the result did not happen randomly.
Only 5 out of 100 nursing research studies would report this result as significant.
The Correct Answer is C
A. This statement is incorrect because a p-value less than .05 typically indicates statistical significance in nursing research.
B. This statement is incorrect because it misinterprets the meaning of p < .05. It does not mean that there is a 1-in-5 chance of the result occurring by chance alone.
C. A p-value less than .05 indicates that there is less than a 5% chance that the observed result occurred due to random chance. Therefore, the researcher can be 95% confident that the result did not happen randomly.
D. This statement is incorrect because it misinterprets the meaning of p < .05. It does not mean that only 5 out of 100 nursing research studies would report this result as significant.

Correct Answer is A
Explanation
A. A meta-analysis of recent studies focused on handwashing techniques would provide a comprehensive overview of the available evidence, synthesizing the results of multiple studies to determine the effectiveness of handwashing as an infection control measure.
B. A randomized controlled trial of a new antibiotic awaiting FDA approval would not be as relevant, as it focuses on a specific new treatment rather than established best practices.
C. A report of an exploratory study of nurses' attitudes about isolation procedures might offer insights into the practical implementation of policies but does not provide the evidence-based results needed for determining best practices.
D. A systematic review of infection control practices used throughout the 1990s would be outdated and not as applicable to current practices.
Correct Answer is A
Explanation
A. Reviewing the hospital's definition of workplace violence is important to ensure consistency with the findings of the study conducted elsewhere. This action will help the nurse manager understand how workplace violence is defined in their own hospital and whether changes need to be made based on the study's findings.
B. Developing a system for reporting workplace violence anonymously may be beneficial, but it is not directly supported by the findings of the study. It's important to first review the hospital's definition of workplace violence before implementing changes to reporting systems.
C. Repeating the study at the nurse manager's hospital may not be necessary and could be resource-intensive. Reviewing the existing literature and findings from other institutions can provide valuable insights without the need for replication.
D. Encouraging peer support among the nursing staff to report issues is a good practice, but it may not address the specific findings of the study regarding factors associated with reporting workplace violence.
