What does P <.05 mean?
There is a 1-in-5 chance of the result occurring again by chance alone.
The result is not significant for most nursing research, which requires more rigor.
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
Choice A rationale:
P < .05 does not indicate a specific probability of the result occurring again by chance alone (e.g., 1-in-5 chance). Instead, it signifies that the result is statistically significant at the 0.05 level.
Choice B rationale:
While nursing research often requires rigorous standards, P < .05 represents a common threshold for statistical significance in many research studies. It does not indicate that the result is not significant for nursing research.
Choice C rationale:
This is the correct answer. P < .05 means that the researcher is 95% confident that the result did not occur randomly. In other words, there is a 95% probability that the observed result is not due to chance but is related to the variables being studied.
Choice D rationale:
P < .05 does not imply that only 5 out of 100 nursing research studies would report this result as significant. It signifies a specific level of confidence in the result's significance, not its frequency in research studies.

Correct Answer is C
Explanation
Choice A rationale:
Evaluate sleep quality and depression of all pregnant women. Rationale: While it's important to assess the sleep quality and mental health of pregnant women, implementing this intervention for all pregnant women based solely on the study findings may not be efficient or necessary. It's more appropriate to target interventions to those at higher risk, such as those showing signs of poor sleep quality, stress, or depression.
Choice B rationale:
Replicate the study using the clinic's population. Rationale: Replicating the study may not be necessary if the clinic's population and context are similar to those of the study that was conducted. Implementing an intervention based on the existing evidence is a more practical approach.
Choice C rationale:
Develop a counseling program for depressed pregnant women. Rationale: This intervention is aligned with the study findings, which indicated that sleep quality of pregnant women was related to stress and depression. Targeting counseling for depressed pregnant women is a focused and evidence-based approach.
Choice D rationale:
Screen all women for poor sleep quality. Rationale: While screening for poor sleep quality is important, implementing it for all women, including those who are not pregnant, may not be relevant or efficient.
Correct Answer is A
Explanation
Choice A rationale:
Identify the primary attitudinal factors that the authors described as protecting against smoking. Rationale: This action is most important because it directly addresses the nurse's objective of preparing an anti-smoking campaign for junior high school students. Understanding the primary attitudinal factors that protect against smoking among youth populations can inform the development of effective interventions to reduce smoking in this specific demographic.
Choice B rationale:
Contact the authors and ask for their assistance in developing a curriculum for the anti-smoking campaign. Rationale: While collaborating with the authors could potentially provide valuable insights, the immediate priority is to identify the key attitudinal factors described in the research article. This information forms the foundation for the anti-smoking campaign's content and strategies.
Choice C rationale:
Review the article to determine if institutional review board approval was obtained prior to conducting the study. Rationale: Institutional review board (IRB) approval is important for ethical research, but it is not the nurse's primary concern at this stage. The focus should be on gathering relevant information to inform the campaign.
Choice D rationale:
Determine if any of the studies reviewed by the authors used a junior high school population. Rationale: While understanding the populations studied in the research articles is useful for context, it is not as critical as identifying the specific attitudinal factors that protect against smoking among youth populations, which can directly inform the campaign's development.
