A researcher is assessing the reliability of a new instrument that was constructed to measure pain perception following cardiac catheterization.
The Cronbach's alpha obtained from a pilot study of the tool was 0.35. Which evaluation does the alpha value indicate?
There is a moderate amount of inter-rater reliability for this tool.
The instrument needs revision due to a lack of internal consistency.
The tool will consistently measure pain perception in clients.
Numerous inverse relationships exist among items on the scale.
The Correct Answer is B
Choice A rationale:
Cronbach's alpha is a measure of internal consistency, not inter-rater reliability. Inter-rater reliability assesses the degree of agreement between different raters or observers, which is not applicable in this context.
Choice B rationale:
This is the correct answer. A Cronbach's alpha value of 0.35 indicates poor internal consistency for the instrument. In other words, the items in the tool do not consistently measure the same underlying construct (pain perception). A low alpha value suggests that the items in the instrument may not be reliably measuring the intended concept and that revision may be necessary to improve the tool's consistency.
Choice C rationale:
The statement "The tool will consistently measure pain perception in clients" is not supported by the low Cronbach's alpha value of 0.35. A low alpha suggests that the tool does not demonstrate consistent measurement of pain perception.
Choice D rationale:
Cronbach's alpha does not provide information about the presence of inverse relationships among items on the scale. It assesses internal consistency, which is about the degree to which items on the scale are interrelated and measure the same construct. A low alpha indicates poor internal consistency but does not specifically indicate the presence of inverse relationships.

Correct Answer is D
Explanation
Choice A rationale:
Interviewing clients to determine if they remembered concepts taught preoperatively does not represent the first step in identifying previous research studies. It focuses on assessing the retention of teaching rather than reviewing existing literature.
Choice B rationale:
Reading full-text articles in nursing journals about designing client teaching sessions is valuable but not the first step in identifying previous research studies. It focuses on teaching session design rather than the literature review process.
Choice C rationale:
Asking orthopedic surgeons about topics to cover preoperatively with clients is a form of expert consultation but does not represent the first step in identifying previous research studies. It involves seeking expert input rather than reviewing existing literature.
Choice D rationale:
This is the correct answer. Reviewing research abstracts on preoperative teaching with a similar client population is typically the first step in conducting a literature review. It allows the nurse to identify relevant research studies that have investigated the effectiveness of preoperative teaching in a similar context.
Correct Answer is B
Explanation
Choice A rationale:
Conclusions in a research report typically summarize the key findings and interpretations of the study. While the statement mentions organizational attributes associated with a professional nursing practice environment, it appears to be background information rather than a study-specific conclusion.
Choice B rationale:
This is the correct answer. The statement pertains to the literature review section of the research report. It introduces and discusses previous research (magnet hospital studies) and their findings related to organizational attributes associated with a professional nursing practice environment. This information sets the context for the study and supports the rationale for the research.
Choice C rationale:
Methodology sections in research reports typically describe the study's design, data collection methods, and statistical analysis procedures. The statement does not belong in this section as it discusses previous research rather than the study's methods.
Choice D rationale:
Findings sections in research reports present the results of the study and the data obtained from the research participants. The statement is not a direct finding of the study but rather background information about prior research.
