The nurse who works in a diabetes management clinic reviews several research articles to determine if individual or group education is the most effective teaching method for the clinic's clients.
Which study provides the best evidence?
A descriptive study that found a positive link between individual teaching and blood glucose levels.
A qualitative study that interviewed subjects and found that they preferred individual education.
A cost analysis study that determined group education was less costly than individual education.
A randomized controlled trial that concluded individual and group education achieve similar results.
The Correct Answer is D
Choice D rationale:
A randomized controlled trial that concluded individual and group education achieve similar results. Rationale: Randomized controlled trials (RCTs) are considered the gold standard for assessing the effectiveness of interventions. In this case, an RCT concluded that individual and group education achieve similar results, providing strong evidence for decision-making in the diabetes management clinic.
Choice A rationale:
A descriptive study that found a positive link between individual teaching and blood glucose levels. Rationale: Descriptive studies provide valuable information but do not establish causal relationships. A positive link between individual teaching and blood glucose levels may suggest an association but does not necessarily demonstrate effectiveness.
Choice B rationale:
A qualitative study that interviewed subjects and found that they preferred individual education. Rationale: Qualitative studies explore preferences and experiences but do not typically provide evidence of effectiveness in terms of health outcomes or clinical practice.
Choice C rationale:
A cost analysis study that determined group education was less costly than individual education. Rationale: Cost analysis studies focus on economic aspects and cost-effectiveness but may not address clinical effectiveness or outcomes. The best evidence for clinical decision-making typically comes from RCTs.

Correct Answer is D,B,C,A
Explanation
Choice A rationale:
The analysis of findings typically comes after the discussion section in a research report. In the analysis section, the researcher presents and interprets the results of the study.
Choice B rationale:
The methodology section should follow the review of the literature as it provides a detailed description of the research methods and design used in the study. Readers need to understand the context and background from the literature review before delving into the methodology.
Choice C rationale:
The discussion section should come after the methodology section. In the discussion, the researcher analyzes and interprets the results, compares them to existing literature, and discusses their implications.
Choice D rationale:
The review of the literature should be the first section of the research report, providing an overview of relevant prior research and setting the context for the study. It helps readers understand the existing knowledge in the field before moving on to the study's methodology, findings, and discussion.
Correct Answer is D
Explanation
Choice A rationale:
Postponing the study for six months would not necessarily resolve the impact of the 9/11 events on the study's participants. It may also introduce other confounding factors related to the delay.
Choice B rationale:
Instructing study subjects to disregard their feelings about 9/11 may not be feasible or effective, as traumatic events can have a lasting impact on individuals' psychological well-being and attitudes.
Choice C rationale:
Abandoning the study due to the 9/11 events may not be necessary, but it is essential to acknowledge and address the potential influence of external events on the study's internal validity.
Choice D rationale:
This is the correct answer. The authors should have reported the 9/11 events as a potential threat to the study's internal validity, as they could have introduced confounding variables or influenced the participants' responses. By acknowledging this, researchers can provide transparency about potential limitations and their efforts to control for them.
