Questions and Answers

Within the context of advanced nursing research, what is the most critical distinction between EMBASE and CINAHL databases in guiding a comprehensive literature review focused on geriatric palliative care?

CINAHL offers specialized indexing related to nursing practice, ethical considerations, and psychosocial aspects of palliative care, which are less emphasized in EMBASE's pharmacological and biomedical focus. (correct)
CINAHL provides superior coverage of allied health professions and rehabilitation studies relevant to palliative care, while EMBASE prioritizes biomedical and pharmacological aspects.
EMBASE indexes a broader range of international pharmaceutical literature, whereas CINAHL focuses exclusively on North American nursing interventions.
EMBASE employs MeSH (Medical Subject Headings) for indexing, offering a more granular search capability for pharmacological interventions compared to CINAHL's use of keyword-based indexing.

In the context of a meta-analysis on the effectiveness of mindfulness-based interventions for chronic pain management, what methodological criterion would be MOST crucial when evaluating the abstracts of potential studies for inclusion?

The abstract includes a detailed discussion of potential confounding variables and limitations affecting the generalizability of findings.
The abstract explicitly states adherence to the PRISMA guidelines for systematic reviews.
The abstract clearly delineates the specific mindfulness intervention protocol, control group characteristics, and primary outcome measures regarding pain reduction. (correct)
The abstract reports statistically significant improvements in pain scores using intention-to-treat analysis.

Considering the principles of a rigorous and integrative literature review, what strategic approach best synthesizes information from disparate studies examining the impact of nurse staffing ratios on patient mortality?

Apply a vote-counting method, tallying the number of studies reporting positive, negative, or neutral effects of nurse staffing ratios on patient mortality to determine the overall direction of the evidence.
Employ a thematic analysis, focusing on recurrent keywords and phrases across studies to identify common themes and areas of consensus.
Utilize a framework synthesis approach, developing an initial conceptual model based on a priori theoretical perspectives and iteratively refining it based on emerging evidence from the literature. (correct)
Conduct a narrative synthesis, prioritizing studies with the largest sample sizes and statistically significant findings to establish a clear causal relationship.
