A health care provider is concerned about the high number of clients with type 2 diabetes mellitus who have poor glucose control. What would be the best reference for the provider to implement evidence-based practice (EBP) in the management of this problem?

Correct Answer: B

Rationale: The correct answer is B: Current research findings. Research findings are essential for evidence-based practice (EBP) as they provide the most up-to-date and reliable information on managing type 2 diabetes mellitus. They are based on rigorous scientific methods and can guide healthcare providers in making informed decisions. Published protocols (A) may be outdated or not based on the latest evidence. Opinions of colleagues (C) vary and may not always be evidence-based. Nursing journals (D) may contain research findings, but the most direct and reliable source for current evidence is from recent research studies.

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Colleagues lacking skills in searching literature or critiquing research can hinder the nurse's efforts to increase evidence-based practice. 2. Lack of research skills can lead to difficulty in finding and evaluating relevant evidence. 3. This barrier directly impacts the nurse's ability to enhance the evidence base of practice in the agency. Summary: B: Dedication to history and tradition does not necessarily impede evidence-based practice; in fact, it can be complementary. C: While a lack of research in the clinical area is a challenge, it is not a barrier that prevents the nurse from actively seeking evidence. D: Inconsistent meta-analyses can present challenges, but they do not directly impede the nurse's efforts to increase the evidence base through literature review and critique.

Correct Answer: B

Rationale: The correct answer is B because assessing the degree to which the results relate to a specific population is essential in determining the applicability of a research article in clinical practice. This helps nurses understand if the findings can be generalized to their patient population. A: While considering the intended audience is important, it does not directly relate to the applicability of the research findings. C: Assessing the accuracy or credibility of the research is crucial, but it does not solely determine the applicability of the research to a specific population. D: Understanding the purpose of the research is important, but it may not directly address whether the results are applicable to a specific population.

Correct Answer: B

Rationale: The correct answer is B: Intervention. In a PICOT question, the intervention refers to the treatment or exposure being studied. In this case, "zinc supplementation" is the specific intervention being compared to vitamin C supplementation. The population refers to the group being studied, which is adult men in this question. The comparison is the alternative to the intervention being studied, which is vitamin C supplementation in this case. The outcome is the result or effect of the intervention, which in this question is reducing the length of respiratory viral infections over six months. So, "zinc supplementation" falls under the intervention component of the PICOT question.

Correct Answer: A

Rationale: The correct answer is A: Cochrane Library. The Cochrane Library is known for regularly updated systematic reviews. Nurses use systematic reviews to provide evidence-based practice. AHRQ (B) focuses on healthcare quality improvement, not systematic reviews. Medline with Full Text (C) is a comprehensive medical database, but it doesn't specialize in systematic reviews. CINAHL (D) is a nursing and allied health database, but it doesn't specifically focus on systematic reviews like the Cochrane Library does.
