Which information is the nurse assessing when appraising the applicability of a research article?

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: 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.

Correct Answer: D

Rationale: The correct answer is D because it specifies the exact population the nurse is targeting - high school students in the rural community who smoke. This ensures the study focuses on a specific group, making it easier to design effective interventions. Choice A is too broad, not specifying the population of interest. Choice B is too general, including all community members who smoke. Choice C is also too broad, not focusing on the subgroup of interest. By choosing answer D, the nurse can tailor interventions specifically for high school students in the rural community who smoke, increasing the study's relevance and potential impact.

Correct Answer: C

Rationale: During the evaluation phase of EBDM, the nurse would determine the effectiveness of the plan. This involves assessing whether the implemented plan achieved the desired outcomes based on the evidence gathered. This step is crucial in determining the success of the decision-making process and informing future actions. Choice A (Carrying out the proposed plan) is incorrect as it pertains to the implementation phase, not evaluation. Choice B (Deciding if the evidence is applicable to the population) is incorrect as this is part of the critical appraisal phase, not evaluation. Choice D (Compiling the data) is incorrect as it is typically done in the earlier stages of EBDM to gather evidence, not during the evaluation phase.

Correct Answer: C

Rationale: During the Exposure Assessment stage, the public health team quantifies the extent, frequency, and duration of contact of the community with the toxic chemicals. This is crucial to determine the potential health risks posed by the exposure. By quantifying these factors, the team can assess the level of risk to the community accurately. Choice A is incorrect because it focuses on identifying negative outcomes rather than quantifying exposure levels. Choice B is incorrect as it relates exposure amount to health outcomes, which is more relevant in the Dose-Response Assessment stage. Choice D is incorrect as it pertains to the Absorption, Distribution, Metabolism, and Excretion stage, which comes after exposure assessment. In summary, choice C is correct as it directly aligns with the purpose of Exposure Assessment, while the other choices are either not relevant to this stage or belong to different stages of the risk assessment process.
