After finding several studies related to the clinical problem, a nurse knows the studies must be evaluated. For the studies to be considered convincing, they should ideally be:

Correct Answer: B

Rationale: The correct answer is B because multiple high-quality studies with large sample sizes and consistent findings provide strong evidence to support clinical decisions. Such studies reduce bias and increase generalizability. Choice A is incorrect as federal support does not guarantee study quality. Choice C lacks emphasis on study quality and consistency. Choice D is not always necessary for convincing evidence as observational studies can also provide valuable insights.

Correct Answer: B

Rationale: The correct answer is B because increasing noncompetitive physical activity programs in schools aligns with primary prevention efforts. By implementing policies that promote regular exercise for all students, the school nurse can proactively address wellness and weight control issues. This approach targets the entire student population, not just overweight children, and encourages healthy habits for all. A: Developing individualized exercise programs for overweight children is more focused on secondary prevention rather than primary prevention. It addresses existing weight issues rather than preventing them. C: Monitoring body mass index in children focuses on early detection rather than primary prevention. It does not address the broader population or promote general wellness. D: Notifying parents about their child's weight in comparison to national norms is important but does not actively promote primary prevention through school-wide initiatives like increased physical activity programs.

Correct Answer: B

Rationale: The correct answer is B because reviewing outcomes of clinical trials provides scientific evidence on the effectiveness of treatments for the new infectious disease. Clinical trials follow a rigorous methodology that evaluates the safety and efficacy of interventions. This helps the nurse make informed decisions based on proven results. Choice A is incorrect because policies and procedures may not always be evidence-based or updated to address a new infectious disease outbreak. Choice C is incorrect as nursing textbooks may not have the most current information on a new disease. Choice D is incorrect because information obtained from the internet may not be reliable or evidence-based.

Correct Answer: A

Rationale: The correct answer is A because colleagues who lack skills in literature search and research critique can hinder a nurse's ability to increase the evidence base in practice. This is because collaboration and knowledge-sharing are essential in evidence-based practice. Choice B is incorrect as dedication to history and tradition does not necessarily impede evidence-based practice. Choice C is incorrect because emphasis on conformity does not directly relate to the nurse's decision to increase evidence base. Choice D is incorrect as having extensive experience in research interpretation should actually support, rather than interfere with, improving evidence-based practice.

Correct Answer: C

Rationale: The correct answer is C: The opportunity for the women to practice what they learned. This is crucial because practical application reinforces learning. By allowing the women to practice breast self-examination techniques during the session, they can gain confidence and ensure they understand the process correctly. This hands-on approach enhances retention and ensures the information is effectively internalized. Choice A (Lots of time for audience members to ask questions and clarify the information) is important but not as critical as providing the opportunity for practice. While addressing questions is beneficial, practical application solidifies learning. Choice B (An explanation of why culturally appropriate images are more acceptable) is relevant for engaging the audience but not as essential as hands-on practice. Cultural sensitivity is important but does not directly impact the effectiveness of the teaching session. Choice D (The use of simple language instead of printed material in case the women could not read) is also important for accessibility but does not address the core issue of reinforcing learning through practice. Simplified language aids comprehension but
