Correct Answer: A

Rationale: The correct answer is A because Florence Nightingale is widely recognized as the pioneer of modern nursing research. During the Crimean War, she collected and analyzed data on patient care outcomes, demonstrating the importance of evidence-based practice in nursing. This laid the foundation for the development of nursing research as a formal discipline. Choice B is incorrect as nursing research did not start between 1900 and 1940, but rather with Nightingale's work. Choice C is incorrect because the focus of nursing research was not solely on doctorally prepared nurses but on improving patient care in general. Choice D is incorrect as the naturalistic paradigm is just one approach to research and not the starting point for nursing research.

Correct Answer: B

Rationale: The correct answer is B because the length of the NCLEX-RN exam is based on the location of testing. This is because different testing centers may have varying procedures, schedules, and regulations that can affect the overall length of the exam. The length is standardized by location to ensure fairness and consistency for all candidates. Incorrect Answers: A: The last four numbers of the candidate's social security number have no relevance to the length of the exam. C: The candidate's educational preparation may impact their readiness for the exam but does not determine the length of the exam. D: The performance of the candidate is assessed during the exam and does not determine the initial length of the exam.

Correct Answer: B

Rationale: The correct answer is B: Sunset legislation. Sunset legislation mandates that laws, including nurse practice acts, must be reviewed periodically to determine if they are still needed. If a nurse practice act is not reviewed by the specified date, it is automatically rescinded. This process ensures that laws are current and relevant. Incorrect Choices: A: Nurse review act - There is no specific law called the Nurse review act that pertains to the automatic rescinding of nurse practice acts. C: Mandatory revocation - This choice does not align with the process of automatic rescinding based on a failure to review. D: Grandfathering - Grandfathering refers to exempting individuals from new regulations based on previous circumstances, not the automatic rescinding of laws.

Correct Answer: A

Rationale: The correct answer is A: serving on interdisciplinary care teams. This is correct because as registered nurses enter the workforce, they are expected to collaborate with other healthcare professionals on interdisciplinary care teams to provide comprehensive patient care. This involves working together with professionals from different disciplines to ensure holistic and effective treatment plans. Explanation for why the other choices are incorrect: B: Being competent to work in several areas independently when dictated by patient census - While nurses may need to be versatile, the emphasis on independent work in various areas does not necessarily reflect expanded leadership responsibilities. C: Attending a meeting to plan advanced training for unlicensed assistive personnel - While important for team collaboration, attending meetings to plan training for support staff does not directly relate to expanded leadership responsibilities. D: Evaluating outcomes of care that are reported to a standing committee - While evaluating outcomes is important, it may not specifically denote expanded leadership responsibilities compared to the collaborative nature of serving on interdisciplinary care teams.

Correct Answer: D

Rationale: The correct answer is D because "safe harbor" refers to a legal provision that protects nurses when they feel unsafe accepting a staffing assignment due to lack of recent experience or competency. By invoking safe harbor, nurses can continue caring for patients while an investigation is conducted to ensure patient safety and protect the nurse's license. This process allows nurses to voice concerns without fear of reprisal. Option A is incorrect as it refers to a disaster response plan, unrelated to safe harbor. Option B is incorrect as it discusses patient care teams and infectious diseases, not safe harbor protections. Option C is incorrect because it addresses reporting violence, which is not directly related to safe harbor provisions for staffing assignments.
