Correct Answer: A

Rationale: The correct answer is A: federally recognized minorities. This is because Russian immigrants are considered a federally recognized minority group in the United States. By searching under this category, the nurse can find specific and relevant information about the health beliefs and practices of this particular ethnic group. Choices B, C, and D are incorrect because they do not specifically pertain to the Russian immigrant population. Marginalized populations (B) may include various minority groups but may not provide specific information about Russian immigrants. Similarly, Asian/Pacific Islander cultures (C) and Latino cultures (D) do not encompass the unique health beliefs and practices of Russian immigrants.

Correct Answer: C

Rationale: Step-by-step rationale for why choice C (case manager) is correct: 1. A case manager coordinates referrals and services for patients with complex needs, such as this patient with diabetes and dementia. 2. In this scenario, the nurse is coordinating referrals to an endocrinologist and organizing physical therapy, which aligns with the role of a case manager. 3. Case managers ensure continuity of care and facilitate communication between different healthcare providers. 4. The nurse's role in organizing follow-up care and services for the patient falls under the responsibilities of a case manager. Summary of why other choices are incorrect: A: Informatics specialist - This role focuses on managing health information systems, not coordinating referrals and services for patients. B: Educator - While education may be a component of the nurse's role, the primary focus in this scenario is on coordinating referrals and services, which is more in line with a case manager's responsibilities. D: Quality manager - Quality managers focus on ensuring healthcare services meet quality standards

Correct Answer: D

Rationale: The correct answer is D because informed consent requires the registered nurse (RN) to communicate all necessary information to the patient so they can make an informed decision. This includes explaining the procedure, potential risks, benefits, alternatives, and any other pertinent information. The RN plays a crucial role in ensuring that the patient understands the information provided before giving consent. Choices A, B, and C are incorrect because informed consent is not solely mandated by federal law, must disclose risks as well as benefits, and should not involve concealing any known risks.

Correct Answer: A

Rationale: The correct answer is A because the nurse is using evidence-based practice by conducting a literature review to determine the best practice for caring for foot ulcers. Evidence-based practice involves integrating the best available evidence with clinical expertise and patient values to make informed decisions about patient care. This nurse is ensuring that the care provided is based on current research and best practices, which can lead to better patient outcomes. Choices B, C, and D are incorrect because they do not directly relate to the nurse's action of conducting a literature review to determine best practices for foot ulcer care. Choice B mentions critical thinking but does not specifically address evidence-based practice. Choice C focuses on cost-effectiveness and level of education, which are not relevant to the nurse's evidence-based practice. Choice D refers to clinical competence, which is not the main focus of the nurse's action in this scenario.

Correct Answer: A

Rationale: The correct answer is A: experimental design. In an experimental design, the researcher manipulates one variable (aromatherapy vs. acupuncture) to observe its effect on another variable (stress). Without a control group, it is impossible to establish a baseline for comparison. A control group is essential to isolate the effects of the treatment from other variables. Quasi-experimental designs lack random assignment, surveys are used to gather data rather than test hypotheses, and meta-analyses involve combining and analyzing results from multiple studies.
