Correct Answer: B

Rationale: The correct answer is B: randomization. Randomization helps ensure improved generalizability by reducing bias and increasing the likelihood that the sample is representative of the population. In this scenario, choosing every third person from an alphabetical list introduces a systematic bias and may not represent the entire population accurately. Triangulation involves using multiple methods or data sources to validate findings, which is not applicable here. Informed consent is a necessary ethical consideration but does not directly impact generalizability. A meta-analysis approach involves combining and analyzing data from multiple studies, which is not relevant to the sampling method in this scenario. Thus, randomization is the best choice to improve generalizability in this study.

Correct Answer: B

Rationale: The correct answer is B: autonomy. Autonomy refers to respecting the right of individuals to make their own decisions about their healthcare. In this scenario, the family's request to honor the terminally ill mother's advance directives aligns with the principle of autonomy as it acknowledges her right to make decisions about her own care. Accountability (A) pertains to taking responsibility for one's actions, nonmaleficence (C) involves avoiding harm, and veracity (D) refers to truthfulness. While these principles are important in healthcare, in this specific case, autonomy takes precedence as it respects the patient's wishes.

Correct Answer: A

Rationale: The correct answer is A: beneficence. Beneficence refers to the ethical principle of maximizing benefits and minimizing harm in research. In this scenario, the researcher calculated the risk-to-benefit ratio and concluded that no harmful effects were associated with the survey of college sophomores. By considering the well-being of the research participants and ensuring that the benefits outweigh any potential risks, the researcher demonstrated the application of beneficence. Summary: Choice A is correct because it aligns with the ethical principle of beneficence in research. Choices B, C, and D are incorrect as they do not directly relate to the consideration of risks and benefits in research involving human participants.

Correct Answer: A

Rationale: The correct answer is A: Environment. Nursing theory often includes the concept of environment, which encompasses physical, social, and psychological factors influencing a patient's health. This concept helps nurses understand the context in which care is provided and how it impacts health outcomes. Incorrect choices: B: Health - While health is a fundamental aspect of nursing, it is not specific to nursing theory concepts. C: Nursing - This is a broad term encompassing the profession itself, not a specific concept within nursing theory. D: Relevance - This term is not directly associated with nursing theory concepts and does not provide a framework for understanding nursing practice.

Correct Answer: D

Rationale: The correct answer is D because the RN must have knowledge of laws and regulations governing nursing practice, including those that have unclear boundaries for UAP. This is crucial to ensure safe and effective delegation. Option A is incorrect because the nurse practice act typically does not define UAP roles. Option B is incorrect as delegation also requires assessing competency, not just training. Option C is incorrect as supervision is necessary regardless of the task's routine nature. The correct answer emphasizes the importance of legal knowledge for proper delegation.
