Correct Answer: A

Rationale: Correct Answer: A Rationale: The correct answer is A because statistics show that currently, less than half of all registered nurses work in hospital settings, with the majority working in community, home health, long-term care, and other non-hospital settings. This information is supported by recent workforce studies and trends in nursing practice. Summary of other choices: B: The average age for an RN is not necessarily 50 years, as there is a wide range of ages among RNs, with many entering the profession at younger ages. C: Approximately 25% of RNs are male, which is a significant proportion but does not encompass the majority of the nursing workforce. D: While the number of RNs with bachelor's degrees is increasing, the majority of RNs still do not hold a bachelor's degree as their highest level of education.

Correct Answer: A

Rationale: Step-by-step rationale for why answer A is correct: 1. Federal legislation such as the Affordable Care Act has expanded Medicaid coverage and provided subsidies for health insurance. 2. This legislation has helped reduce the number of minorities lacking health insurance. 3. Consequently, fewer minorities than members of the general population now lack health insurance. 4. Therefore, the statement that federal legislation has resulted in fewer minorities lacking health insurance is true. Summary of why other choices are incorrect: B. This choice incorrectly attributes the lack of seeking health care by minorities solely to higher costs and lower wages, overlooking the impact of legislation. C. This choice makes a sweeping generalization about Mexican Americans without considering the broader context of health care access for minorities. D. This choice relies on stereotypes about Asians and does not take into account the complexities of the health care system and insurance coverage.

Correct Answer: B

Rationale: The correct answer is B: decontamination. Decontamination is the process of removing harmful chemicals from equipment and supplies to prevent further exposure and contamination. In this scenario, the disaster medical assistance team is working to contain contaminants first and then proceed with decontamination to ensure the safety of personnel. Containment (choice A) refers to preventing the spread of contaminants, not removing them. Triage (choice C) is the process of prioritizing patients based on the severity of their injuries, not removing chemicals. Scene assessment (choice D) involves evaluating the situation to determine the extent of the disaster, not the removal of harmful chemicals.

Correct Answer: A

Rationale: The correct answer is A because it specifies a measurable and achievable goal related to improving cardiac function through physical activities. It follows the SMART criteria (Specific, Measurable, Achievable, Relevant, Time-bound). Option B does not provide a specific outcome, while Option C focuses on pharmaceutical approaches rather than outcomes. Option D is unrelated to the goal of improving outcomes for heart failure patients. Thus, option A is the most appropriate choice for a well-defined and relevant outcome for the care of heart failure patients.

Correct Answer: A

Rationale: The correct answer is A: Articulation. This nursing model is referred to as the "class without walls" because it focuses on seamless academic progression and collaboration between educational institutions. Articulation promotes a smooth transition of nursing students from one level of education to another, eliminating barriers and creating a cohesive learning experience. The other choices (B, C, D) do not specifically emphasize the concept of breaking down walls or barriers in education like the Articulation model does.
