Correct Answer: C

Rationale: Rationale: Tai chi is the correct answer because it focuses on improving balance, strength, and flexibility, which are essential for preventing falls in the elderly. Tai chi's slow, controlled movements can help improve stability and reduce the risk of fractures. Summary: A (Yoga) focuses more on flexibility and relaxation, not specifically on balance and stability. B (Acupuncture) is not a physical activity and does not directly address the issue of unsteady ambulation. D (Magnet therapy) lacks scientific evidence to support its effectiveness in improving balance and preventing falls.

Correct Answer: B

Rationale: The correct answer is B because it accurately reflects the shift in focus from tuberculosis in the 1980s to the emergence of the AIDS epidemic in the 1990s in the field of nursing. Tuberculosis was a major concern in the 1980s, and the AIDS epidemic became a primary focus in the 1990s. Choice A is incorrect because it discusses preventable diseases caused by unsafe lifestyles, which is not directly related to the comparison of nursing between the two decades. Choice C is incorrect because it mentions a decrease in ambulatory services in the 1980s leading to an increase in public health nurses in the 1990s, which is not supported by the historical context of nursing during those decades. Choice D is incorrect because it suggests that the demand for advanced practice nurses increased in both the 1980s and the 1990s due to economic reasons and national health concerns, which is not specifically relevant to the comparison between nursing in the two decades.

Correct Answer: A

Rationale: The correct answer is A: aspirin order within 24 hours of discharge. This is a key clinical indicator for evaluating care of heart attack patients as aspirin is a standard treatment to prevent further cardiac events. It is crucial for patient safety and adherence to national guidelines. Choice B is incorrect as patient teaching on smoking cessation, although important, is not a direct clinical indicator for evaluating care of heart attack patients. Choice C is incorrect as beta blocker administration upon arrival is important for heart attack patients, but it is not specific to evaluating the hospital's care compared to national standards. Choice D is incorrect as employer support for stress modification is not a clinical indicator relevant to evaluating care of heart attack patients.

Correct Answer: A

Rationale: The correct answer is A because it demonstrates a proactive and thoughtful approach to decision-making. By stopping to consider the request and assessing its safety implications before accepting it based on patient acuity levels, the novice nurse is prioritizing patient safety and her own capabilities. This strategy helps her cope with the transition into practice by promoting critical thinking and confidence in her decision-making skills. Summary of why the other choices are incorrect: B: Refusing to eat anywhere but the hospital cafeteria may lead to social isolation and restrict the novice nurse's ability to engage with others outside of work. C: Ignoring coworkers' problems or staffing ideas can create a negative work environment and hinder teamwork, potentially increasing stress levels for the novice nurse. D: Focusing on winning over hostile coworkers may detract from the novice nurse's professional growth and cause unnecessary stress from seeking validation from others.

Correct Answer: C

Rationale: Step 1: A manager focuses on coordinating resources, such as people, time, and materials, to achieve organizational goals. Step 2: Coordinating resources is a key responsibility of a manager, as it involves planning, organizing, and controlling to ensure efficient operations. Step 3: Leaders, on the other hand, focus on setting a vision, inspiring and motivating others to achieve goals. Step 4: While both leaders and managers play crucial roles, the distinction lies in their primary focus and responsibilities. Step 5: Therefore, the correct answer is C, as it accurately reflects the key difference between a leader and a manager.
