Rationale: The correct answer is A: Safe staffing. Safe staffing is a critical issue in nursing today due to its impact on patient outcomes and nurse well-being. While low workloads (choice B) may seem beneficial, they can also indicate understaffing, leading to burnout and compromising patient care. Increasing professional autonomy (choice C) is generally viewed positively as it empowers nurses, and improving salaries (choice D) is important but may not directly address patient safety concerns related to staffing levels.

Correct Answer: B

Rationale: The correct answer is B because a new model for health care in the future should focus on promoting a healthy environment. This includes initiatives such as green buildings and reducing pollution to improve overall health outcomes. Choice A, community-centered care, is important but not the primary focus when considering the future of healthcare. Choice C, accessible and affordable care, is crucial but does not directly address the need for a healthy environment. Choice D, a focus on local health concerns, is relevant but not as comprehensive as promoting a healthy environment in shaping the future of healthcare.

Correct Answer: B

Rationale: Engaging in conversations about healthcare issues with a wide audience, including legislators, is a powerful way for a nurse to exert leadership and support the nursing profession. This action helps raise awareness, advocate for nursing-related matters, and contribute to positive changes in healthcare policies. Choice A, joining a local professional organization, is beneficial but may not have the same broad impact as engaging in public discourse. Choice C, registering to vote, is important for civic engagement but does not directly relate to exerting leadership in supporting the nursing profession. Choice D, learning about the healthcare system, is valuable for personal development but does not directly address exerting leadership in supporting the nursing profession.

Correct Answer: C

Rationale: Osgood-Schlatter disease is a condition that commonly affects adolescents who are physically active, especially during growth spurts. It is caused by overuse of the knee, leading to inflammation of the patellar ligament at the tibial tuberosity. The repetitive stress on the growth plate during activities like running and jumping can trigger this condition. Therefore, an adolescent who is physically active and the captain of their soccer team is most at risk for Osgood-Schlatter disease. Choices A, B, and D are not at high risk for this condition as it is primarily seen in active adolescents.
