The practice of nurses, nursing students, and faculty is affected by demographic changes due to:

Correct Answer: B

Rationale: The correct answer is B: increasing numbers of obese children and adults. This demographic change directly impacts the practice of nurses by requiring specialized care and interventions for obesity-related health issues. Nurses need to be equipped to address the unique needs of obese patients. A is incorrect because the growing percentage of adults ages 50 to 55 years does not necessarily impact nursing practice significantly. C is incorrect as changes in family structure do not directly affect nursing care. D is incorrect because social programs alone cannot eliminate poverty entirely and poverty remains a significant factor affecting healthcare access and outcomes.

Correct Answer: A

Rationale: The correct answer is A: Rogers' science of unitary human beings. Martha Rogers' theory emphasizes the interconnectedness of humans and the environment, showing how individuals are unified with their surroundings. This theory serves as the foundation for nursing science by focusing on the holistic nature of individuals and their environment, aligning with the core principles of nursing practice. Rogers' theory guides nurses in understanding the interconnectedness of human beings and their environment, shaping the way nursing care is delivered. Summary of other choices: B: Nightingale's theory of practice focuses on environmental factors and cleanliness in healthcare settings, but it does not provide the comprehensive framework for nursing science. C: Watson's theory of human caring emphasizes the importance of caring in nursing, but it does not serve as the fundamental basis for nursing science. D: King's theory of goal attainment emphasizes goal setting and achieving outcomes in nursing care, but it does not lay the foundational principles for nursing science.

Correct Answer: D

Rationale: The correct answer is D: National Disaster Medical System (NDMS). This system is designed to provide medical care during disasters, including addressing mental health needs like posttraumatic stress syndrome in victims and compassion fatigue in care providers. NDMS coordinates federal medical response resources and personnel to support communities during disasters. A: Strategic National Stockpile focuses on providing medicines, vaccines, and medical supplies, but does not directly address mental health needs or provide medical care. B: Metropolitan Medical Response System (MMRS) focuses on local response capabilities for mass casualty incidents, but does not have the same scope as NDMS in providing comprehensive medical care. C: Commissioned Corps Readiness Force is a team of healthcare professionals within the U.S. Public Health Service, but it is not specifically designated for disaster medical response like NDMS.

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Understanding one's values: It is essential for the nurse to know their own values and how these impact their nursing practice. 2. Relationship to beliefs and nursing philosophy: Knowing one's values helps align with the ethical principles and philosophy of nursing. 3. Ethical decision-making: By understanding personal values, the nurse can make informed and ethical decisions in the care of the client. 4. Professional integrity: Being aware of personal values promotes professional integrity and ensures the nurse's actions are in line with ethical standards. Summary: - Option B is incorrect as the focus should be on understanding and reconciling one's values rather than eliminating them. - Option C is incorrect as ignoring one's values can lead to ethical dilemmas and compromise the quality of care. - Option D is incorrect as values are subject to change and can be influenced by various factors, including professional experiences and education.

Correct Answer: A

Rationale: The correct answer is A because Medicare covers hospital stays for individuals aged 65 and older, which would include a 70-year-old client. Choice B is incorrect because Medicare typically covers dialysis for individuals with end-stage renal disease, not nursing home costs. Choice C is incorrect because Medicare does not typically cover rehabilitation care for individuals under 65. Choice D is incorrect because AFDC is a separate program from Medicare that provides assistance for low-income families, and prescription costs for the young mother would likely be covered under a different program.
