Correct Answer: A

Rationale: The correct answer is A: Gerontological nursing certification indicates that a nurse has advanced knowledge and skills specifically related to the care of older adults. This is accurate because gerontological nursing certification is a voluntary certification that demonstrates a nurse's specialized expertise in caring for the elderly population. Nurses who obtain this certification have undergone additional training and education in gerontological nursing, making them more competent in addressing the unique needs of older adults. Choices B, C, and D are incorrect: B: All nurses in long-term care must obtain gerontological certification after completing their initial training - This is false as gerontological certification is not mandatory for all nurses in long-term care. C: Certification in gerontology is only necessary for nurses working in rehabilitation centers - This is incorrect as gerontological certification is beneficial for nurses caring for older adults in various settings, not just rehabilitation centers. D: Only nurses with a master's degree can achieve certification in gerontology - This is not true as nurses with

Correct Answer: C

Rationale: The correct answer is C: Age-stratification theory. This theory suggests that age is a powerful determinant of social organization. In the given scenario, the retirement community is structured based on age groups, indicating stratification by age. This separation aligns with the concept of age-based social hierarchies and differing opportunities and resources based on age. Choice A (Role theory) focuses on how individuals adapt to social roles as they age, which is not directly reflected in the scenario. Choice B (Disengagement theory) posits that aging individuals withdraw from societal roles, which is not evident in the active engagement of residents in different age-specific communities. Choice D (Social exchange theory) emphasizes the relationships individuals form based on rewards and costs, which is not the primary focus in the scenario compared to the age-based stratification.

Correct Answer: A

Rationale: The correct answer is A: Promoting wellness. Providing information about diet and exercise for a healthy diabetic client falls under promoting wellness because it focuses on proactive measures to maintain health and prevent complications. It aims to empower the client to make healthy lifestyle choices. B: Preventing illness is not the best description as the client is already diabetic, so the focus is on managing the condition rather than solely preventing it. C: Treating disease is not accurate because the client is already diabetic and the goal is not to treat the disease, but rather manage it effectively. D: Restoring health is not applicable in this scenario as the client is not in a state of compromised health that needs to be restored.

Correct Answer: B

Rationale: The correct answer, B, is the primary role of the gerontological nurse when providing end-of-life care for a terminally ill older adult. This choice emphasizes the importance of pain management, comfort care, and preserving the patient's dignity. The nurse's focus should be on enhancing the quality of life and ensuring the patient's comfort rather than pursuing aggressive curative treatments (A). Administering sedatives (C) should be based on individual needs and preferences, not as a blanket approach. While family involvement is crucial, the nurse should still advocate for the patient's autonomy and preferences, rather than solely relying on family decisions (D).

Correct Answer: D

Rationale: The correct answer is D: Confusion or cognitive decline. In older adults, dehydration can manifest differently than in younger populations. Cognitive decline is a key sign of dehydration in older adults due to the brain being more sensitive to fluid loss. Dehydration can lead to confusion, disorientation, and impaired cognitive function in older individuals. Dark-colored urine (A) is a common sign of dehydration in all age groups. Increased thirst (B) is a general sign of dehydration but may not be as prominent in older adults due to decreased thirst sensation. Dry mouth and skin (C) are also common signs of dehydration but may not be as reliable indicators in older adults compared to cognitive changes.
