Correct Answer: C

Rationale: The correct answer is C because it states that the exact cause of super-centenarians' longevity and good health is not known. This acknowledges the uncertainty and complexity of the situation, highlighting the need for further research and understanding. Explanation for why the other choices are incorrect: A: Genetic makeup alone may not fully explain super-centenarians' survival, as there are likely additional factors involved. B: Living in wealthier areas does not guarantee longevity or good health, as there are many other factors at play. D: While quality medical care and improved social conditions can contribute to health, they are not the sole reasons for super-centenarians' exceptional longevity.

Correct Answer: B

Rationale: The correct answer is B because using large size fonts on written material is important for elderly individuals in assisted living facilities who may have visual impairments. This accommodation ensures that the residents can easily read and understand the information being presented. This is crucial for effective communication and engagement in the educational program. A: While using simple language is generally beneficial, the primary concern for this specific population is visual accessibility rather than language complexity. C: Providing the program in a quiet area is important for minimizing distractions, but it is not as critical as ensuring the residents can read the material. D: While building on prior knowledge is a good practice in teaching, it is secondary to ensuring that the information is visually accessible to the residents.

Correct Answer: B

Rationale: The correct answer is B: Providing palliative care focused on symptom management and comfort. This is the most appropriate intervention for an older adult with advanced heart failure as it prioritizes quality of life by focusing on alleviating symptoms and ensuring comfort. High-dose diuretics (choice A) may lead to electrolyte imbalances and worsen the patient's condition. Initiating aggressive cardiac surgery (choice C) may be too risky and invasive for an older adult with advanced heart failure. Enforcing strict bed rest (choice D) can lead to deconditioning and muscle wasting, further compromising the patient's quality of life.

Correct Answer: A

Rationale: The correct answer is A because it accurately reflects the multifactorial nature of diabetes in older adults. Age-related changes, coupled with lifestyle factors like poor diet and lack of exercise, contribute to the high incidence of diabetes in this population. This statement acknowledges the complexity of diabetes in older adults. B is incorrect because while nurses should have knowledge about diabetes in older adults, the statement does not specifically address the multifactorial nature of the disease in this population. C is incorrect because ethnicity can indeed play a role in diabetes risk and should not be dismissed outright. D is incorrect because the development of diabetes is not considered a normal age-related change; it is a medical condition that can be influenced by various factors.

Correct Answer: C

Rationale: The correct answer is C because consistent routines and environmental modifications have been shown to be the most effective approach in reducing agitation and aggression in older adults with dementia. This approach focuses on providing structure and familiarity, which can help decrease confusion and anxiety in individuals with dementia. Physical restraints (A) are not recommended as they can lead to further agitation and pose risks of injury. Increased sedation with antipsychotics (B) should be used as a last resort due to potential side effects and risks. Ignoring the behavior (D) is not appropriate as it can exacerbate the situation and lead to further distress for the individual.
