Researchers hypothesize that most super-centenarians survive and are in good health due to which of the following factors?

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: A

Rationale: The correct answer is A: Role theory. Role theory suggests that individuals continue to seek fulfilling roles and activities in older age to maintain a sense of purpose and identity. In this scenario, the older woman's transition from a career as a school principal to volunteering at the library aligns with the idea of seeking meaningful roles. B: Disengagement theory posits that older adults withdraw from society as they age, which contradicts the woman's active engagement in volunteering. C: Age-stratification theory focuses on how age influences opportunities and constraints within society, not on individual choices like volunteering. D: Social exchange theory emphasizes reciprocal relationships and benefits gained from social interactions, which is not the primary focus in this scenario.

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: A

Rationale: The correct answer is A: The National Gerontological Nursing Association (NGNA). NGNA welcomes nurses from all educational backgrounds, focusing on gerontological nursing practice. The other choices have specific focuses: B is for nurse practitioners, C is for directors of nursing administration, and D is for professionals in the field of aging. NGNA's inclusivity makes it the correct choice for nurses from all educational backgrounds interested in gerontological nursing.

Correct Answer: C

Rationale: The correct answer is C: Certified gerontological nurse. This nurse has specialized knowledge and training in caring for elderly patients, aligning with the nursing home's focus on eldercare standards. Certification demonstrates expertise in gerontological nursing. A: A nurse from a certified college may not necessarily have specialized training in gerontological nursing. B: Experience is valuable, but without specific gerontological training, the nurse may lack the specialized skills required for eldercare. D: A gerontological nurse practitioner has advanced training, but for direct patient care in a nursing home setting, a certified gerontological nurse may be a better fit.
