Correct Answer: A

Rationale: The correct answer is A: Genetic research. Telomere shortening is primarily based on the theory of cellular senescence, which is related to genetic research. Telomeres are protective caps at the end of chromosomes that shorten with each cell division. Genetic research has shown that telomere shortening is associated with aging and age-related diseases. Caloric restriction, oxidative stress, and cross-link theories of aging are not directly linked to telomere shortening. Caloric restriction focuses on extending lifespan by reducing calorie intake, oxidative stress theory suggests that aging is caused by cumulative damage from reactive oxygen species, and cross-link theory emphasizes the accumulation of non-reversible bonds between molecules as a cause of aging.

Correct Answer: D

Rationale: The correct answer is D because pursed lip breathing helps prevent airway collapse by maintaining positive pressure in the airways, reduces anxiety by promoting relaxation, and enhances effective breathing by improving oxygen exchange. Choice A is incorrect as pursed lip breathing does not directly prevent the build-up of secretions. Choice B is incorrect as comfort is not the primary purpose of pursed lip breathing. Choice C is incorrect as while pursed lip breathing can improve respiratory muscle function, its primary benefit lies in preventing airway collapse, reducing anxiety, and promoting effective breathing.

Correct Answer: B

Rationale: The correct answer is B: Dementia. Older adults often experience cognitive decline, memory loss, and behavioral changes that can be mistaken for symptoms of depression. Dementia is a common condition in the elderly that can be misdiagnosed due to overlapping symptoms such as apathy, social withdrawal, and changes in sleep patterns. Chronic fatigue syndrome (A), anemia (C), and sleep apnea (D) may also present with symptoms of fatigue and sleep disturbances, but they are less likely to be confused with depression in older adults compared to dementia.

Correct Answer: A

Rationale: The correct answer is A: Alzheimer's disease. It is the most common type of dementia in older adults, accounting for around 60-80% of cases. Alzheimer's is characterized by the presence of beta-amyloid plaques and tau protein tangles in the brain, leading to memory loss and cognitive decline. Vascular dementia (B) is caused by impaired blood flow to the brain, Lewy body dementia (C) is characterized by abnormal protein deposits in the brain, and Frontotemporal dementia (D) affects the frontal and temporal lobes of the brain, leading to changes in behavior and personality. However, in older adults, Alzheimer's disease is the most prevalent form of dementia due to its widespread impact on memory and cognition.

Correct Answer: B

Rationale: The correct answer is B: John Hartford Foundation. The John Hartford Foundation is known for its significant contributions to the field of gerontological nursing through funding research, education, and initiatives to improve care for older adults. The foundation has supported the development of gerontological nursing programs and resources, making it a key influencer in advancing the specialty. Explanation for other choices: A: American Association of Retired Persons (AARP) primarily focuses on advocacy and support for older adults but does not have a direct influence on the specialty of gerontological nursing. C: Medicare is a federal health insurance program for individuals aged 65 and older, but it does not specifically impact the development of gerontological nursing as an organization. D: Mutual of Omaha Insurance is an insurance company and does not have a direct role in shaping the field of gerontological nursing.
