While testing the vision of an elderly client, the nurse finds that the client has decreased ability to accommodate (presbyopia). Which clinical implication would the nurse recognize?

Correct Answer: B

Rationale: The correct answer is B: Difficulty reading small print and decreased ability to focus on objects at varying distances. As people age, the lens of the eye becomes less flexible, leading to presbyopia, which results in difficulty seeing close objects clearly. This explains the client's decreased ability to accommodate. This choice is correct because presbyopia specifically affects near vision, making it harder to read small print and focus on objects up close. A: Blurring of vision due to increased intraocular pressure - This choice is incorrect because presbyopia is not related to increased intraocular pressure. C: Narrowing of field of vision-loss of peripheral vision - This choice is incorrect because presbyopia does not affect peripheral vision; it specifically impacts near vision. D: Sensitivity to light (photophobia) - This choice is incorrect because presbyopia does not cause sensitivity to light; it is solely related to difficulty in focusing on near objects.

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: A

Rationale: The correct answer is A, the Gerontological Society of America, because it includes members from various disciplines such as sociology, psychology, biology, and medicine. This interdisciplinary approach allows for a holistic understanding of aging. The other choices focus specifically on nursing (B), aging (C), or higher education (D), and do not encompass a wide range of disciplines like choice A. This makes them more specialized and less likely to have a diverse membership across different fields.

Correct Answer: A

Rationale: The correct answer is A because clients with hearing loss typically have difficulty hearing high-pitched tones, making it easier for them to respond to low-pitched tones. Low-pitched tones are easier for individuals with hearing loss to perceive due to the nature of hearing loss affecting the ability to hear higher frequencies. Choice B is incorrect as it is a generalization that does not consider the specific nature of hearing loss. Choice C is incorrect because individuals with hearing loss may require various forms of assistance beyond just lip-reading. Choice D is incorrect as individuals with hearing loss generally struggle more with high-pitched tones.

Correct Answer: C

Rationale: The correct answer is C: "It is the brain's ability to maintain function despite age-related changes and pathology." Cognitive reserve in older adults refers to the brain's ability to withstand age-related changes and pathology while maintaining cognitive function. This concept suggests that individuals with higher cognitive reserve may show fewer cognitive deficits even in the presence of brain damage or pathology. Choice A is incorrect because cognitive reserve is not about compensating for damage through enhanced neurogenesis but rather about maintaining function despite changes. Choice B is incorrect because cognitive reserve is not specifically about the relationship between cognitive decline and physical health; it focuses on maintaining cognitive function. Choice D is incorrect because cognitive reserve is not about developing new cognitive abilities later in life but rather preserving existing cognitive function.
