A family member asks if vitamin C will prevent aging. The nurse considers which theory?

Correct Answer: A

Rationale: The correct answer is A: Free radical theory. Vitamin C is thought to prevent aging by combatting free radicals, which are highly reactive molecules that can damage cells and contribute to aging. Vitamin C acts as an antioxidant, neutralizing free radicals and protecting cells from oxidative damage. Immunological theory (B) focuses on the role of the immune system in aging. Oxidative stress theory (C) is related to free radical theory but does not specifically address the role of vitamin C. Telomere theory (D) pertains to the shortening of telomeres, which are protective structures at the end of chromosomes, but is not directly related to the role of vitamin C in preventing aging.

Correct Answer: A

Rationale: The correct answer is A: Historical. In age-stratification theory, cohort members are described in historical context to explain shared experiences. This theory emphasizes that individuals born around the same time experience similar events shaping their lives. Historical context is crucial as it considers the societal, cultural, and economic factors influencing a specific generation. Choice B, Biological, is incorrect as age-stratification theory focuses on social aspects rather than biological ones. Choice C, Sociological, is broad and doesn't specifically address the historical aspect of cohort description. Choice D, Chronological, is incorrect as it simply refers to the order of events without considering the historical backdrop of a cohort's experiences.

Correct Answer: D

Rationale: The correct answer is D: Atrophy of dendrites in the cerebral cortex. With aging, there is a natural decline in brain volume and synaptic connections, leading to reduced dendritic branching and synaptic density in the cerebral cortex. This affects processing speed and cognitive functions, requiring more time for older adults to respond to questions. Rationale: A: Increased secretion of cholinesterase is not a physiological change associated with aging that would require more time for answering questions. B: Decreased secretion of neurotransmitters may occur with aging but is not the primary reason for slower processing speed in older adults. C: Loss of spinal cord and brainstem neurons is not the main factor influencing older adults' response time to questions compared to atrophy of dendrites in the cerebral cortex.

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 because the TimeSlips program involves providing a picture as a creative prompt for group members to collaboratively create a story. This technique stimulates imagination and communication in cognitively impaired individuals. Choice B is incorrect as recording responses is not specific to the TimeSlips method. Choice C is incorrect as complimenting contributions is not a core component of the TimeSlips program. Choice D is incorrect as reading back the story during the session does not align with the collaborative, creative process of TimeSlips.
