The term health disparity is defined as

Correct Answer: B

Rationale: The correct answer is B because health disparity refers to variations in health outcomes among different groups due to factors such as socioeconomic status, race, ethnicity, etc. This definition accurately captures the essence of health disparity as it highlights the unequal distribution of health outcomes. Choice A is incorrect because it refers to cultural elimination, which is not the definition of health disparity. Choice C is incorrect as it talks about differences in expected and actual incidence, not health outcomes among groups. Choice D is incorrect as it focuses on values and perspectives rather than health outcomes.

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: Unsecured scattered rugs. This requires immediate nursing action as it poses a significant fall risk for the older adult. Rugs can cause tripping hazards, leading to potential injuries. The nurse should secure or remove the rugs to ensure the safety of the patient. Summary of other choices: B: Operable smoke detector - While important for safety, it does not require immediate nursing action as it is already in working condition. C: Prefilled medication cassette - This is not an immediate safety concern and can be addressed during routine medication management. D: Unsecured scattered rugs (repeated) - This choice is the same as the correct answer, so it is incorrect.

Correct Answer: C

Rationale: The correct answer is C - Difficulty walking and balance issues. Frailty in older adults is characterized by physical weakness, decreased muscle strength, and reduced functional capacity. Difficulty walking and balance issues are key indicators of frailty as they reflect a decline in physical capabilities. Increased muscle mass (A) is not a sign of frailty but rather a positive indicator of strength. Unexplained weight gain (B) may not necessarily be related to frailty. Improved cognitive function (D) is unrelated to physical frailty.

Correct Answer: C, D, E

Rationale: The correct answers are C, D, and E. C is crucial as it allows for effective communication, D involves observing nonverbal cues, and E emphasizes the need for clear and concise language. A is incorrect as the nurse should address the client directly, not just the interpreter. B is incorrect as using technical terms may hinder understanding.

Correct Answer: B

Rationale: The correct answer, B, is the primary role of the gerontological nurse when providing end-of-life care for a terminally ill older adult. This choice emphasizes the importance of pain management, comfort care, and preserving the patient's dignity. The nurse's focus should be on enhancing the quality of life and ensuring the patient's comfort rather than pursuing aggressive curative treatments (A). Administering sedatives (C) should be based on individual needs and preferences, not as a blanket approach. While family involvement is crucial, the nurse should still advocate for the patient's autonomy and preferences, rather than solely relying on family decisions (D).

Correct Answer: D

Rationale: The correct answer is D: Confusion or cognitive decline. In older adults, dehydration can manifest differently than in younger populations. Cognitive decline is a key sign of dehydration in older adults due to the brain being more sensitive to fluid loss. Dehydration can lead to confusion, disorientation, and impaired cognitive function in older individuals. Dark-colored urine (A) is a common sign of dehydration in all age groups. Increased thirst (B) is a general sign of dehydration but may not be as prominent in older adults due to decreased thirst sensation. Dry mouth and skin (C) are also common signs of dehydration but may not be as reliable indicators in older adults compared to cognitive changes.

Correct Answer: C

Rationale: The correct answer is C: Social engagement and support. Social engagement has been identified as a crucial factor in successful aging, as it contributes to emotional well-being, cognitive function, and overall quality of life. Older adults with strong social networks tend to have better physical and mental health outcomes. Social support can help individuals cope with stress, reduce feelings of loneliness and isolation, and provide a sense of purpose and belonging. Financial security (A) is important but not the most significant predictor. Physical fitness and health (B) are essential but do not solely determine successful aging. Mental resilience (D) is valuable, but the social aspect plays a more significant role in aging successfully.

Correct Answer: C

Rationale: The correct answer is C because regular repositioning and the use of pressure-relieving devices are essential to prevent skin breakdown in immobile older adults. Repositioning helps redistribute pressure, maintaining blood flow to the skin and preventing tissue damage. Pressure-relieving devices such as cushions or special mattresses further reduce pressure on vulnerable areas. Choices A and B do not address the root cause of skin breakdown and may even exacerbate the issue. Choice D is incorrect as complete bed rest can lead to further complications like pressure ulcers. In summary, choice C is the most effective intervention as it directly targets the risk factors for skin breakdown in immobile older adults.
