Which of the following interventions has been shown to delay the onset of dementia in older adults?

Correct Answer: B

Rationale: The correct answer is B: Consistent mental and physical activity. Engaging in mental and physical activities can help improve cognitive function, increase brain plasticity, and reduce the risk of cognitive decline. Regular stimulation of the brain through activities like puzzles, reading, and learning new skills can help delay the onset of dementia. Physical activity also promotes overall brain health by improving circulation and reducing inflammation. Choices A, C, and D are incorrect: A: Strict dietary restrictions may have some benefits for overall health, but there is limited evidence to suggest that it directly delays the onset of dementia. C: Regular social isolation can actually increase the risk of cognitive decline and dementia, as social interaction is important for brain health. D: Pharmacologic interventions to control hypertension may be important for overall health, but they are not specifically shown to delay the onset of dementia in older adults.

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: 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 is B because demographic data shows an increasing aging population, leading to a higher demand for healthcare services for individuals over 85. This trend indicates a greater need for nursing services to cater to the specific health care needs of this age group. Option A is incorrect as the aging population will require more care. Option C is also incorrect as fewer nurses will not be sufficient to meet the increasing demand. Option D is irrelevant to the predictive trend of healthcare needs based on demographics.

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: B

Rationale: The correct answer is B: dehydration. Mr. J's symptoms of flu-like illness, diarrhea, vomiting, confusion, lethargy, dry skin, brown tongue, sunken cheeks, and concentrated urine are indicative of severe dehydration. Dehydration can lead to electrolyte imbalances, decreased blood volume, and impaired organ function, resulting in confusion and lethargy. Skin changes, dry mucous membranes, and concentrated urine are also classic signs of dehydration. The other choices (A, C, D) do not align with the constellation of symptoms presented by Mr. J and are less likely based on the information provided.

Correct Answer: B

Rationale: The correct answer is B because tuberculosis is an infectious bacterial disease that primarily affects the lungs. Clients taking immunosuppressant medications have weakened immune systems, making them more susceptible to developing active tuberculosis. This is due to the fact that the immune system is less able to fight off the bacteria causing tuberculosis. Choices A, C, and D are incorrect because tuberculosis is not spread by persons with positive skin tests and no symptoms, it is caused by bacteria (Mycobacterium tuberculosis) not a virus related to HIV, and it typically causes weight loss and not weight gain in the early stages.

Correct Answer: C

Rationale: The correct answer is C: Coordinating members of the health care team. This demonstrates leadership as the nurse is taking charge of organizing and communicating with various healthcare professionals to ensure the best care for the older patient. By collaborating with the wound care team, the nurse shows effective coordination and communication skills, which are crucial in managing complex cases in older adults. Assessing older adults effectively (choice A) is important but does not specifically address leadership in coordinating care. Facilitating access to eldercare programs (choice B) is important but does not directly demonstrate leadership in coordinating care. Empowering older adults to manage chronic illness (choice D) is important for patient education but does not directly show leadership in coordinating the healthcare team.

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.
