How does dehydration impact older adults more than younger adults?

Correct Answer: B

Rationale: The correct answer is B because older adults have reduced kidney function, which impairs their ability to concentrate urine and retain water. Additionally, they may have a diminished thirst sensation, making them less likely to drink enough fluids. This combination of factors makes older adults more vulnerable to dehydration compared to younger adults. Choice A is incorrect because older adults actually have a lower percentage of body water due to age-related changes in body composition. Choice C is incorrect as dehydration can indeed have a more significant impact on older adults due to their physiological changes. Choice D is incorrect as older adults are actually more prone to dehydration due to various age-related factors.

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: B

Rationale: The correct answer is B: Malnutrition and dehydration. Malnutrition and dehydration are major risk factors for pressure ulcers in older adults because they can lead to poor skin integrity, reduced tissue resilience, and impaired wound healing. Lack of sleep (choice A) may contribute to overall health issues but is not a direct risk factor for pressure ulcers. Excessive physical activity (choice C) can increase the risk of injury but does not directly cause pressure ulcers. High blood pressure (choice D) is a risk factor for cardiovascular issues but is not specifically linked to the development of pressure ulcers.

Correct Answer: C

Rationale: The most appropriate interview question for assessing a client's respiratory function is C: "Have you ever worked in a job where you were exposed to dust, fumes, smoke, or other pollutants?" This question directly relates to potential occupational exposures that could impact respiratory health. It helps gather specific information relevant to respiratory assessment. Choice A is unrelated to respiratory function assessment. Choice B focuses on familial history, which is important but not as direct as occupational exposure. Choice D is too general and does not specifically address respiratory issues. Therefore, C is the most appropriate choice for assessing respiratory function.

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 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: 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: C

Rationale: The correct answer is C because a room with hardwood floor and large windows overlooking a garden area offers a safe, non-slip surface for exercise and natural light for a pleasant environment. Hardwood floors are ideal for exercise to prevent slipping, and the large windows provide a view of the garden area, which can enhance motivation and mood. The other choices are incorrect because A has throw rugs, which can cause tripping hazards, B lacks natural light and ventilation, and D has a linoleum floor which may not be as safe for exercise compared to hardwood.

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.
