Which of the following interventions has been shown to delay the onset of dementia in older adults?
- A. Strict dietary restrictions
- B. Consistent mental and physical activity
- C. Regular social isolation for mental clarity
- D. Pharmacologic interventions to control hypertension
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.

Which common cognitive impairment is often mistaken for normal aging in older adults?
- A. Mild cognitive impairment (MCI)
- B. Alzheimer's disease
- C. Dementia with Lewy bodies
- D. Vascular dementia
Correct Answer: A
Rationale: The correct answer is A: Mild cognitive impairment (MCI). MCI is often mistaken for normal aging because it involves subtle changes in memory and thinking abilities that are beyond what is expected for age but not severe enough to be classified as dementia. Individuals with MCI may experience forgetfulness or difficulty with complex tasks, which can be misconstrued as typical age-related changes. Alzheimer's disease (B), dementia with Lewy bodies (C), and vascular dementia (D) are all forms of dementia characterized by more significant cognitive decline and functional impairment compared to MCI, making them less likely to be confused with normal aging.
The term health disparity is defined as
- A. The systematic elimination of the culture of another resulting in decreased wellness.
- B. Differences in health outcomes among groups.
- C. The difference between an expected incidence and prevalence and that which actually occurs in a comparison population group.
- D. The existence of more than one group with differing values and perspective.
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.
Which physiological change in the brain is the reason the nurse allows more time for answering questions with older adults?
- A. Increased secretion of cholinesterase
- B. Decreased secretion of neurotransmitters
- C. Loss of spinal cord and brainstem neurons
- D. Atrophy of dendrites in the cerebral cortex
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.
In which context are members of a cohort described when using the age-stratification theory to explain the effect of similar events, conditions, and circumstances?
- A. Historical
- B. Biological
- C. Sociological
- D. Chronological
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.
A man is terminally ill with end-stage prostate cancer. Which is the best statement about this man’s wellness?
- A. Wellness can only be achieved with aggressive medical interventions.
- B. Wellness is not a real option for this client because he is terminally ill.
- C. Wellness is defined as the absence of disease.
- D. Nursing interventions can help empower a client to achieve a higher level of wellness.
Correct Answer: D
Rationale: The correct answer is D because nursing interventions can focus on enhancing the client's quality of life, comfort, and emotional well-being even in the face of terminal illness. Nurses can provide support, educate the client and family, manage symptoms, and empower the client to find meaning and purpose in their life. This approach contributes to a higher level of wellness by addressing holistic needs beyond just medical interventions.
Incorrect choices:
A: Wellness can be achieved through various means, not just aggressive medical interventions.
B: Wellness is still achievable in terms of emotional, social, and spiritual well-being even with a terminal illness.
C: Wellness involves physical, emotional, social, and spiritual aspects beyond just the absence of disease.
