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.

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.
An older adult who is a traditional Chinese man has a blood pressure of 80/54 mm Hg and refuses to remain in the bed. Which intervention should the nurse use to promote and maintain his health?
- A. Have the health care provider speak to him.
- B. Use principles of the holistic health system.
- C. Ask about his perceptions and treatment ideas.
- D. Consult with a practitioner of Chinese medicine.
Correct Answer: C
Rationale: Rationale:
C is correct as it involves understanding the patient's beliefs and preferences, crucial in culturally competent care. A would not address the patient's perspective directly. B is broad and lacks specificity. D assumes all traditional Chinese individuals seek Chinese medicine, which may not be the case.
Which of the following is the leading cause of hospitalization for older adults in the United States?
- A. Pneumonia
- B. Stroke
- C. Diabetes
- D. Congestive heart failure
Correct Answer: A
Rationale: The correct answer is A: Pneumonia. Older adults are more susceptible to pneumonia due to weakened immune systems and other health conditions. Pneumonia can lead to severe complications requiring hospitalization. Stroke (B) affects a significant number of older adults but is not the leading cause of hospitalization. Diabetes (C) and Congestive heart failure (D) are prevalent in older adults but are not the primary reason for hospitalization. Pneumonia's severity and impact on older adults' health make it the leading cause of hospitalization.
A retirement community is divided into different communities with different activities available for the residents. There is one community for individuals ages 65 to 74 years, one for individuals ages 75 to 85 years, and one for individuals older than age 85 years. This is consistent with which theory of aging?
- A. Role theory
- B. Disengagement theory
- C. Age-stratification theory
- D. Social exchange theory
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.
A nurse is caring for a culturally diverse patient who has missed follow-up appointments. The patient says: “You don’t understand—in my culture, we don’t do things like that.” The nurse understands which of the following about the patient’s culture?
- A. The culture does not value Western medicine.
- B. The culture has a different orientation to time than Western medicine.
- C. The culture is an interdependent culture.
- D. The culture does not believe in preventative care.
Correct Answer: B
Rationale: The correct answer is B: The culture has a different orientation to time than Western medicine. This is because the patient's statement about not following up on appointments due to cultural reasons suggests a difference in the perception and importance of time. In some cultures, time is more fluid and flexible compared to the rigid scheduling of Western medicine. This understanding helps the nurse provide culturally sensitive care.
Choices A, C, and D are incorrect:
A: The culture does not value Western medicine - This is not necessarily implied by the patient's statement about cultural differences.
C: The culture is an interdependent culture - The patient's statement does not provide direct evidence of the culture being interdependent.
D: The culture does not believe in preventative care - There is no indication in the patient's statement that the culture does not believe in preventative care.
