Which factor is most closely associated with cognitive decline in older adults?
- A. Genetic predisposition to neurodegenerative diseases
- B. Limited physical activity and poor nutrition
- C. Social engagement and mental stimulation
- D. Early retirement and lack of work-related stress
Correct Answer: B
Rationale: The correct answer is B because limited physical activity and poor nutrition have been consistently linked to cognitive decline in older adults. Physical activity promotes blood flow to the brain, which helps with cognitive function. Additionally, a balanced diet rich in nutrients supports brain health. Genetic predisposition (A) can play a role but is not the most closely associated factor. Social engagement and mental stimulation (C) are beneficial for cognitive health but not the primary factor for decline. Early retirement and lack of work-related stress (D) are not directly linked to cognitive decline.

On which biological theory of aging is the prevention of telomere shortening based?
- A. Genetic research
- B. Caloric restriction
- C. Oxidative stress
- D. Cross-link
Correct Answer: A
Rationale: The correct answer is A: Genetic research. Telomere shortening is primarily based on the theory of cellular senescence, which is related to genetic research. Telomeres are protective caps at the end of chromosomes that shorten with each cell division. Genetic research has shown that telomere shortening is associated with aging and age-related diseases. Caloric restriction, oxidative stress, and cross-link theories of aging are not directly linked to telomere shortening. Caloric restriction focuses on extending lifespan by reducing calorie intake, oxidative stress theory suggests that aging is caused by cumulative damage from reactive oxygen species, and cross-link theory emphasizes the accumulation of non-reversible bonds between molecules as a cause of aging.
The nurse is teaching an older client about measures to prevent constipation. What statement made by the client indicates further teaching is needed?
- A. "I'll walk 1-2 miles everyday"
- B. "I need to decrease fiber in my diet"
- C. "I have a bowel movement everyday"
- D. "I drink 6-8 glasses of water everyday"
Correct Answer: B
Rationale: The correct answer is B because decreasing fiber in the diet can actually worsen constipation. Fiber helps promote regular bowel movements by adding bulk to the stool. Walking and staying hydrated (choices A and D) are effective strategies to prevent constipation. Having a daily bowel movement (choice C) is a positive sign of bowel health. By choosing to decrease fiber intake, the client may inadvertently reduce the effectiveness of their bowel movements, leading to constipation.
Which organization had the largest influence in the specialty of gerontological nursing?
- A. American Association of Retired Persons (AARP)
- B. John Hartford Foundation
- C. Medicare
- D. Mutual of Omaha Insurance
Correct Answer: B
Rationale: The correct answer is B: John Hartford Foundation. The John Hartford Foundation is known for its significant contributions to the field of gerontological nursing through funding research, education, and initiatives to improve care for older adults. The foundation has supported the development of gerontological nursing programs and resources, making it a key influencer in advancing the specialty.
Explanation for other choices:
A: American Association of Retired Persons (AARP) primarily focuses on advocacy and support for older adults but does not have a direct influence on the specialty of gerontological nursing.
C: Medicare is a federal health insurance program for individuals aged 65 and older, but it does not specifically impact the development of gerontological nursing as an organization.
D: Mutual of Omaha Insurance is an insurance company and does not have a direct role in shaping the field of gerontological nursing.
How does loneliness affect older adults' health?
- A. It has no significant impact on health
- B. It can increase the risk of cardiovascular disease and depression
- C. It improves immune function
- D. It only affects mental health, not physical health
Correct Answer: B
Rationale: Loneliness in older adults can lead to increased stress, inflammation, and unhealthy behaviors, all of which can elevate the risk of cardiovascular disease and depression. Social isolation can also impact mental health. Choice A is incorrect as loneliness does impact health. Choice C is incorrect as loneliness typically weakens immune function. Choice D is incorrect as loneliness affects both mental and physical health.
All of the following are characteristics associated with centenarians EXCEPT:
- A. Exercise.
- B. Smoking.
- C. Weight control.
- D. Delayed onset of disease.
Correct Answer: B
Rationale: The correct answer is B: Smoking. Centenarians are individuals who live to be 100 years old or older and smoking is a known risk factor for various diseases and premature death. Exercise, weight control, and delayed onset of disease are commonly associated characteristics of centenarians as they promote overall health and longevity. Smoking, on the other hand, has been proven to have detrimental effects on health and is not typically seen in individuals who live to be 100 or older. Therefore, the absence of smoking is a more accurate characteristic associated with centenarians.
