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.

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.
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.
A case manager is likely to have how many years of nursing education?
- A. 1 to 1.5
- B. 4 to 6
- C. 2
- D. 8 or more
Correct Answer: C
Rationale: The correct answer is C: 2 years. A case manager typically requires a minimum of 2 years of nursing education to effectively coordinate care for patients. This level of education provides the necessary knowledge and skills to assess, plan, implement, and evaluate patient care.
- A: 1 to 1.5 years - Insufficient to acquire the depth of knowledge needed for case management.
- B: 4 to 6 years - Excessive for the role of a case manager, as it typically does not require a bachelor's degree.
- D: 8 or more years - Overqualified for the position of a case manager, as this level of education is beyond what is necessary for the role.
A community health nurse provides a flu prevention workshop at a senior center. Which theory of aging underpins these activities?
- A. Free radical theory
- B. Immunologic theory
- C. Oxidative stress theory
- D. Telomere theory
Correct Answer: B
Rationale: The correct answer is B: Immunologic theory. This theory of aging focuses on the decline in immune function as individuals age, making them more vulnerable to infections like the flu. The flu prevention workshop at the senior center aligns with this theory by aiming to boost seniors' immune systems to reduce their susceptibility to the flu.
A: Free radical theory attributes aging to the accumulation of damage caused by reactive oxygen species, not specifically related to immune function.
C: Oxidative stress theory is similar to the free radical theory in emphasizing the role of oxidative damage in aging, not directly related to immune function.
D: Telomere theory suggests that cellular aging is influenced by the shortening of telomeres, which is not directly related to immune function or flu prevention.
What is the most significant predictor of social isolation in older adults?
- A. Lack of access to healthcare
- B. Limited income and resources
- C. Loss of a spouse or close family member
- D. High levels of physical activity
Correct Answer: C
Rationale: The correct answer is C: Loss of a spouse or close family member. This is the most significant predictor of social isolation in older adults because losing a spouse or close family member can result in decreased social interactions and emotional support. This loss can lead to feelings of loneliness and isolation.
Incorrect options:
A: Lack of access to healthcare - While lack of access to healthcare can impact overall health, it is not the primary factor contributing to social isolation.
B: Limited income and resources - Financial constraints can affect social activities, but they are not as impactful as losing a loved one.
D: High levels of physical activity - While physical activity is important for overall well-being, it is not directly correlated with social isolation in older adults.
