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.
What is a major risk factor for pressure ulcers in older adults?
- A. Lack of sleep
- B. Malnutrition and dehydration
- C. Excessive physical activity
- D. High blood pressure
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.
The nurse designs a group exercise program at a senior center. Which room should the nurse choose?
- A. Room with a hardwood floor and throw rugs
- B. Spacious room with no windows and a natural stone floor
- C. Room with a hardwood floor and large windows overlooking a garden area
- D. End room with linoleum floor and a fan for ventilation
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.
Which of the following interview questions would be most appropriate when a nurse is assessing a client's respiratory function?
- A. Would you be interested in finding out more about environmental smoke?
- B. Did either of your parents experience lung disease?
- C. Have you ever worked in a job where you were exposed to dust, fumes, smoke, or other pollutants?
- D. What do you do to actively maintain your health?
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.
Based on current demographic data, which of the following statements identifies a predictive trend regarding the health care needs of society?
- A. Most nurses will not need to care for older persons.
- B. More nursing services will be required to serve the needs of the population older than 85 years of age.
- C. Fewer nurses will be needed to care for older adults.
- D. Older adults expect their quality of life to be less than that of earlier generations at their ages.
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.
