Decreased functioning of which physical structure is likely to result in decreased metabolism in older adults?
- A. Kidney
- B. Thyroid gland
- C. Brain
- D. Skeleton
Correct Answer: B
Rationale: The correct answer is B: Thyroid gland. The thyroid gland produces hormones that regulate metabolism. In older adults, decreased thyroid function, known as hypothyroidism, can lead to a decrease in metabolism. This can result in symptoms such as fatigue, weight gain, and slowed heart rate.
A: Kidney - While the kidneys play a role in filtering waste and maintaining fluid balance, decreased kidney function typically does not directly impact metabolism.
C: Brain - The brain plays a crucial role in regulating various bodily functions, but it does not directly control metabolism.
D: Skeleton - The skeleton provides structural support and protects organs but does not directly influence metabolism.

Which type of exercise is most beneficial for older adults to prevent falls and maintain balance?
- A. Swimming
- B. Weight training
- C. Yoga and tai chi
- D. Running
Correct Answer: C
Rationale: The correct answer is C: Yoga and tai chi. These exercises focus on balance, flexibility, and strength, which are crucial for preventing falls in older adults. Yoga and tai chi also promote mindfulness and body awareness, further enhancing balance and coordination. Swimming (choice A) is beneficial for overall fitness but may not specifically target balance and fall prevention. Weight training (choice B) is important for muscle strength but may not address balance and flexibility adequately. Running (choice D) is high-impact and may actually increase the risk of falls for older adults.
Which of the following best describes the concept of "cognitive reserve" in older adults?
- A. It refers to the brain's ability to compensate for damage through enhanced neurogenesis.
- B. It refers to the relationship between cognitive decline and physical health.
- C. It is the brain's ability to maintain function despite age-related changes and pathology.
- D. It is the process of developing new cognitive abilities later in life.
Correct Answer: C
Rationale: The correct answer is C: "It is the brain's ability to maintain function despite age-related changes and pathology." Cognitive reserve in older adults refers to the brain's ability to withstand age-related changes and pathology while maintaining cognitive function. This concept suggests that individuals with higher cognitive reserve may show fewer cognitive deficits even in the presence of brain damage or pathology.
Choice A is incorrect because cognitive reserve is not about compensating for damage through enhanced neurogenesis but rather about maintaining function despite changes.
Choice B is incorrect because cognitive reserve is not specifically about the relationship between cognitive decline and physical health; it focuses on maintaining cognitive function.
Choice D is incorrect because cognitive reserve is not about developing new cognitive abilities later in life but rather preserving existing cognitive function.
Which action should the nurse take when addressing older adults?
- A. Speak in an exaggerated pitch.
- B. Use a lower quality of speech.
- C. Use endearing terms such as 'honey.'
- D. Speak clearly.
Correct Answer: D
Rationale: The correct answer is D: Speak clearly. This is important when addressing older adults as many may have hearing impairments. Speaking clearly helps ensure they can understand and follow instructions. Using an exaggerated pitch (A) may come across as patronizing. Using a lower quality of speech (B) can be perceived as disrespectful. Using endearing terms (C) may not be appropriate for all individuals and can be seen as condescending. In summary, speaking clearly is the most effective way to communicate respectfully with older adults.
What is the primary goal of the Program for All-Inclusive Care for the Elderly (PACE)?
- A. To provide intensive medical treatment for seniors
- B. To ensure nursing home placement for frail seniors
- C. To offer holistic care that allows older adults to live in the community
- D. To reduce healthcare costs for elderly populations
Correct Answer: C
Rationale: The correct answer is C: To offer holistic care that allows older adults to live in the community. PACE aims to provide comprehensive and coordinated care to help seniors remain independent in their homes and communities. This includes medical, social, and behavioral services. Choice A is incorrect as PACE focuses on holistic care rather than just intensive medical treatment. Choice B is incorrect as PACE aims to prevent nursing home placement by supporting older adults to live at home. Choice D is incorrect as while PACE may help reduce healthcare costs through preventive and coordinated care, the primary goal is to support seniors in living in the community.
Which condition is often misdiagnosed as depression in older adults?
- A. Chronic fatigue syndrome
- B. Dementia
- C. Anemia
- D. Sleep apnea
Correct Answer: B
Rationale: The correct answer is B: Dementia. Older adults often experience cognitive decline, memory loss, and behavioral changes that can be mistaken for symptoms of depression. Dementia is a common condition in the elderly that can be misdiagnosed due to overlapping symptoms such as apathy, social withdrawal, and changes in sleep patterns. Chronic fatigue syndrome (A), anemia (C), and sleep apnea (D) may also present with symptoms of fatigue and sleep disturbances, but they are less likely to be confused with depression in older adults compared to dementia.
