Decreased functioning of which physical structure is likely to result in decreased metabolism in older adults?

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.

Correct Answer: A

Rationale: The correct answer is A because most areas of the brain do not lose brain cells with age due to a process called neuroplasticity. This means that the brain can adapt and reorganize itself by forming new connections between existing brain cells. Memory decline is not inevitable (B) as cognitive decline varies among individuals and can be influenced by factors like lifestyle and genetics. Basic intelligence can change with age (C) due to various factors such as experience and education. The brain does continue to make new brain cells through a process called neurogenesis, making choice D incorrect.

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.

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.

Correct Answer: D

Rationale: The correct answer is D because memory loss affecting daily functioning is a key indicator of dementia, not normal aging. Normal aging may involve some forgetfulness, but it typically does not significantly impact daily activities. Choice A is incorrect because difficulty recalling recent events can occur in both normal aging and dementia. Choice B is incorrect as increased forgetfulness is a common feature of aging and may not necessarily indicate dementia. Choice C is incorrect as forgetting names of familiar people can also be a normal part of aging and does not solely point to dementia. Memory loss affecting daily functioning is a more specific and severe symptom that strongly suggests dementia over normal aging.

Correct Answer: A

Rationale: The correct answer is A because losing one's teeth is not a normal part of the aging process. Teeth loss is primarily due to poor oral hygiene, dental diseases, and other factors, not solely aging. Step 1: Aging itself does not directly cause tooth loss. Step 2: Proper oral care and regular dental checkups can prevent tooth loss. Step 3: Edentulous clients still need dental checkups for oral health. Step 4: Regular dental exams can prevent tooth loss and improve chewing ability. Step 5: The incidence of oral malignancies does increase with age, emphasizing the importance of regular oral exams. Incorrect answers: B: Clients who are edentulous need dental checkups for oral health. C: Regular exams can prevent tooth loss and improve chewing ability. D: Oral malignancies increase with age, highlighting the importance of regular oral exams. Overall, maintaining good oral hygiene and regular dental visits are crucial for elderly individuals' oral health, preventing tooth

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.

Correct Answer: B

Rationale: The correct answer is B: Family support and involvement. This is crucial in determining the effectiveness of rehabilitation after a stroke because a supportive and involved family can provide emotional support, encouragement, and assistance with activities of daily living. This positively impacts the patient's motivation, compliance with treatment, and overall well-being, leading to better rehabilitation outcomes. A: Age of the patient - While age can be a factor in stroke recovery, it is not the most important factor as older patients can still make significant progress with proper rehabilitation and support. C: Number of medications prescribed - While medication management is important in stroke recovery, it is not the most crucial factor for rehabilitation effectiveness. D: Patient’s previous health conditions - While previous health conditions can impact stroke recovery, the level of family support and involvement plays a more significant role in determining the effectiveness of rehabilitation after a stroke.

Correct Answer: A

Rationale: Step-by-step rationale: 1. Aging causes decreased collagen production, leading to decreased skin elasticity and thinning. 2. Loss of subcutaneous fat contributes to the appearance of aging skin. 3. Wrinkles and sagging are common signs of decreased skin elasticity in older adults. 4. Increased muscle mass, increased cardiac output, and increased renal filtration rate are not typical age-related changes. Summary: Skin changes such as decreased elasticity and thinning are common in older adults due to reduced collagen production and loss of subcutaneous fat. Increased muscle mass, cardiac output, and renal filtration rate are not typical age-related changes.
