What is the primary reason older adults with cognitive impairments experience difficulties with medication adherence?

Correct Answer: B

Rationale: The correct answer is B: Cognitive decline affecting memory and decision-making. Older adults with cognitive impairments, such as dementia, may struggle with remembering to take their medications as prescribed and making sound decisions regarding their medication regimen due to cognitive decline. Memory deficits can lead to missed doses, while impaired decision-making can result in improper adherence. Choices A, C, and D are incorrect as the primary reason for medication non-adherence in this population is the cognitive decline impacting memory and decision-making, rather than lack of understanding, physical inability, or fear of side effects.

Correct Answer: D

Rationale: The correct answer is D because sarcopenia, which is the age-related loss of muscle mass and strength, directly impacts balance and mobility in older adults. Muscle weakness from sarcopenia reduces stability and coordination, increasing the risk of falls. This affects functional independence as it limits the ability to perform daily activities safely. Choices A, B, and C are incorrect as sarcopenia primarily affects muscle mass and strength, not body fat, lung capacity, or joint stiffness.

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: B

Rationale: The correct answer is B: Statistically, neglect is the most common form of elder abuse. Neglect involves the failure to provide necessary care or assistance to an elderly person, making it a prevalent form of elder abuse. This is supported by research and studies on elder abuse cases. A is incorrect because elder abuse is often underreported compared to other forms of domestic violence. C is incorrect as many cases of elder abuse go unreported due to various reasons such as fear, shame, or lack of awareness. D is incorrect as healthcare practitioners are mandated to report any suspected cases of elder abuse, not just verified cases, to protect the well-being of the elderly.

Correct Answer: D

Rationale: The correct answer is D: cerebral vascular disease. Microvascular changes in diabetes mainly affect small blood vessels in organs like the eyes (retinopathy), kidneys (nephropathy), and nerves (neuropathy). Cerebral vascular disease involves larger blood vessels in the brain, not typically considered a result of microvascular changes in diabetes. Retinopathy, nephropathy, and neuropathy are well-documented complications of uncontrolled diabetes due to damage to small blood vessels in these specific organs.
