A community health nurse provides a flu prevention workshop at a senior center. Which theory of aging underpins these activities?

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.

Correct Answer: D

Rationale: The correct answer is D because pursed lip breathing helps prevent airway collapse by maintaining positive pressure in the airways, reduces anxiety by promoting relaxation, and enhances effective breathing by improving oxygen exchange. Choice A is incorrect as pursed lip breathing does not directly prevent the build-up of secretions. Choice B is incorrect as comfort is not the primary purpose of pursed lip breathing. Choice C is incorrect as while pursed lip breathing can improve respiratory muscle function, its primary benefit lies in preventing airway collapse, reducing anxiety, and promoting effective breathing.

Correct Answer: B

Rationale: The correct answer is B: Difficulty reading small print and decreased ability to focus on objects at varying distances. As people age, the lens of the eye becomes less flexible, leading to presbyopia, which results in difficulty seeing close objects clearly. This explains the client's decreased ability to accommodate. This choice is correct because presbyopia specifically affects near vision, making it harder to read small print and focus on objects up close. A: Blurring of vision due to increased intraocular pressure - This choice is incorrect because presbyopia is not related to increased intraocular pressure. C: Narrowing of field of vision-loss of peripheral vision - This choice is incorrect because presbyopia does not affect peripheral vision; it specifically impacts near vision. D: Sensitivity to light (photophobia) - This choice is incorrect because presbyopia does not cause sensitivity to light; it is solely related to difficulty in focusing on near objects.

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 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: 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: 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: A

Rationale: The correct answer is A because clients with hearing loss typically have difficulty hearing high-pitched tones, making it easier for them to respond to low-pitched tones. Low-pitched tones are easier for individuals with hearing loss to perceive due to the nature of hearing loss affecting the ability to hear higher frequencies. Choice B is incorrect as it is a generalization that does not consider the specific nature of hearing loss. Choice C is incorrect because individuals with hearing loss may require various forms of assistance beyond just lip-reading. Choice D is incorrect as individuals with hearing loss generally struggle more with high-pitched tones.

Correct Answer: B

Rationale: The correct answer is B because decreasing fiber in the diet can actually worsen constipation. Fiber helps promote regular bowel movements by adding bulk to the stool. Walking and staying hydrated (choices A and D) are effective strategies to prevent constipation. Having a daily bowel movement (choice C) is a positive sign of bowel health. By choosing to decrease fiber intake, the client may inadvertently reduce the effectiveness of their bowel movements, leading to constipation.
