Which physiological change in the brain is the reason the nurse allows more time for answering questions with older adults?

Correct Answer: D

Rationale: The correct answer is D: Atrophy of dendrites in the cerebral cortex. With aging, there is a natural decline in brain volume and synaptic connections, leading to reduced dendritic branching and synaptic density in the cerebral cortex. This affects processing speed and cognitive functions, requiring more time for older adults to respond to questions. Rationale: A: Increased secretion of cholinesterase is not a physiological change associated with aging that would require more time for answering questions. B: Decreased secretion of neurotransmitters may occur with aging but is not the primary reason for slower processing speed in older adults. C: Loss of spinal cord and brainstem neurons is not the main factor influencing older adults' response time to questions compared to atrophy of dendrites in the cerebral cortex.

Correct Answer: B

Rationale: The correct answer is B because tuberculosis is an infectious bacterial disease that primarily affects the lungs. Clients taking immunosuppressant medications have weakened immune systems, making them more susceptible to developing active tuberculosis. This is due to the fact that the immune system is less able to fight off the bacteria causing tuberculosis. Choices A, C, and D are incorrect because tuberculosis is not spread by persons with positive skin tests and no symptoms, it is caused by bacteria (Mycobacterium tuberculosis) not a virus related to HIV, and it typically causes weight loss and not weight gain in the early stages.

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.

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.

Correct Answer: C

Rationale: The correct answer is C because regular repositioning and the use of pressure-relieving devices are essential to prevent skin breakdown in immobile older adults. Repositioning helps redistribute pressure, maintaining blood flow to the skin and preventing tissue damage. Pressure-relieving devices such as cushions or special mattresses further reduce pressure on vulnerable areas. Choices A and B do not address the root cause of skin breakdown and may even exacerbate the issue. Choice D is incorrect as complete bed rest can lead to further complications like pressure ulcers. In summary, choice C is the most effective intervention as it directly targets the risk factors for skin breakdown in immobile older adults.

Correct Answer: D

Rationale: The correct answer is D because nursing interventions can focus on enhancing the client's quality of life, comfort, and emotional well-being even in the face of terminal illness. Nurses can provide support, educate the client and family, manage symptoms, and empower the client to find meaning and purpose in their life. This approach contributes to a higher level of wellness by addressing holistic needs beyond just medical interventions. Incorrect choices: A: Wellness can be achieved through various means, not just aggressive medical interventions. B: Wellness is still achievable in terms of emotional, social, and spiritual well-being even with a terminal illness. C: Wellness involves physical, emotional, social, and spiritual aspects beyond just the absence of disease.

Correct Answer: C

Rationale: Rationale: C is correct as it involves understanding the patient's beliefs and preferences, crucial in culturally competent care. A would not address the patient's perspective directly. B is broad and lacks specificity. D assumes all traditional Chinese individuals seek Chinese medicine, which may not be the case.

Correct Answer: A

Rationale: The correct answer is A: Free radical theory. Vitamin C is thought to prevent aging by combatting free radicals, which are highly reactive molecules that can damage cells and contribute to aging. Vitamin C acts as an antioxidant, neutralizing free radicals and protecting cells from oxidative damage. Immunological theory (B) focuses on the role of the immune system in aging. Oxidative stress theory (C) is related to free radical theory but does not specifically address the role of vitamin C. Telomere theory (D) pertains to the shortening of telomeres, which are protective structures at the end of chromosomes, but is not directly related to the role of vitamin C in preventing aging.

Correct Answer: A

Rationale: The correct answer is A: Gerontological nursing certification indicates that a nurse has advanced knowledge and skills specifically related to the care of older adults. This is accurate because gerontological nursing certification is a voluntary certification that demonstrates a nurse's specialized expertise in caring for the elderly population. Nurses who obtain this certification have undergone additional training and education in gerontological nursing, making them more competent in addressing the unique needs of older adults. Choices B, C, and D are incorrect: B: All nurses in long-term care must obtain gerontological certification after completing their initial training - This is false as gerontological certification is not mandatory for all nurses in long-term care. C: Certification in gerontology is only necessary for nurses working in rehabilitation centers - This is incorrect as gerontological certification is beneficial for nurses caring for older adults in various settings, not just rehabilitation centers. D: Only nurses with a master's degree can achieve certification in gerontology - This is not true as nurses with
