Which of the following interventions has been shown to delay the onset of dementia in older adults?

Correct Answer: B

Rationale: The correct answer is B: Consistent mental and physical activity. Engaging in mental and physical activities can help improve cognitive function, increase brain plasticity, and reduce the risk of cognitive decline. Regular stimulation of the brain through activities like puzzles, reading, and learning new skills can help delay the onset of dementia. Physical activity also promotes overall brain health by improving circulation and reducing inflammation. Choices A, C, and D are incorrect: A: Strict dietary restrictions may have some benefits for overall health, but there is limited evidence to suggest that it directly delays the onset of dementia. C: Regular social isolation can actually increase the risk of cognitive decline and dementia, as social interaction is important for brain health. D: Pharmacologic interventions to control hypertension may be important for overall health, but they are not specifically shown to delay the onset of dementia in older adults.

Correct Answer: B

Rationale: The correct answer is B: high likelihood of orthostatic hypotension upon rising quickly. Orthostatic hypotension is a common issue in the elderly, causing a sudden drop in blood pressure when standing up quickly, leading to dizziness and falls. This factor directly contributes to the high incidence of falls in the elderly. Increased muscle mass and tone (A) actually reduce the risk of falls, while improving eyesight in dim light (C) would decrease the risk. Constipation (D) is not directly related to falls in the elderly.

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: A

Rationale: The correct answer is A: Pneumonia. Older adults are more susceptible to pneumonia due to weakened immune systems and other health conditions. Pneumonia can lead to severe complications requiring hospitalization. Stroke (B) affects a significant number of older adults but is not the leading cause of hospitalization. Diabetes (C) and Congestive heart failure (D) are prevalent in older adults but are not the primary reason for hospitalization. Pneumonia's severity and impact on older adults' health make it the leading cause of hospitalization.

Correct Answer: B

Rationale: The correct answer is B because the holistic health movement emphasizes treating the whole person - mind, body, and spirit. This shifts the focus from merely treating symptoms to considering individual well-being and lifestyle factors. Choice A is not the best answer because while disease prevention is part of holistic health, it is not the primary impact on health care. Choice C is incorrect as the movement does not directly improve access to health care. Choice D is also incorrect as while alternative modalities are part of holistic health, they are not the main impact on health care.

Correct Answer: C

Rationale: The correct answer is C: Cognitive-behavioral therapy (CBT) and physical therapy. CBT helps older adults manage pain through changing thought patterns and behaviors, improving coping skills. Physical therapy helps maintain mobility and reduce pain. Both approaches address the physical and psychological aspects of chronic pain, leading to better quality of life. Complete bed rest (A) can worsen pain and lead to muscle weakness. Unsupervised use of opioids (B) can be dangerous, leading to addiction and other health issues. Isolation and minimal social interaction (D) can contribute to depression and exacerbate pain.

Correct Answer: B

Rationale: The correct answer is B: dehydration. Mr. J's symptoms of flu-like illness, diarrhea, vomiting, confusion, lethargy, dry skin, brown tongue, sunken cheeks, and concentrated urine are indicative of severe dehydration. Dehydration can lead to electrolyte imbalances, decreased blood volume, and impaired organ function, resulting in confusion and lethargy. Skin changes, dry mucous membranes, and concentrated urine are also classic signs of dehydration. The other choices (A, C, D) do not align with the constellation of symptoms presented by Mr. J and are less likely based on the information provided.

Correct Answer: A

Rationale: The correct answer is A: Promoting wellness. Providing information about diet and exercise for a healthy diabetic client falls under promoting wellness because it focuses on proactive measures to maintain health and prevent complications. It aims to empower the client to make healthy lifestyle choices. B: Preventing illness is not the best description as the client is already diabetic, so the focus is on managing the condition rather than solely preventing it. C: Treating disease is not accurate because the client is already diabetic and the goal is not to treat the disease, but rather manage it effectively. D: Restoring health is not applicable in this scenario as the client is not in a state of compromised health that needs to be restored.

Correct Answer: B

Rationale: The correct answer is B because demographic data shows an increasing aging population, leading to a higher demand for healthcare services for individuals over 85. This trend indicates a greater need for nursing services to cater to the specific health care needs of this age group. Option A is incorrect as the aging population will require more care. Option C is also incorrect as fewer nurses will not be sufficient to meet the increasing demand. Option D is irrelevant to the predictive trend of healthcare needs based on demographics.
