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: 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

Correct Answer: A

Rationale: The correct answer is A: Unsecured scattered rugs. This requires immediate nursing action as it poses a significant fall risk for the older adult. Rugs can cause tripping hazards, leading to potential injuries. The nurse should secure or remove the rugs to ensure the safety of the patient. Summary of other choices: B: Operable smoke detector - While important for safety, it does not require immediate nursing action as it is already in working condition. C: Prefilled medication cassette - This is not an immediate safety concern and can be addressed during routine medication management. D: Unsecured scattered rugs (repeated) - This choice is the same as the correct answer, so it is incorrect.

Correct Answer: C

Rationale: The correct answer is C: Social engagement and support. Social engagement has been identified as a crucial factor in successful aging, as it contributes to emotional well-being, cognitive function, and overall quality of life. Older adults with strong social networks tend to have better physical and mental health outcomes. Social support can help individuals cope with stress, reduce feelings of loneliness and isolation, and provide a sense of purpose and belonging. Financial security (A) is important but not the most significant predictor. Physical fitness and health (B) are essential but do not solely determine successful aging. Mental resilience (D) is valuable, but the social aspect plays a more significant role in aging successfully.

Correct Answer: A

Rationale: The correct answer is A: Diarrhea. Diarrhea is not a risk factor for developing pneumonia in elderly individuals. The rationale for this is that pneumonia is primarily caused by respiratory infections, not gastrointestinal issues like diarrhea. Neurological disease, heart failure, and COPD are all risk factors for pneumonia because they can weaken the immune system or impair lung function, making individuals more susceptible to respiratory infections. These conditions can lead to aspiration, impaired cough reflex, or compromised lung function, increasing the likelihood of developing pneumonia.

Correct Answer: B

Rationale: The correct answer is B: The culture has a different orientation to time than Western medicine. This is because the patient's statement about not following up on appointments due to cultural reasons suggests a difference in the perception and importance of time. In some cultures, time is more fluid and flexible compared to the rigid scheduling of Western medicine. This understanding helps the nurse provide culturally sensitive care. Choices A, C, and D are incorrect: A: The culture does not value Western medicine - This is not necessarily implied by the patient's statement about cultural differences. C: The culture is an interdependent culture - The patient's statement does not provide direct evidence of the culture being interdependent. D: The culture does not believe in preventative care - There is no indication in the patient's statement that the culture does not believe in preventative care.

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.

Correct Answer: B

Rationale: The correct answer is B: Benzodiazepines. Benzodiazepines are central nervous system depressants that can cause drowsiness, dizziness, and confusion, increasing the risk of falls in older adults. They can also impair balance and coordination. Older adults are more sensitive to these effects due to age-related changes in metabolism and increased risk of cognitive impairment. Beta-blockers (A), statins (C), and antihypertensives (D) are generally safe in older adults and do not directly increase the risk of falls. Beta-blockers can sometimes cause dizziness but are more commonly associated with bradycardia. Statins are used to lower cholesterol levels and do not affect fall risk. Antihypertensives help lower blood pressure and can actually reduce the risk of falls by preventing conditions like orthostatic hypotension.

Correct Answer: A

Rationale: The correct answer is A because neglecting personal grooming indicates a lack of self-care, which is a common sign of ineffective coping after the loss of a loved one. This behavior suggests the client may be struggling emotionally and unable to engage in basic self-care tasks. Looking at old pictures, participating in social activities, and visiting the husband's grave are all healthy coping mechanisms that can help the client process her grief and maintain connections with her late husband.
