Question 1 of 9

Which of the following is a key sign of dehydration in older adults that differs from younger populations?

Correct Answer: D

Rationale: The correct answer is D: Confusion or cognitive decline. In older adults, dehydration can manifest differently than in younger populations. Cognitive decline is a key sign of dehydration in older adults due to the brain being more sensitive to fluid loss. Dehydration can lead to confusion, disorientation, and impaired cognitive function in older individuals. Dark-colored urine (A) is a common sign of dehydration in all age groups. Increased thirst (B) is a general sign of dehydration but may not be as prominent in older adults due to decreased thirst sensation. Dry mouth and skin (C) are also common signs of dehydration but may not be as reliable indicators in older adults compared to cognitive changes.

Question 2 of 9

Which of the following can significantly improve the quality of life for older adults with chronic pain?

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.

Question 3 of 9

An older women tells the nurse that her husband seldom brushes his teeth as he did in the past. A reason why older clients stop participating in daily oral hygiene, such as brushing the teeth, include:

Correct Answer: A

Rationale: The correct answer is A: Decreased manual dexterity and inability to hold a toothbrush. As people age, they may experience decreased hand strength and motor skills, making it difficult to hold and manipulate objects like a toothbrush. This can lead to a decline in oral hygiene practices. Malocclusion of teeth (B) does not directly impact the ability to brush teeth. Decrease in taste acuity (C) may affect appetite but not tooth brushing habits. Lack of dental insurance (D) is a financial barrier and may affect access to dental care, but it does not directly impact the physical ability to brush teeth.

Question 4 of 9

Which common cognitive impairment is often mistaken for normal aging in older adults?

Correct Answer: A

Rationale: The correct answer is A: Mild cognitive impairment (MCI). MCI is often mistaken for normal aging because it involves subtle changes in memory and thinking abilities that are beyond what is expected for age but not severe enough to be classified as dementia. Individuals with MCI may experience forgetfulness or difficulty with complex tasks, which can be misconstrued as typical age-related changes. Alzheimer's disease (B), dementia with Lewy bodies (C), and vascular dementia (D) are all forms of dementia characterized by more significant cognitive decline and functional impairment compared to MCI, making them less likely to be confused with normal aging.

Question 5 of 9

An older adult who is a traditional Chinese man has a blood pressure of 80/54 mm Hg and refuses to remain in the bed. Which intervention should the nurse use to promote and maintain his health?

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.

Question 6 of 9

What is the primary role of the gerontological nurse when providing end-of-life care for a terminally ill older adult?

Correct Answer: B

Rationale: The correct answer, B, is the primary role of the gerontological nurse when providing end-of-life care for a terminally ill older adult. This choice emphasizes the importance of pain management, comfort care, and preserving the patient's dignity. The nurse's focus should be on enhancing the quality of life and ensuring the patient's comfort rather than pursuing aggressive curative treatments (A). Administering sedatives (C) should be based on individual needs and preferences, not as a blanket approach. While family involvement is crucial, the nurse should still advocate for the patient's autonomy and preferences, rather than solely relying on family decisions (D).

Question 7 of 9

A family member asks if vitamin C will prevent aging. The nurse considers which theory?

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.

Question 8 of 9

The home care nurse is performing an environmental assessment in the home of an older adult. Which of the following requires immediate nursing action?

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.

Question 9 of 9

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.
