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, 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).

Correct Answer: D

Rationale: The correct answer is D: Circulatory problems related to age and a chronic illness. Severe edema, hair loss on the legs, and foot ulcerations are indicative of poor circulation, often seen in conditions like peripheral artery disease. Age and chronic illnesses can contribute to circulatory issues. A diet low in protein (choice A) would not directly cause these symptoms. Exposure to cold (choice B) would not explain the specific symptoms mentioned. Frequent falls (choice C) do not align with the symptoms provided.

Correct Answer: C

Rationale: The correct answer is C because a room with hardwood floor and large windows overlooking a garden area offers a safe, non-slip surface for exercise and natural light for a pleasant environment. Hardwood floors are ideal for exercise to prevent slipping, and the large windows provide a view of the garden area, which can enhance motivation and mood. The other choices are incorrect because A has throw rugs, which can cause tripping hazards, B lacks natural light and ventilation, and D has a linoleum floor which may not be as safe for exercise compared to hardwood.

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: D

Rationale: The correct answer is D because assisting with upper endoscopy is not a standard nursing intervention for CHF. Nursing interventions for CHF focus on managing symptoms, medication adherence, and lifestyle modifications. Choices A, B, and C are correct as they address important aspects of CHF management such as monitoring symptoms, educating on medications, and promoting a low-sodium diet. Helping with an upper endoscopy is unrelated to the management of CHF and falls outside the scope of nursing care for this condition.

Correct Answer: C

Rationale: The most appropriate interview question for assessing a client's respiratory function is C: "Have you ever worked in a job where you were exposed to dust, fumes, smoke, or other pollutants?" This question directly relates to potential occupational exposures that could impact respiratory health. It helps gather specific information relevant to respiratory assessment. Choice A is unrelated to respiratory function assessment. Choice B focuses on familial history, which is important but not as direct as occupational exposure. Choice D is too general and does not specifically address respiratory issues. Therefore, C is the most appropriate choice for assessing respiratory function.

Correct Answer: C

Rationale: The correct answer is C: Age-stratification theory. This theory suggests that age is a powerful determinant of social organization. In the given scenario, the retirement community is structured based on age groups, indicating stratification by age. This separation aligns with the concept of age-based social hierarchies and differing opportunities and resources based on age. Choice A (Role theory) focuses on how individuals adapt to social roles as they age, which is not directly reflected in the scenario. Choice B (Disengagement theory) posits that aging individuals withdraw from societal roles, which is not evident in the active engagement of residents in different age-specific communities. Choice D (Social exchange theory) emphasizes the relationships individuals form based on rewards and costs, which is not the primary focus in the scenario compared to the age-based stratification.

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.
