Correct Answer: D

Rationale: The correct answer is D because assisting residents with ambulation to meals promotes physical activity, which is known to reduce the risk of Alzheimer's disease. Physical activity increases blood flow to the brain, reduces inflammation, and promotes the growth of new brain cells. Keeping curtains open (choice A) may offer natural light but does not directly reduce the risk of AD. Offering beads for stringing (choice B) and showing movies (choice C) may provide cognitive stimulation but do not address the physical activity needed to decrease the risk of AD.

Correct Answer: D

Rationale: The correct answer is D: Age-related changes in liver function. As people age, there are changes in liver metabolism and blood flow, affecting the processing of anesthetic agents. Liver function declines with age, leading to slower drug metabolism and clearance, increasing the risk of adverse reactions. Decreased muscle mass (A) may affect drug distribution but not metabolism. Decreased renal function (B) can impact drug excretion but is not the primary reason for adverse reactions. Increased body fat (C) can alter drug distribution but is not the main factor in anesthesia reactions for older adults.

Correct Answer: C

Rationale: The correct answer is C: Monitoring for electrolyte imbalances and adjusting medications accordingly. In advanced CKD, electrolyte imbalances can worsen kidney function and lead to complications. Monitoring electrolytes like potassium and adjusting medications such as diuretics is crucial. A: Initiating early dialysis is not always necessary and should be based on individual patient factors. B: Avoiding all medications is not feasible as some medications are essential and can be adjusted based on kidney function. D: Limiting fluid intake to less than 500 mL per day is too restrictive and can lead to dehydration.

Correct Answer: A

Rationale: The correct answer is A because social aging refers to changes in a person's roles and relationships as they age. Retiring from a job is a significant social change that typically accompanies aging. This indicates a shift in the man's social status and activities, which aligns with the concept of social aging. B, C, and D are incorrect because taking multiple medications, using a walker, and celebrating a 65th birthday are not direct indicators of social aging. While these factors may be related to aging, they do not specifically address the social aspects of aging, which is the focus of the question.

Correct Answer: B

Rationale: The correct answer is B because older adults with chronic conditions are often prescribed multiple medications to manage their various health issues, leading to polypharmacy and increased risk of adverse drug reactions. This challenge can result in medication mismanagement, drug interactions, and medication non-adherence. The other choices are incorrect because comorbidities are common in older adults, medical intervention is generally accepted, and older adults often experience declines in physical and cognitive health with age.
