Correct Answer: B

Rationale: The correct answer is B because super-centenarians, who are individuals aged 110 years or older, often exhibit a high level of functional independence despite their advanced age. This is supported by research showing that many super-centenarians maintain physical and cognitive abilities that allow them to perform daily activities without significant assistance. This statement aligns with the concept of successful aging, where individuals maintain autonomy and independence in later years. Option A is incorrect because a significant number of super-centenarians are not dependent on full-time nursing care for daily activities. Option C is incorrect as many super-centenarians can still engage in social activities despite health limitations. Option D is incorrect as most super-centenarians do not experience severe cognitive decline that affects their daily living.

Correct Answer: C

Rationale: The correct answer is C: Pneumonia. Older adults are more susceptible to pneumonia due to weakened immune systems and underlying health conditions. Pneumonia can lead to severe complications, requiring hospitalization. Osteoarthritis (A) primarily affects joints and does not typically lead to hospitalization. Stroke (B) and heart failure (D) are serious conditions but may not be as common for hospitalization as pneumonia in older adults. Pneumonia's impact on the respiratory system and its ability to progress rapidly make it the most common reason for hospitalization in this population.

Correct Answer: B

Rationale: The correct answer is B: Delirium in older adults results from reversible metabolic changes, such as electrolyte imbalances. Delirium is a multifactorial condition often triggered by physiological imbalances, including electrolyte disturbances. These imbalances can disrupt normal brain function, leading to confusion and cognitive impairment. Other choices are incorrect: A is more typical of sepsis, C is more associated with conditions like dementia, and D is not a primary cause of delirium.

Correct Answer: D

Rationale: The correct answer is D. Ingesting excessive acetaminophen can lead to liver damage, not renal failure. Diabetes mellitus, prostate hypertrophy causing urinary obstruction, and heart failure are known to cause renal failure due to their effects on kidney function. Diabetic nephropathy can damage the kidneys over time, prostate hypertrophy can obstruct urine flow and lead to kidney damage, and heart failure can result in decreased blood flow to the kidneys, causing renal failure. Thus, D is the correct answer as it does not directly cause renal failure, unlike the other choices.
