What is the most common cause of delirium in hospitalized older adults?

Correct Answer: C

Rationale: The correct answer is C: Urinary tract infections (UTIs). UTIs are a common cause of delirium in hospitalized older adults due to their impact on the central nervous system. UTIs can lead to systemic inflammation and affect cognitive function, resulting in delirium. Other choices like medication side effects, sleep deprivation, and electrolyte imbalances can contribute to delirium but are not as common or direct as UTIs in this population.

Correct Answer: A

Rationale: The correct answer is A: Regular repositioning every 2 hours. Repositioning helps to relieve pressure on vulnerable areas, improving blood flow and preventing tissue damage. This intervention is evidence-based and recommended in pressure ulcer prevention guidelines. Administering pain medications before repositioning (B) does not address the root cause of pressure ulcers. Encouraging excessive hydration (C) may have other health benefits but does not directly prevent pressure ulcers. Using restrictive bandages (D) can actually increase pressure and worsen the risk of pressure ulcers.

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: D

Rationale: The correct answer is D because promoting independence without assistance to all clients may not always maintain safety for the elderly. Elderly individuals may require some level of assistance for certain activities to prevent falls or other safety risks. Providing assistance when needed is crucial for ensuring their safety. A: Modifying the environment to reduce obstacles and barriers to ambulation helps prevent falls. B: Consistent checks of ambulation abilities ensure early detection of any decline in mobility. C: Orienting to new surroundings and repeating as needed helps prevent confusion and disorientation.

Correct Answer: C

Rationale: The correct answer is C because gerontological nursing focuses on promoting health and maximizing independence in older adults. This statement aligns with the core principles of gerontological nursing, which emphasize holistic care and quality of life for elderly individuals. Choice A is incorrect because nurses have been involved in caring for older adults for a long time. Choice B is incorrect because gerontological care was not the second specialty certified by the ANA. Choice D is incorrect because ANA certification is not limited only to research positions in gerontological nursing.
