Correct Answer: A

Rationale: The correct answer is A. Today, on average, women spend more time providing care for their aging parents than they did for their own children. While some men provide care for their wives, it is not the most common pattern. Family members, rather than public or private agencies, still provide the majority of care in a non-institutional environment, making option C incorrect. Also, caregiving in a residential or institutional environment is not the most common venue, thus choice D is inaccurate.

Correct Answer: A

Rationale: The correct answer is A. The key difference between guardianship and power of attorney is that the court appoints a guardian to make decisions on behalf of an individual who is deemed incompetent, while an individual grants a power of attorney to someone else to make decisions on their behalf when they are competent. Choice B is incorrect because both guardianship and power of attorney can apply to individuals who are competent or incompetent. Choice C is incorrect as guardians, like those with power of attorney, must act in the best interest of the individual they represent, and the level of oversight can vary. Choice D is incorrect as guardianship and power of attorney do not have fixed time limits; they remain in effect until revoked or ended by the appropriate legal process.

Correct Answer: D

Rationale: In this potential case of elder abuse, the nurse's priority should be taking measures to protect the patient's safety. The patient's health and well-being are at risk due to the son's refusal to administer the diuretic, which can lead to serious health complications. While improving family dynamics (choice A), educating the son (choice B), and legal actions (choice C) may be necessary in the long run, the immediate concern is ensuring the patient's safety and well-being.

Correct Answer: A

Rationale: Historically, black Americans have experienced a lower standard of living and less access to health care than their white counterparts, leading to a lower life expectancy. However, by the seventh decade of life, survival rates for black individuals begin to equal that of similarly aged white individuals. Choice B is incorrect as it indicates a higher life expectancy for black individuals, which is not supported by the information provided. Choice C is incorrect as it suggests a drastic decrease in life expectancy for black individuals, which is not in line with the trend described. Choice D is incorrect as it implies a temporary increase in life expectancy for black individuals until age 75, which is not supported by the information that survival rates begin to equal by the seventh decade.

Correct Answer: B

Rationale: An advance directive, or living will, is a legal document that specifies an individual's preferences for medical treatment if they are unable to communicate their wishes. The most important advantage of an advance directive is that it spares the family from having to make challenging decisions about terminal care on behalf of the patient. Choice A is incorrect because advance directives pertain to healthcare decisions, not property matters. Choice C is incorrect as it refers to a will for property distribution, which is a different legal document. Choice D is incorrect as advance directives are not related to appointing guardians but rather focus on healthcare decision-making.
