Correct Answer: B

Rationale: Nurses may not have the medical expertise to answer all the questions that patients may have regarding their treatment, which is a crucial aspect of obtaining informed consent. While nurses should not influence a patient's decision, it is not a major reason why they should not obtain informed consent. Signatures obtained by nurses are legally binding, and although nurses often act as witnesses, there is no legal restriction preventing them from obtaining informed consent itself.

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: A durable power of attorney allows competent individuals to appoint someone else to make decisions on their behalf in the event they become incompetent. Choice A is incorrect because a durable power of attorney is typically granted by the individual themselves, not the court. Choice C is incorrect as a durable power of attorney can be effective both before and after incompetency. Choice D is incorrect because managing financial assets is just one aspect of the authority granted by a power of attorney, not specifically for a durable power of attorney.

Correct Answer: B

Rationale: The correct answer is B because understanding the impact of culture on health and illness enables nurses to provide individualized and culturally sensitive care to older adults from diverse backgrounds. This approach ensures that the cultural, religious, and sexual orientation differences of older adults are acknowledged, respected, and factored into their care. Choice A is not as comprehensive as B, as the goal goes beyond just respecting customary practices. Choice C, while important, is more focused on medical treatments rather than holistic care. Choice D is not the primary reason for understanding culture; the main goal is to provide personalized care that respects individual differences.

Correct Answer: D

Rationale: In this scenario, Nurse B faces a high risk of liability for his actions due to several factors. Working with insufficient resources, failing to adhere to policies and procedures, taking shortcuts, and working while highly stressed are all situations that increase the risk of liability. Nurse B's decision to lift an obese patient without assistance and skip the patient's evening bath due to time constraints and lack of help are clear examples of actions that can lead to legal consequences. Choices A, B, and C are incorrect because the circumstances described in the scenario indicate a higher likelihood of liability due to the factors mentioned above.
