Correct Answer: C

Rationale: The correct answer is C. The doctrine of respondent superior holds that supervisors are accountable not only for their own actions but also for the actions of the staff they oversee. This means that nurses, as supervisors, are responsible for ensuring that the actions of their staff comply with established protocols and standards of care. Choices A, B, and D are incorrect because they do not directly relate to the principle of respondent superior. Nurses may have other responsibilities related to giving advice, medication administration, and obtaining consent, but the doctrine of respondent superior specifically pertains to the accountability of supervisors for the actions of their subordinates.

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: C

Rationale: The correct answer is C. Usually, a power of attorney becomes invalid if the individual granting it becomes incompetent, except in the case of a durable power of attorney. A durable power of attorney allows competent individuals to appoint someone to make decisions on their behalf in the event that they become incompetent. This legal arrangement is recommended for individuals with conditions like Alzheimer's disease where competency decline can be anticipated. It is not initiated by the court, unlike guardianship. A durable power of attorney encompasses both logistical and financial affairs, providing authority to the appointed person to act on behalf of the individual should they become incapacitated. Choices A, B, and D are incorrect because they do not accurately describe the purpose and nature of a durable power of attorney in the context of planning for incompetency due to conditions like Alzheimer's disease.

Correct Answer: D

Rationale: The correct answer is D. Black older adults historically possess many health problems that have accumulated over a lifetime due to a poor standard of living and limited access to health care services. Option A is incorrect because it presents stereotypes about the black population that are not supported by evidence. Option B is incorrect because it generalizes the behavior of the white population without a strong basis. Option C is incorrect as it also generalizes the white population and does not address the disparities in health status between the two groups.

Correct Answer: D

Rationale: The correct answer is D. The Health Insurance Portability and Accountability Act (HIPAA) is a federal law that protects individuals' right to confidentiality and safeguards health information from being accessed by unauthorized individuals. Assuring the client that the law protects their right to confidentiality and prevents their health information from being released into unintended hands is the best response. Choice A is too broad and may not cover all aspects of confidentiality. Choice B only mentions medical records staying within the hospital, which does not address the client's concern about written documentation. Choice C incorrectly implies that a signed directive is needed for confidentiality, which is not true under HIPAA regulations.
