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: B

Rationale: Hypertension is disproportionately high among Native American/First Nations clients. This condition is not noted to be a major health problem among Jewish Americans, prisoners, or Americans of Chinese ancestry. Developing a screening program for hypertension in a Native American reservation/Canadian aboriginal reserve would be most appropriate based on the prevalence of the condition in this population.

Correct Answer: C

Rationale: The correct answer is C. Residents in long-term care settings often have limited food choices, which may not align with their cultural preferences. When assessing why a client is refusing to eat, it is essential to consider if the food served is culturally appropriate. Choices A, B, and D are incorrect. There is no indication in the scenario that the client's refusal to eat is due to not liking to eat with other residents, using it as an excuse to go home, or violating religious beliefs.

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.

Correct Answer: B

Rationale: The correct answer is B: heart disease. Heart disease is a major health issue among Native American/First Nations populations, along with diabetes, malignant neoplasm, and unintentional injuries, contributing to a decreased lifespan. Autoimmune disorders, Alzheimer's disease, and lung cancer are not the primary health concerns that the nurse should monitor for in this client. By understanding the prevalent health issues in this population, the nurse can provide targeted care and interventions to promote better health outcomes.
