Correct Answer: A

Rationale: The correct answer is A: Autonomy. Autonomy is the ethical principle that respects an individual's right to make decisions about their own care and treatment. In this scenario, the partner wanting "everything done" regardless of the patient's wishes violates the patient's autonomy by not honoring their previously expressed wishes outlined in the living will. This decision disregards the patient's right to make choices about their own healthcare. Choices B, C, and D are incorrect because: B: Beneficence focuses on doing good for the patient, but in this case, the partner's actions are not necessarily in the patient's best interest. C: Justice pertains to fairness and equal treatment, which is not directly relevant to the situation described. D: Nonmaleficence is the principle of doing no harm, but in this scenario, the harm is not necessarily physical but rather a violation of the patient's autonomy.

Correct Answer: B

Rationale: The correct answer is B because effective communication ensures that the patient's wishes and values are understood and respected, leading to informed decision-making. It also promotes shared decision-making among the patient, family, and healthcare team, enhancing the quality of care. Choices A, C, and D are incorrect because while they are important aspects of end-of-life care, they do not address the core element of communication in facilitating meaningful and informed decisions.

Correct Answer: D

Rationale: The correct answer is D, The Joint Commission, because it is a regulatory body that accredits healthcare organizations and requires them to have mechanisms for addressing ethical issues to ensure patient safety and quality of care. The other choices (A, B, C) are professional organizations that focus on specific areas of healthcare practice and do not have the authority to set regulatory standards for addressing ethical issues in healthcare organizations.

Correct Answer: B

Rationale: The correct short-term goal for the client with imbalanced nutrition is choice B: Eat 50% of six small meals each day by the end of one week. This goal is specific, measurable, achievable, relevant, and time-bound (SMART). By setting a goal for the client to eat a specific amount of meals within a defined timeframe, it allows for objective monitoring of progress. This goal also addresses the client's decreased intake and aims to improve their nutritional status gradually. Choice A is incorrect as verbalizing understanding does not directly address the client's nutritional needs. Choice C is not appropriate as it does not promote independence in meal consumption. Choice D is not the best short-term goal as it focuses on the outcome of weight gain rather than the process of increasing food intake. Overall, choice B is the most appropriate short-term goal as it targets the client's specific nutritional needs and provides a clear direction for intervention.

Correct Answer: B

Rationale: The correct answer is B because peritoneal dialysis utilizes the patient's own semipermeable membrane, the peritoneal membrane, as the filtration surface. This allows for the exchange of waste products and excess fluids without the need for external dialysis equipment. Choice A is incorrect as peritoneal dialysis can be used for both acute and chronic kidney injury. Choice C is incorrect as peritoneal dialysis can help manage drug overdose and electrolyte imbalances. Choice D is incorrect as peritoneal dialysis can be used in cases of water intoxication to help remove excess fluids.
