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: 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: B

Rationale: An informed consent may be considered invalid if the patient does not fully understand what he or she is signing. Patients with a fluctuating level of mental function are incapable of granting legally sound consent. Nurse M could be held liable for a violation of Mr. Y's rights as he did not have the capacity to provide informed consent. The presence of an insurance policy and the legal status of family members are irrelevant in this context and do not absolve Nurse M of potential liability.

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: A

Rationale: In this scenario, the nurse should respect the father's perspective and accept that the relationship with his common-law partner may indeed be positive and beneficial for him. The nurse's role is to support the patient's autonomy and decisions, especially when there are no legal concerns or signs of abuse. Organizing a family meeting (Choice B) might be premature without first acknowledging the father's viewpoint. Documenting concerns and investigating (Choice C) may create unnecessary conflict and breach the father's trust. Asking the partner to prove herself (Choice D) could strain the relationship further and is not within the nurse's role unless there are clear signs of harm or abuse.
