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: 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. Ms. O's friends, who are elderly and cannot drive, ride buses to visit her. The social worker can help by finding easier transportation options for them. Not having family around, friends' visits can significantly impact Ms. O's well-being. It may be challenging for the friends to ask for help themselves, so the social worker can reach out to volunteer groups for assistance. Making friends at the dialysis center might not be feasible due to the nature of treatments. Asking other residents' families to bring her friends could burden them further and might deter them from helping. It's important to consider the friends' convenience and emotional support for Ms. O.

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: C

Rationale: Denying admission to residents with living wills or advance directives is not a legal safeguard measure and may be considered discriminatory. Measures like investigating liability insurance adequacy, ensuring adequate work by unlicensed staff, and assessing employee competence are all valid ways for nurses to protect themselves legally. These measures help in ensuring proper care, reducing risks, and maintaining a high standard of practice.
