For which of the following is informed consent required?

Correct Answer: D

Rationale: Informed consent is required when asking a patient to participate in a research study, as mentioned in choice D. Choices A, B, and C involve routine care measures that do not require specific informed consent. Ordering a liquid diet, providing saline solution for dry nasal passages, or listening to a patient's personal secrets are part of standard care and do not typically necessitate formal consent beyond general consent for treatment.

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: A durable power of attorney allows competent individuals to appoint someone else to make decisions on their behalf in the event they become incompetent. Choice A is incorrect because a durable power of attorney is typically granted by the individual themselves, not the court. Choice C is incorrect as a durable power of attorney can be effective both before and after incompetency. Choice D is incorrect because managing financial assets is just one aspect of the authority granted by a power of attorney, not specifically for a durable power of attorney.

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: Questioning a doctor's written orders for medication. Under the doctrine of respondent superior, nurses can face liability risks for various actions. Permitting volunteers to move patients, using malfunctioning equipment, or tasking unqualified staff can pose liability risks. Questioning medication orders is a responsibility to ensure patient safety. It is crucial for nurses to clarify any doubts or raise concerns about medication orders to prevent potential harm to patients.
