Which of the following is a matter of public, not private, law?

Correct Answer: D

Rationale: The correct answer is D, 'Licensing of a home health agency.' Public law governs relationships between private parties and the government, such as licensing requirements for entities like home health agencies. Choices A, B, and C involve private law, which governs relationships between individuals and organizations. These choices pertain to wrongful acts against another party, invasion of privacy, and assault and battery, respectively.

Correct Answer: C

Rationale: A standard of care is the level of care that a reasonably prudent person with similar training and experience would provide in a similar circumstance. Choice A is incorrect because it describes the nurse-patient relationship. Choice B is incorrect as it refers to specific policies or procedures. Choice D is incorrect as it describes a law rather than the expected level of care.

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: 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: B

Rationale: Nurses may not have the medical expertise to answer all the questions that patients may have regarding their treatment, which is a crucial aspect of obtaining informed consent. While nurses should not influence a patient's decision, it is not a major reason why they should not obtain informed consent. Signatures obtained by nurses are legally binding, and although nurses often act as witnesses, there is no legal restriction preventing them from obtaining informed consent itself.
