Correct Answer: C

Rationale: The correct answer is C. The charge nurse should include information that the proxy can make treatment decisions if the client is under anesthesia. This is a key function of a durable power of attorney for health care. Choices A, B, and D are incorrect because a health care proxy's role is specifically related to making health care decisions, not financial decisions, legal issues, or decisions made under anesthesia.

Correct Answer: C

Rationale: The correct answer is C: Broiled skinless chicken breast with brown rice. This option is suitable for a client with chronic pancreatitis as it is a low-fat, high-protein meal. Clients with pancreatitis should avoid high-fat foods like creamer, margarine, and avocados, making options A, B, and D incorrect choices.

Correct Answer: D

Rationale: The correct answer is D, decreased platelet count. In disseminated intravascular coagulation (DIC), there is widespread activation of clotting factors leading to the formation of multiple blood clots throughout the body, which can deplete platelets. A decreased platelet count is a hallmark of DIC. Elevated hemoglobin (choice A) and elevated white blood cell count (choice B) are not specific indicators of DIC. While fibrinogen levels (choice C) can be decreased in DIC due to consumption, a decreased platelet count is a more specific and early sign of DIC development.

Correct Answer: A

Rationale: The correct answer is A: 'A statement that participants can leave the study at will.' This information is crucial to include in the informed document to ensure that participants are aware of their right to withdraw from the study at any time without any negative consequences. Choice B is incorrect because participants should not be assigned to experimental or control groups without their knowledge and consent. Choice C is incorrect because disclosing a list of clients participating in the study violates confidentiality. Choice D is incorrect as the description of the data evaluation framework is important but not as critical as ensuring participants know they can leave the study at will.

Correct Answer: A

Rationale: The correct action for the nurse to take when a client with a history of angina reports chest pain is to administer sublingual nitroglycerin every 5 minutes. Nitroglycerin helps dilate blood vessels, improving blood flow to the heart and relieving chest pain associated with angina. Aspirin is often given during a suspected heart attack, not for immediate relief of angina. Deep breathing exercises may be beneficial for anxiety or respiratory conditions but are not the first-line intervention for angina. Oxygen therapy is not the initial treatment for angina unless the client is hypoxic.
