Correct Answer: B

Rationale: The correct answer is to monitor the patient's daily weight. In heart failure, sudden weight gain indicates fluid retention, which can worsen the condition. Monitoring daily weight helps in early detection of fluid accumulation, allowing timely intervention. Restricting fluid intake (choice A) may be necessary but is not the priority at this point. Administering diuretics (choice C) should be done based on healthcare provider orders, not the nurse's independent decision. Increasing salt intake (choice D) is contraindicated in heart failure as it can exacerbate fluid retention.

Correct Answer: B

Rationale: If a nurse manager assigns a nursing assistant a task that is outside of their role, the nursing assistant should report the task to the charge nurse. This is important because the charge nurse can provide guidance on whether the task is appropriate for the nursing assistant to perform. Choice A is incorrect because blindly following a directive that is outside of the nursing assistant's scope could lead to negative consequences. Choice C might not be the best course of action initially, as it's important to seek clarification first. Choice D is also not the best option because performing a task outside of one's role without proper authorization can pose risks to both the patient and the nursing assistant.

Correct Answer: B

Rationale: The correct answer is B. The nurse must follow the legal DNR order, even if the family insists on resuscitation. Respecting the patient's wishes is crucial in providing ethical care. Choice A is incorrect because the nurse should prioritize the patient's documented wishes over the family's requests. Choice C may cause unnecessary delays in care as the DNR order is a legal document. Choice D is not the initial action to take in this situation; the nurse should first address the conflict between the family's wishes and the patient's DNR order.

Correct Answer: B

Rationale: Reporting the behavior to the nurse manager immediately is the most appropriate action when a nurse suspects a colleague of being impaired while on duty. This is crucial to ensure patient safety and maintain a professional and safe work environment. Speaking to the colleague in private may not address the issue effectively and could potentially put patients at risk if the colleague is indeed impaired. Confronting the colleague directly on the floor may lead to a confrontation and is not the most professional way to handle the situation. Doing nothing and documenting the situation without taking immediate action can jeopardize patient safety and is not an appropriate response when substance use is suspected.

Correct Answer: D

Rationale: During a potential bioterrorism attack, the priority for the nurse is to manage all patients using standard precautions. This approach ensures the safety of both patients and healthcare providers by preventing the spread of potential bioterrorism-related illnesses. Option A is incorrect because managing patient care and safety through standard precautions takes precedence. Option B is incorrect as patient transport should also be done while adhering to infection control measures. Option C is incorrect as monitoring for specific symptoms is important but not the priority when all patients need to be managed with standard precautions.
