Rationale: Maintaining chairmanship of the hospital nursing council demonstrates leadership and professionalism. This role involves overseeing and leading nursing activities at the hospital, showcasing a high level of responsibility and professionalism. Choices A, C, and D do not directly relate to demonstrating professionalism. Contributing money to a professional society, documenting the nursing process, or developing policy initiatives, while valuable activities, do not directly reflect the same level of leadership and professionalism as maintaining chairmanship.

Correct Answer: A

Rationale: The correct answer is A: Hepatotoxicity. Isoniazid (INH) can lead to hepatotoxicity, necessitating the monitoring of liver function tests. This adverse effect is characterized by liver damage and dysfunction. Choices B, C, and D are incorrect because isoniazid is not typically associated with hyperglycemia, hypotension, or hypokalemia. Therefore, the nurse should focus on assessing for signs and symptoms of hepatotoxicity in a client receiving isoniazid.

Correct Answer: A

Rationale: The correct answer is A because ensuring someone is responsible for the patient is crucial for continuous care. The presence of a caregiver during the nurse's absence ensures the patient's safety and well-being. Choice B, economic level of the family, is important but not the major point when planning nursing care in the home. Choice C, the availability of the nearest hospital, is significant but doesn't address the day-to-day care in the home. Choice D, whether or not the patient is under a private physician, is relevant but not as critical as ensuring someone is available to care for the patient at all times.

Correct Answer: A

Rationale: The correct answer is A. A community adopting a no smoking policy is a positive outcome for the Leading Health Indicators of Healthy People 2020 as it promotes a healthier environment by reducing exposure to secondhand smoke and decreasing smoking-related illnesses. Choices B, C, and D do not directly align with the goals of the Leading Health Indicators. While public transportation and reduced dropout rates are beneficial for community well-being, they are not specific examples of Leading Health Indicators. Decreasing divorce rates, while potentially beneficial for family stability, is not a focus area of the Leading Health Indicators.

Correct Answer: B

Rationale: Restlessness and confusion are signs of hypoxia and hypercapnia in a client with COPD, indicating that the client's condition may be deteriorating rapidly. Immediate attention is necessary to prevent further complications. Nausea and vomiting (Choice A) may be related to various factors but do not directly indicate respiratory distress. Low-grade fever and cough (Choice C) are common in COPD and may not require immediate intervention. Irritating cough and liquefied sputum (Choice D) are typical symptoms of COPD exacerbation but do not signal an immediate need for attention as restlessness and confusion.
