Which activity by the nurse supports the core function of assurance in public health?

Correct Answer: B

Rationale: The correct answer is B because developing policies in collaboration with an interprofessional team supports the core function of assurance by ensuring that necessary regulations and standards are in place to protect and promote public health. This activity helps guarantee that health services are delivered effectively and efficiently. Surveying a population (choice A) focuses more on assessment rather than assurance. Monitoring health data trends (choice C) is essential for assessment and policy development but does not directly address the assurance function. Ensuring access to health services for all (choice D) relates more to the core function of accessibility rather than assurance.

Correct Answer: C

Rationale: Step 1: Defining a scope of practice for nurses ensures they work within their level of qualification, expertise, and competence, promoting safe and effective patient care. Step 2: It helps prevent nurses from performing tasks beyond their training, reducing the risk of errors and harm to patients. Step 3: By clearly outlining what nurses can and cannot do, it provides clarity and accountability in their practice. Step 4: This supports professional development by encouraging ongoing education and training to expand their scope as they gain experience. Step 5: Choices A, B, and D are incorrect because while they are important aspects of nursing practice, they do not directly address the main purpose of defining a scope of practice, which is to ensure nurses work within their level of qualification and competence to protect patient safety.

Correct Answer: B

Rationale: The correct answer is B: Cultural competency. When hiring a workforce representative of the community, the nurse must understand and respect cultural differences to effectively engage with diverse populations. This falls under the Cultural competency domain, which focuses on recognizing, respecting, and incorporating cultural beliefs and practices into nursing practice. A: Communication - While important, hiring a diverse workforce goes beyond communication skills. C: Community dimensions of practice - This domain focuses on understanding the community as a whole, not specifically on hiring practices. D: Leadership and systems thinking - This domain emphasizes leadership skills and understanding of healthcare systems, which are not directly related to hiring a culturally representative workforce.

Correct Answer: B

Rationale: The correct answer is B: Primary prevention. Primary prevention aims to prevent the onset of a disease or injury before it occurs. In this scenario, the nurse is providing bike safety tips to children to prevent accidents from happening in the first place. Primordial prevention focuses on addressing social determinants of health before risk factors develop, which is not the case here. Secondary prevention involves early detection and treatment of a disease or injury, which does not align with the nurse's role in providing safety tips. Tertiary prevention involves managing and treating existing conditions to prevent complications, which is not the focus of the nurse's intervention in promoting bike safety for children.

Correct Answer: B

Rationale: The correct answer is B because attending meetings of various health agencies allows the nurse to stay informed about current health issues, collaborate with other professionals, and advocate for public health policies. This role involves networking, sharing information, and influencing decisions at a higher level. A is incorrect as it focuses on a specific community issue rather than the broader role of a public health nurse. C is incorrect as it is limited to individual health concerns, not the population-level focus of a public health nurse. D is incorrect as watching a city council meeting does not actively engage in the duties of a public health nurse.
