Which statement describes the purpose of defining a scope of practice for nurses?

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: 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.

Correct Answer: C

Rationale: The correct answer is C: Assurance. Assurance involves ensuring essential community-oriented health services are available, accessible, and of high quality. This function focuses on making sure the necessary health services are provided to the community. Policy development (A) involves creating health policies, assessment (B) involves collecting and analyzing data to understand health issues, and scientific knowledge-based care (D) focuses on evidence-based healthcare delivery, but these functions do not specifically address the availability of essential community-oriented health services.

Correct Answer: A

Rationale: The correct answer is A because economic turmoil often leads to limited resources, prompting a shift towards population-focused services to maximize impact and efficiency. High-technology care can be costly and may not address broader community health needs. Choices B, C, and D focus on specific health issues rather than the overall commitment to population-focused services. Choice B pertains to infectious diseases, which can be addressed through targeted interventions. Choice C emphasizes a broader approach to healthcare but does not directly relate to commitment to population-focused services. Choice D addresses a specific threat rather than a general strategy for population health.
