During the COVID-19 pandemic, a public health department wanted to introduce a smartphone application

Correct Answer: D

Rationale: The correct answer is D: Relative advantage. In the context of the diffusion of innovations theory, relative advantage refers to the perceived improvement of an innovation over existing solutions. During the COVID-19 pandemic, the public health department needed to demonstrate that the smartphone application offered clear benefits compared to other methods of contact tracing or information dissemination. This is crucial for gaining widespread acceptance and adoption. Incorrect choices: A: Trialability - While trialability is important for encouraging adoption by allowing individuals to experiment with the innovation, it does not directly address the perceived advantages of the smartphone application. B: Observability - Observability relates to the visibility of the innovation's results, which may influence adoption but does not directly address the comparative benefits of the smartphone application.

Correct Answer: B

Rationale: Step-by-step rationale for why choice B is correct: 1. Determining responsibilities of each partner is crucial to ensure clarity and accountability within the coalition. 2. Clear responsibilities help in establishing expectations and ensuring effective collaboration. 3. This step aids in defining roles, tasks, and contributions of each partner, leading to efficient partnership agreements. 4. Without clearly defined responsibilities, partners may have misunderstandings and conflicts, hindering the coalition's progress. Summary of why other choices are incorrect: A: Identifying potential partners is part of step 2, not step 3. C: Developing a shared purpose is usually done in the initial stages before partnership agreements. D: Communicating evaluation results is important but typically comes after partnership agreements are established.

Correct Answer: D

Rationale: The correct answer is D: Level of education. Nurses assess education levels to determine social determinants of health as higher education can lead to better health outcomes. Age (A), physical activity (B), and nutrition (C) are important factors, but they do not directly reflect the social determinants of health in a community. Education is a key social determinant as it influences access to resources, employment opportunities, income levels, and health literacy. Understanding education levels helps nurses identify disparities and develop targeted interventions to improve overall community health.

Correct Answer: A

Rationale: The correct answer is A because in the START triage system, immediate or red category is assigned to victims who are in critical condition and require immediate intervention to survive. A victim who is not breathing after two attempts to open the airway falls under this category as they need immediate attention to establish an airway and start breathing. Choice B is incorrect as a broken arm, while painful, does not pose an immediate life-threatening situation. Choice C is incorrect as multiple lacerations, although serious, do not indicate immediate life-threatening conditions. Choice D is also incorrect as a respiratory rate greater than 30 beats/minute with flail chest may be serious but does not require immediate intervention as compared to a victim who is not breathing.

Correct Answer: B

Rationale: The correct answer is B because highly transmissible Category A biological agents pose a significant risk of spreading rapidly in the community. This characteristic guides the nurse's actions to implement strict infection control measures, isolation protocols, and public health interventions to contain the outbreak. Choice A is incorrect as low mortality rates do not necessarily indicate the level of threat or necessary interventions. Choice D is incorrect as Category A agents are considered a threat to public health. Choice C is omitted.
