A communicable disease outbreak has occurred in a town. At a town meeting with public health officials, a community health nurse (CHN) is asked to explain the phrase "virulent organism." What definition of virulence is correct?

Correct Answer: A

Rationale: Rationale for Correct Answer (A): Virulence refers to the ability of a pathogen to cause disease in a host. Choice A is correct because it specifically addresses the ability of the organism to circumvent or evade the host's immune system. This is crucial as it allows the pathogen to establish an infection and cause harm. By bypassing the immune response, the organism can replicate and spread within the host, leading to disease manifestation. Summary of Incorrect Choices: B: While invading major organ systems can contribute to virulence, it is not the defining characteristic of virulence. Many pathogens can cause disease without directly invading organs. C: While some virulent organisms produce toxins, this is not the sole defining factor of virulence. Not all virulent organisms produce toxins, and some toxins may not directly weaken the body. D: Producing severe physical reactions may be a consequence of virulence, but it is not the fundamental definition of virulence. Virulence is more about the pathogen's

Correct Answer: A

Rationale: The correct answer is A: Competing. This conflict resolution strategy is most concerned with the self or "I-ness" because it prioritizes one's own needs and goals over others. It involves assertively pursuing one's interests without considering the concerns of the other party. This approach is suitable in situations where quick decisions are needed or when one's goals are more important than maintaining relationships. Summary of other choices: B: Avoidance - This strategy involves ignoring or sidestepping the conflict, focusing on neither self nor others. C: Compromising - This strategy involves finding a middle ground where both parties give up some of their demands, sharing concerns. D: Accommodating - This strategy involves prioritizing the concerns of the other party over one's own, focusing more on "you-ness" than "I-ness."

Correct Answer: A

Rationale: The correct answer is A: Nova Scotia. Nova Scotia was the first province in Canada to establish a public health nursing service in 1908. This initiative was led by Jessie Ross, a pioneering public health nurse. Nova Scotia's early recognition of the importance of public health nursing laid the foundation for other provinces to follow suit. Summary: B: Ontario - Ontario established a public health nursing service in 1921, after Nova Scotia. C: British Columbia - British Columbia established a public health nursing service in 1919, after Nova Scotia. D: Manitoba - Manitoba established a public health nursing service in 1919, after Nova Scotia.

Correct Answer: A

Rationale: The correct answer is A because the statement indicates a lack of insight into his violent behavior by attributing the violence to external factors (work frustrations) rather than taking personal responsibility. Choice B shows remorse and acknowledges the harm caused. Choice C demonstrates awareness and a plan for managing anger. Choice D recognizes the link between alcohol and abusive behavior. Overall, A is the only statement that deflects accountability for the violence onto external factors, showing a lack of insight into personal responsibility.

Correct Answer: D

Rationale: The correct answer is D: Evaluation. In this phase, the CHN is assessing the effectiveness of the community-wide education intervention by examining blood lead levels in school-aged children after one year. Evaluation involves determining if the intervention achieved the desired outcomes. Assessment (A) is the initial data collection phase. Diagnosis (B) involves identifying health problems. Intervention (C) is the phase where actions are taken to address the identified health problems. In this scenario, the focus is on evaluating the impact of the intervention, making D the most appropriate term.

Correct Answer: D

Rationale: The correct answer is D because the CHN is empowering the women to engage in political action locally by encouraging them to write letters to their city council representatives to request funding for a driver and a van service. This action not only raises awareness of the women's needs but also actively involves them in advocating for a solution. A) Incorrect: This choice implies that the CHN is avoiding responsibility, which is not the case. The CHN is actively guiding the women on how to address their transportation issue. B) Incorrect: While the CHN may understand the women's concerns and needs, the main focus of her action is to mobilize the women to take political action, rather than simply acknowledging their concerns. C) Incorrect: Although expressing empathy, support, and concern are important aspects of nursing care, the primary action here is to empower the women to engage in political action, not just provide emotional support.

Correct Answer: A

Rationale: The correct answer is A because it addresses prevention strategies at multiple levels - early education in schools, community-wide awareness through presentations, and targeted education for high-risk populations. Introducing heart health information in Grade 1 can establish lifelong healthy habits. Presentations for the community will reach a wider audience, promoting awareness and behavior change. Special education sessions for high-risk populations ensure tailored interventions. Choice B focuses on online activities and screenings, which may not be as effective in reaching the entire population. Choice C includes some good components like educational materials and screenings but lacks the comprehensive approach of choice A. Choice D is more focused on treatment and management rather than prevention, which is not as effective in addressing the high prevalence of CAD in the region.

Correct Answer: B

Rationale: The correct answer is B because establishing a system of networks allows for a holistic approach to addressing the various needs of a structurally vulnerable population. By referring clients to different services like preventive care, acute illness care, and chronic treatment, their overall health and well-being can be better supported. Choice A is incorrect because it focuses on addressing multiple health concerns when clients present for treatment of an illness, which may not fully address the underlying systemic issues faced by a structurally vulnerable population. Choice C is incorrect as it only provides acute care services and sets up appointments for other concerns at discharge, which may not adequately meet the ongoing needs of a structurally vulnerable population. Choice D is incorrect because referring clients to specialists for specific health concerns may not address the broader range of social determinants of health that contribute to their vulnerability.

Correct Answer: C

Rationale: The correct answer is C: Community participation. Community development is most effective when community members actively engage in the process. Community participation fosters ownership, empowerment, and sustainability. It ensures that interventions are relevant, culturally appropriate, and supported by the community. Adequate funding (A) is important but without community participation, resources may not be utilized effectively. Appropriate location (B) is also crucial, but it does not guarantee community involvement. Professional expertise (D) is valuable, but without community input, interventions may not address the actual needs of the community.
