Which of the following actions would a nurse take to reduce the high incidence of coronary

Correct Answer: B

Rationale: The correct answer is B because it addresses prevention strategies at different levels: starting early with education in schools, reaching the general community with diet and exercise presentations, and targeting high-risk groups with specialized sessions. This comprehensive approach tackles the issue from multiple angles, promoting long-term behavior change and awareness. Choice A lacks specificity and does not provide a comprehensive plan to target different segments of the population. Choice C focuses mainly on online activities and screenings but lacks the community-wide educational aspect. Choice D includes some good elements like handouts and screenings but lacks the early intervention in schools and comprehensive community education approach present in choice B.

Correct Answer: D

Rationale: The correct answer is D: Encourage the parents to enroll their sons in Cub Scouts. The rationale for this is that the nurse should be promoting activities that have a positive impact on the children's development, such as Cub Scouts. Cub Scouts provide opportunities for social interaction, skill-building, leadership development, and community involvement. By encouraging the parents to enroll their sons in Cub Scouts, the nurse is supporting their holistic growth and well-being. Choice A is incorrect because it is unrelated to the nurse's role and does not address the children's well-being. Choice B is incorrect as it discourages a potentially beneficial activity without valid reasoning. Choice C is incorrect as it dismisses the potential benefits of Cub Scouts and does not consider the children's overall development.

Correct Answer: C

Rationale: The correct answer is C: Host factors. Host factors refer to individual characteristics that influence susceptibility to a particular disease. In this scenario, the variation in illness among those exposed to the same bacteria suggests that host factors play a crucial role. Factors such as immune status, genetic predisposition, age, and overall health can affect an individual's ability to combat the bacterial illness. This explains why only some of the exposed individuals became ill. A: Chemical agent factors - This choice refers to agents like toxic chemicals, which are not directly relevant to the scenario described. B: Environmental factors - While environmental factors can play a role in disease transmission, the question specifically focuses on why only some individuals became ill despite exposure to the same bacteria. D: Physical agent factors - This choice relates to physical agents like radiation or trauma, which are not applicable to a bacterial illness scenario.

Correct Answer: B

Rationale: The correct answer is B because having a plausible explanation of how the new MCP could cause harm is essential to confidently present concerns to administration. This step involves understanding the potential mechanisms by which the MCP may be causing issues, providing a logical basis for the observed problems. Without a clear explanation, it would be challenging to convince administration of the causal link. Choices A, C, and D are incorrect: A: Merely having certain conditions present doesn't provide a solid foundation for presenting concerns without a plausible explanation. C: Relying solely on feelings without concrete evidence or reasoning is not sufficient to support the claim. D: While consistently seeing mouth inflammation is concerning, without understanding how the MCP could be causing it, it lacks a logical basis for presenting the issue to administration.

Correct Answer: C

Rationale: The correct answer is C: Cohort study. In a cohort study, the public health nurse follows a group of individuals over time to assess the relationship between exposure and disease occurrence. This type of study allows for the determination of potential cause and effect relationships. In contrast, an experimental study (choice A) involves intervention and manipulation of variables. A cross-sectional study (choice B) captures data at a single point in time without following individuals over time. A case-control study (choice D) involves comparing individuals with and without a disease to identify factors associated with the disease but does not provide information on the temporal sequence of exposure and disease occurrence.
