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

Correct Answer: B

Rationale: Step 1: Introduction of heart-healthy curriculum in first grade instills early awareness and habits. Step 2: Presentations on diet and exercise educate the community on preventive measures. Step 3: Special education sessions for high-risk populations target those most vulnerable. Summary: Choice A lacks specificity and targeted approach. Choice C focuses mainly on online activities, lacking community engagement. Choice D includes some good elements but lacks a comprehensive and early intervention approach like Choice B.

Correct Answer: D

Rationale: The correct answer is D: Encourage the parents to enroll their sons in Cub Scouts. The nurse should recommend this because Cub Scouts can provide a positive and enriching experience for the boys in terms of social skills, character development, and physical activities. It is relevant to the children's overall well-being and can contribute to their growth and development. Option A is incorrect as it does not address the benefits of joining Cub Scouts. Option B is incorrect as it discourages enrollment without considering the potential positive impact. Option C is incorrect as it dismisses the relevance of Cub Scouts without considering its potential benefits for the children.

Correct Answer: C

Rationale: The correct answer is C: Host factors. Host factors refer to individual characteristics that influence susceptibility to an infection. In this case, some people exposed to the bacteria may have stronger immune systems or other genetic predispositions that make them more resistant to the illness. This explains why only some individuals become ill despite exposure. A: Chemical agent factors are not relevant in this scenario as the question focuses on the individual's response to the bacteria rather than specific chemicals involved. B: Environmental factors may play a role in the spread of the bacteria but do not explain why only some individuals become ill. D: Physical agent factors typically refer to physical forces causing injury, which are not directly applicable to a bacterial illness scenario.

Correct Answer: B

Rationale: Rationale for Correct Answer (B): A plausible explanation of how the new MCP could cause harm is crucial for the nurse to confidently present concerns to administration. Without understanding how the MCP could be causing issues, it would be challenging to convince administration of the need for changes. This step ensures that the nurse has a solid basis for their argument and can clearly articulate the potential risks associated with the new procedure. Summary of Incorrect Choices: A: While having specific criteria present can strengthen the case, it is not the primary factor for determining if the MCP is causing problems. C: Relying solely on personal feelings or intuition is not sufficient evidence to support the claim that the MCP is causing harm. D: Observing consistent mouth inflammation is important but does not provide a clear causal relationship between the MCP and the issues, lacking the necessary explanation of how harm is being caused.

Correct Answer: C

Rationale: The correct answer is C: Cohort study. In a cohort study, participants are followed over time to evaluate the relationship between exposure/lifestyle factors and disease occurrence. This allows for the assessment of causality and temporal sequence. The public health nurse is collecting exposure and lifestyle information to observe how they influence disease development in the future. Cross-sectional studies (B) assess factors and outcomes at a single point in time, not over time like cohort studies. Experimental studies (A) involve interventions and randomization which is not the case here. Case-control studies (D) are retrospective and compare individuals with and without the disease, not following them over time like in a cohort study.
