Which statement about Salmonella made in a class about disease prevention indicates that additional teaching is needed?

Correct Answer: C

Rationale: The correct answer is C because Salmonella is not typically spread through blood exposure. Step 1: Salmonella is primarily transmitted through contaminated food or water. Step 2: Person-to-person contact and carrier animals are known modes of transmission. Step 3: Outbreaks are commonly linked to contaminated meat, poultry, and eggs. In contrast, spreading through blood is not a significant route of transmission for Salmonella. Other choices are incorrect because they align with established knowledge about Salmonella transmission.

Correct Answer: A

Rationale: The correct answer is A because collecting blood specimens from preschool children to check for lead levels is an example of secondary prevention, which aims to detect and treat health problems early. This action helps identify children at risk for lead exposure and allows for early intervention to prevent further health issues. Choice B is incorrect because meeting with local government officials to request cleanup is more of a primary prevention strategy aimed at preventing exposure to environmental hazards in the first place. Choice C is incorrect as it involves tertiary prevention, focusing on treatment and management of existing health problems. Choice D is incorrect as it pertains to primary prevention by educating parents about lead exposure risks.

Correct Answer: C

Rationale: The correct answer is C: Check the most recent report on water quality in the community. This is the best action as it allows the CHN to gather factual information on the water quality before taking further steps. By reviewing the report, the CHN can determine if there are any concerning findings that may explain the unusual taste. Advocating or lobbying (Choice A) may be necessary later on, but it's important to first gather evidence. Consulting CPCHE (Choice B) may provide useful information, but checking the local water quality report is more direct. Calling the poison control centre (Choice D) is not necessary unless there is evidence of immediate harm, which is not indicated in the scenario.

Correct Answer: B

Rationale: The correct answer is B: Reduce, reuse, recycle, recover. 1. Reduce: Minimizing the generation of waste or pollution at the source is the most effective way to manage risks. 2. Reuse: Extending the life of products by using them multiple times reduces the need for new production, further reducing risks. 3. Recycle: Processing waste materials into new products helps reduce the environmental impact of resource extraction and manufacturing. 4. Recover: Extracting useful materials or energy from waste that cannot be reduced, reused, or recycled is a final step in managing risks. Summary: A: Incorrect. "Reproduce" and "redeliver" are not part of the typical risk management strategies related to environmental pollution. C: Incorrect. "Review" is not an action for reducing risks, and the order of actions is different from the standard reduce, reuse, recycle, recover approach. D: Incorrect. "Report" is not a direct action for reducing risks related to

Correct Answer: C

Rationale: The purpose of disaster planning is to manage the response to disasters. This involves preparing and organizing resources, systems, and procedures to effectively respond to and recover from disasters. It does not aim to decrease global instability (choice A), disrupt community functioning (choice B), or prevent disasters (choice D). Disaster planning focuses on minimizing the impact of disasters through efficient coordination and preparedness, making choice C the correct answer.
