Which scenario exemplifies the community health nurse's (CHN's) practice of secondary prevention to reduce environmental health risks?

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: Holistic thinking. This type of thinking involves considering the entire system or population as a whole, focusing on interconnections and relationships between different components. It looks at the big-picture perspective rather than individual parts. Collaborative thinking (A) involves working together with others, not necessarily focusing on the population as a whole. Upstream thinking (B) involves addressing root causes of issues before they occur, but it doesn't necessarily focus on the big-picture population perspective. Downstream thinking (D) focuses on addressing consequences or effects after they have occurred, rather than the broader population perspective. Therefore, holistic thinking best aligns with the macroscopic, big-picture population focus.

Correct Answer: B

Rationale: The correct answer is B because it directly assesses the impact of the program on reducing teen injury and death related to drunk driving. By comparing statistics before and after the program, we can determine its effectiveness. A: This question focuses on participant satisfaction, not the program's impact on reducing teen injury and death related to drunk driving. C: This question focuses on the amount of alcohol intake by teens, not the program's impact on reducing teen injury and death related to drunk driving. D: This question focuses on program implementation issues, not the program's impact on reducing teen injury and death related to drunk driving.

Correct Answer: B

Rationale: The correct answer is B: Harm reduction. Harm reduction focuses on minimizing the negative consequences of risky behaviors rather than trying to eliminate them completely. It recognizes that certain behaviors may be difficult to prevent entirely and aims to reduce harm associated with those behaviors. Health promotion (A) focuses on promoting overall health and well-being rather than specifically addressing harmful behaviors. Tertiary care (C) refers to specialized medical care for individuals with complex healthcare needs and is not directly related to modifying behaviors. Risk avoidance (D) involves completely avoiding risky behaviors rather than mitigating their potential harm.

Correct Answer: C

Rationale: The correct answer is C: Nurse entrepreneurs. Nurse entrepreneurs are community health nursing practice areas that often receive funding from the private sector through investments, grants, or business partnerships. Nurse entrepreneurs establish their own businesses to provide healthcare services, products, or solutions, which require financial support from private entities. Telenurses (A), Corrections nurses (B), and Street or outreach nurses (D) typically receive funding from public sources, such as government agencies or nonprofit organizations, rather than the private sector.
