Correct Answer: D

Rationale: The correct answer is D, incidence rate. Incidence rate measures the frequency of new cases of a phenomenon, providing important information about the risk of developing the condition. Prevalence rate (choice A) reflects both old and new cases, proportionate mortality rate (choice B) is the proportion of deaths due to a specific cause, and case fatality rate (choice C) measures the proportion of deaths among confirmed cases, not just new cases.

Correct Answer: C

Rationale: Health activities are structured to enhance communities' autonomy and influence over their health and well-being, aiming to empower them to make informed choices and take control of their health. Choice A is incorrect as health activities encompass a broader scope beyond just preventing exposure to germs. Choice B is incorrect because spiritual factors are crucial components that should not be disregarded in healthcare. Choice D is incorrect as health activities are not solely about the community health nurse being in charge, but about empowering the community as a whole.

Correct Answer: C

Rationale: The correct topic that the nurse should include in planning a primary prevention class for adolescents is suicide risks and prevention. Adolescents are particularly vulnerable to mental health issues, including suicidal ideation. Educating them about suicide risks and prevention strategies is crucial for early intervention and support. Choices A, B, and D are important topics, but when considering primary prevention for adolescents, addressing suicide risks and prevention takes precedence due to its immediate life-saving implications.

Correct Answer: D

Rationale: The correct answer is D: upstream intervention. Upstream thinking addresses the root causes of health problems to create long-term solutions. In this scenario, requiring the incinerator to install particulate filters tackles the root cause of asthma triggers, which is pollution, rather than just managing the symptoms or risks associated with asthma. Choice A, downstream intervention, would focus more on treating asthma symptoms after they have already occurred rather than preventing them. Choice B, risk management, typically involves strategies to assess, control, or mitigate risks, which may not directly address the root cause. Choice C, primary prevention, usually refers to actions taken to prevent a disease or condition before it occurs, but in this case, the action is targeting the underlying cause rather than preventing asthma itself.

Correct Answer: D

Rationale: The client's symptoms of shortness of breath, headache, dizziness, and nausea are indicative of carbon monoxide poisoning, which can result from exposure to gasoline-powered equipment like pressure washers. Asbestos (Choice A) exposure would typically present with respiratory issues and cancer but not the rapid onset of symptoms described. Silica dust (Choice B) exposure is associated with respiratory conditions like silicosis, not the multisystem symptoms in the scenario. Histoplasmosis (Choice C) is a fungal infection that primarily affects the lungs and is not related to the client's exposure to a gasoline-powered pressure washer.
