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: B

Rationale: In the management of acute respiratory infection in a child, it is essential to address various aspects of care. Providing safe remedies to relieve symptoms like sore throat and cough (Choice A) helps in managing discomfort. Advising the mother to monitor for signs of pneumonia (Choice C) is crucial for early detection and intervention if complications arise. Ensuring proper nutrition (Choice D) is important for the child's overall health and immune function during illness. Therefore, all the listed interventions are appropriate in managing acute respiratory infection, making Choice B the correct answer. Choices A, C, and D are incorrect on their own as they address only specific aspects of care and not the comprehensive management of acute respiratory infection.

Correct Answer: B

Rationale: The correct answer is B: Left ventricular end-diastolic pressure. Pulmonary capillary wedge pressure is used to assess left ventricular end-diastolic pressure. This measurement provides valuable information on the filling pressure of the left ventricle. Choices A, C, and D are incorrect because monitoring pulmonary capillary wedge pressure does not directly assess right ventricular pressure, acid-base balance, or coronary artery stability.

Correct Answer: A

Rationale: The correct initial response for the nurse to provide in this situation is to offer reassurance. Stating that 'Pheochromocytomas usually aren't cancerous (malignant)' helps to alleviate the client's anxiety and fear of having cancer. This response also establishes a foundation for further discussion about the condition, allowing the nurse to address the client's concerns and provide accurate information. Choice B is incorrect as it focuses solely on the diagnostic tests for pheochromocytoma but does not address the client's emotional distress. Choice C is incorrect as it discusses imaging modalities without directly addressing the client's concerns. Choice D is also incorrect as it assumes symptoms without first addressing the client's emotional state and fear of cancer.

Correct Answer: C

Rationale: Studying knowledge, attitudes, and practices of the people is the best method to determine appropriate health teaching for a community. This approach provides valuable insights into the specific needs, beliefs, and behaviors of the population, allowing for tailored and effective health education interventions. Interviewing midwives may offer some insights, but focusing on the broader community is more comprehensive. Reviewing records and reports can provide historical data but may not capture current community needs as effectively as studying current knowledge, attitudes, and practices. Reviewing health statistics is important but may not provide the detailed understanding of community perceptions and behaviors that directly impact health education planning.
