Correct Answer: A

Rationale: The correct answer is A: Skin testing for tuberculosis. In a community clinic serving migrant families, tuberculosis is a significant health concern due to close living conditions and potential exposure during migration. Skin testing for tuberculosis is crucial for secondary prevention as it helps in early detection and prevention of the spread of the disease within the community. Choices B, C, and D are important health screenings but may not be the priority in this specific population where tuberculosis poses a higher risk.

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: D

Rationale: The best strategy for the nurse to use when teaching insulin injection techniques to a newly diagnosed client with diabetes is to observe a return demonstration. This method ensures that the client can correctly perform the technique. Providing written pre and post tests (choice A) may assess knowledge but not application. Asking questions during practice (choice B) may help with understanding but not necessarily with the actual performance. Allowing another diabetic to assist (choice C) may provide peer support but does not guarantee correct technique demonstration.

Correct Answer: A

Rationale: The correct answer is 'manager.' In the job description provided, the role involves setting goals, formulating policy, and directing and evaluating health services, which aligns with the responsibilities of a manager. A 'researcher' primarily focuses on conducting research, a 'health educator' specializes in educating individuals about health-related topics, and a 'health promotion specialist' concentrates on promoting health and wellness initiatives. Therefore, 'manager' is the most suitable title for the described role.

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.
