Correct Answer: A

Rationale: The correct answer is A: International Classification of Diseases. The ICD is a system used worldwide to classify and code various health conditions and diseases. This system helps in standardizing the documentation and coding of diseases, which is essential for epidemiology, research, and healthcare management. Choices B, C, and D are incorrect as they do not represent the widely recognized meaning of the acronym ICD in medical terminology.

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: Obtaining a peripheral O2 saturation reading is the priority intervention in this scenario. It helps assess the client's oxygenation status quickly, which is crucial in a client with signs of respiratory distress, such as shortness of breath and bilateral pulmonary crackles. Ordering a chest X-ray (Choice A) may be necessary later but does not address the immediate need for oxygen assessment. Obtaining an order for a complete blood count (Choice C) is not the priority in this situation as it does not directly address the client's respiratory distress. Instructing the patient to stay in bed (Choice D) does not address the underlying issue of potential hypoxia and respiratory compromise.

Correct Answer: D

Rationale: Physical inactivity is a modifiable risk factor for chronic diseases because individuals have control over their level of physical activity. By increasing physical activity, the risk of chronic diseases can be reduced. Choices A, B, and C are not modifiable risk factors: Age is a non-modifiable factor, gender is a biological characteristic, and genetic predisposition is inherent and cannot be altered.

Correct Answer: D

Rationale: Conducting a windshield survey is the best strategy for the nurse to obtain an overview understanding of the student body. This method allows the nurse to observe the community, its resources, potential health hazards, and demographic information. Reviewing health records (Choice A) would provide detailed health information but not an overview of the student body. Talking with the parent-teacher association (Choice B) may offer insights but not a comprehensive overview. Sending a survey form to parents (Choice C) may provide specific information but may not capture a broad understanding of the student body.
