Blood analysis of a patient reveals an unusually high quantity of carboxyhemoglobin content. Which of the following conclusion is the most likely to be correct? The patient has been inhaling poliuted air containing unusually high content of

Options

A. Carbon disulphide
B. Chloroform
C. Carbon dioxide
D. Carbon monoxide

Answer

To solve the question regarding the unusually high quantity of carboxyhemoglobin in a patient's blood, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Carboxyhemoglobin**:
- Carboxyhemoglobin is formed when carbon monoxide (CO) binds to hemoglobin in the blood. This binding is irreversible and prevents hemoglobin from carrying oxygen effectively.

2. **Sources of Carbon Monoxide**:
- Carbon monoxide is commonly produced from incomplete combustion of carbon-containing fuels. Common sources include car exhaust, burning of coal, gas stoves, and tobacco smoke.

3. **Analyzing the Patient's Condition**:
- The presence of high levels of carboxyhemoglobin suggests that the patient has been exposed to a significant source of carbon monoxide. This could be due to inhaling polluted air, particularly in environments where combustion occurs.

4. **Conclusion**:
- Given the context of the question, the most likely conclusion is that the patient has been inhaling polluted air containing unusually high content of carbon monoxide.

5. **Selecting the Correct Answer**:
- Based on the analysis, the correct answer to the question is that the patient has been inhaling air with high levels of carbon monoxide.

### Final Answer:
The patient has been inhaling polluted air containing unusually high content of **carbon monoxide**.
