C) Correct. A sputum culture and sensitivity test helps identify specific bacteria or pathogens present in the sputum, which can guide antibiotic therapy if needed.
D) Incorrect. The test for measuring oxygen and carbon dioxide levels in the blood is typically done through arterial blood gases (ABG) rather than a sputum culture.
Explanation
A) Incorrect. Imaging studies, such as chest X-rays or CT scans, are not used to assess lung function or airflow; they provide structural information.
B) Incorrect. Identifying specific pathogens is typically done through sputum cultures or other microbiological tests, not imaging studies.
C) Correct. Imaging studies can be valuable in confirming or ruling out other lung conditions that may have similar symptoms to COPD, but they are not the primary diagnostic tool for COPD.

Explanation
A) Incorrect. While ABG tests provide information about blood gases, they do not directly evaluate lung function and airflow.
B) Correct. Arterial blood gas (ABG) tests measure the levels of oxygen and carbon dioxide in the blood, which can help assess respiratory function and acid-base balance.
C) Incorrect. ABG tests do not directly assess for the presence of respiratory infections; they focus on blood gas parameters.
D) Incorrect. Identifying specific bacteria causing respiratory symptoms is typically done through sputum cultures and sensitivity tests, not ABG tests.
Explanation
A) Correct. While a chest X-ray cannot diagnose COPD directly, it can reveal structural abnormalities and rule out other lung conditions, helping to confirm the presence and severity of COPD.
B) Incorrect. Chest X-rays focus on providing structural information about the lungs and are not used to evaluate lung function or airflow.
C) Incorrect. Identifying specific pathogens causing respiratory symptoms is typically done through microbiological tests, not chest X-rays.
D) Incorrect. The test for measuring oxygen and carbon dioxide levels in the blood is typically done through arterial blood gas (ABG) analysis, not a chest X-ray.
