Chest X-ray

Complete blood count (CBC)

Pulmonary function tests (PFTs)

Electrocardiogram (ECG)

Answer and Explanation

The Correct Answer is C

A) Incorrect. Chest X-rays can provide information about the lungs but are not the primary diagnostic tool for assessing lung function in COPD.

B) Incorrect. A complete blood count (CBC) may reveal signs of infection or anemia but does not assess lung function.

C) Correct. Pulmonary function tests (PFTs), such as spirometry, are the primary diagnostic tool for assessing lung function in COPD. They measure parameters like forced expiratory volume in one second (FEV1) and forced vital capacity (FVC).

D) Incorrect. An electrocardiogram (ECG) is used to assess the electrical activity of the heart and is not a primary tool for diagnosing COPD.
