Chest X-ray

Complete blood count (CBC)

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.

A. "The hallmark symptom of COPD is a persistent cough with blood-tinged sputum." B. "It's characterized by severe chest pain, especially during deep breaths." C. "Shortness of breath, especially during physical activity, is the hallmark symptom of COPD." D. "The primary symptom is a high fever and chills."
