Question

What diagnostic tests are appropriate to diagnose a client with chronic obstructive pulmonary disease (COPD)?

1) Sweat test
2) Arterial blood gases
3) Chest x-ray
4) Ventilation-perfusion testing
5) CBC with differential

Answer 1

To diagnose COPD, appropriate diagnostic tests include arterial blood gases, chest x-ray, and ventilation-perfusion testing.

Step-by-step explanation:

To diagnose a client with chronic obstructive pulmonary disease (COPD), the following diagnostic tests are appropriate:

1. Arterial blood gases: This test measures the levels of oxygen and carbon dioxide in the blood, which can help determine the severity of COPD.
2. Chest x-ray: This imaging test can show abnormalities in the lungs, such as emphysema or chronic bronchitis, which are associated with COPD.
3. Ventilation-perfusion testing: This test evaluates the airflow and blood flow in the lungs, providing additional information about lung function.

Sweat test and CBC with differential are not typically used for diagnosing COPD. The sweat test is used to diagnose cystic fibrosis, and CBC with differential is a general blood test that may not specifically indicate COPD.
