Question

When evaluating the pulmonary function test results for a COPD client, which one correlates to the mismatch of ventilation and perfusion associated with this diagnosis?

Answer 1

Answer:

The correct answer is B.

Explanation:

I had to look at the options so that I could solve the exercise correctly. The options are:

A) The forced vital capacity (FVC) is high.

B) The forced expiratory volume (FEV) is decreased.

C) Total lung capacity (TLC) is decreased.

D) Marked decrease in residual volume (RV).

The correct answer is option B. In people with chronic lung disease, FVC is decreased, FEV1.0 is decreased, and the ratio of FEV1.0 to FVC is decreased. Lung volume measurements indicate a large increase in VR, an increase in total lung Cc, and an elevation in the ratio of VR to TVC.

Have a nice day!
