When performing postural drainage on a client with chronic obstructive pulmonary disease (COPD), which approach should the nurse use?

Perform the drainage immediately after meals.

Explain that the client may be placed in five positions.

C. Instruct the client to breathe shallow and fast.

Answer and Explanation

The Correct Answer is B

B. Postural drainage involves placing the client in various positions to help drain secretions from different lobes of the lungs. There are typically five standard positions: head-down, head-up, on the side with the affected lung uppermost, on the side with the affected lung lowermost, and lying prone.

A. Performing postural drainage immediately after meals is not recommended because it can increase the risk of vomiting or aspiration, especially in individuals with chronic obstructive pulmonary disease (COPD) who may already have compromised lung function.

C. In postural drainage, the client is typically instructed to breathe deeply and slowly to maximize the effectiveness of the technique.

D. While ABGs may be necessary for monitoring respiratory status in clients with COPD, they are not specifically required prior to performing postural drainage.
