Which position is contraindicated for a client after a left pneumonectomy?

1. Supine position

2. Prone position

3. Right lateral position

4. Lateral position

The correct answer is: Lateral position

After a left pneumonectomy, where the left lung is removed, the recommended positioning for the client is crucial for optimal respiratory function and comfort. The lateral position that would be contraindicated in this situation is the right lateral position. In this position, the client would be lying on their right side, which could compress the remaining lung and the mediastinal structures. After removal of the left lung, the body may shift the mediastinum towards the left, particularly after surgery. This shift can result in airway complications or impaired ventilation in the right lung if the patient is positioned on the side of the remaining lung. Additionally, positioning on the right side may hinder adequate lung expansion and decrease oxygenation levels, making it less than ideal for recovery. In contrast, supine or prone positions might allow for better distribution of blood flow and ventilation to the remaining lung, as they do not overly compress or restrict the functioning lung on the right side. Thus, understanding the effects of different positions on lung function post-pneumonectomy is vital to providing safe and effective care for the client.
