Answer 1

The most important, immediate step in the management of an open pneumothorax is applying an occlusive dressing.

Step-by-step explanation:

The most important, immediate step in the management of an open pneumothorax is applying an occlusive dressing. An open pneumothorax, also known as a sucking chest wound, occurs when there is a hole in the chest wall that allows air to enter the pleural space. By applying an occlusive dressing, such as plastic wrap or a specialized chest seal, over the wound, it creates a seal that prevents air from entering and allows the lung to re-expand. This helps to restore normal breathing and prevent further complications.
