12. An improvised che st seal should be taped down on three sides of the wound.This ensures that A. air can enter and leave the lung as needed through the gap in the chest seal B. the wound will not get infected C. objects will not fall into the wound D. air can escape from inside the lung cavity but cannot re -enter

Answer 1

D. Air can escape from inside the lung cavity but cannot re-enter.

Answer 2

## Step 1The problem is about the correct application of an improvised chest seal in a medical emergency. The chest seal is a critical tool used to prevent air from entering the pleural space, which can lead to a tension pneumothorax. This condition is a life-threatening situation where air enters the pleural space, causing the lung to collapse.## Step 2The chest seal is applied by taping down on three sides of the wound. This leaves one side open. The purpose of this is to allow air to escape from the lung cavity, but prevent it from re-entering.## Step 3The other options, such as allowing air to enter and leave the lung as needed, preventing infection, or preventing objects from falling into the wound, are not the primary reasons for taping down the chest seal on three sides.
