For open chest wounds, which dressing is appropriate to use?

• A. Open Chest wound
• B. Dry dressing
• C. Wet dressing
• D. Occlusive dressing

Answer: (D)

Sealing the wound to prevent air from entering the chest is essential. An open chest wound creates a pathway for air to be sucked into the pleural space during inhalation, which can cause or worsen a pneumothorax. An occlusive dressing provides an airtight seal over the wound, reducing the chance of air entering while still allowing air to escape if needed when taped to three sides (a flutter valve effect). A dry or wet dressing would not form a true seal, so they fail to prevent air entry. Simply noting the wound as open isn’t a dressing; the goal is to apply an occlusive covering to protect the chest.
