How should you use an occlusive dressing to treat a wound?

• A. Place over the wound and seal on three sides to prevent air entry while allowing venting on one side
• B. Seal completely on all four sides
• C. Leave uncovered for air to circulate
• D. Apply directly to skin without dressing first

Answer: (A)

Occlusive dressings keep the wound moist and protected while minimizing contamination, but you still want to prevent air from entering from all around. Sealing the dressing on three sides with one edge left open creates a one-way vent. That vent lets air and any drainage escape, reducing the risk of pressure buildup, while the majority of the wound remains covered by a nonporous barrier. Sealing all four sides traps air and moisture, which can lead to pressure, discourages drainage, and may increase infection risk. Leaving the wound uncovered fails to protect it or maintain a moist healing environment, and applying dressing directly to skin without any cover leaves the wound exposed.
