How many sides of an improvised occlusive dressing are taped down?

• A. All 4
• B. 2
• C. 3
• D. 1

Answer: (A)

The key idea is creating a complete barrier over the wound to prevent air and moisture from entering, keeping the wound environment as sealed as possible. Taping down all four edges of an improvised occlusive dressing provides a tight, uniform seal with the surrounding skin, which helps keep contaminants out and the dressing from lifting or peeling during movement. While three-sided taping is sometimes taught for chest wounds to act as a flutter valve and allow air to escape, this item focuses on a fully occlusive cover, so securing all four sides is the best way to ensure the dressing remains sealed. Leaving any edge untaped could allow air or contaminants to seep in and compromise the dressing’s effectiveness.
