When should the transparent film dressing be changed in relation to wound fluid extension?

1. When the fluid reaches the wound edges.

2. When it starts to peel off.

3. When it shows signs of infection.

4. When fluid extends beyond the periwound skin.

The correct answer is: When fluid extends beyond the periwound skin.

The timing for changing a transparent film dressing is best determined by the extent of wound fluid, specifically when fluid extends beyond the periwound skin. Transparent film dressings are designed to provide a barrier to moisture while still allowing for gas exchange and are particularly beneficial in managing superficial wounds. When fluid accumulates and extends beyond the periwound area, it indicates that the dressing is becoming saturated, which can compromise its protective function and the healing environment of the wound. If left unchanged, this can lead to maceration of the surrounding skin and increase the risk of infection. In contrast, waiting until the fluid reaches the wound edges may not address the potential for surrounding skin damage quickly enough. Likewise, changing the dressing when it starts to peel off or showing signs of infection can result in compromised healing and does not prioritize maintaining the ideal moisture balance for the wound surface. Thus, changing the dressing when fluid extends beyond the periwound skin is the most effective practice to promote optimal healing and protect the integrity of the surrounding area.
