Which statement correctly describes how the sponge should be prepared before placement in NPWT?

• A. Trim sponge to fit entire wound bed but not overflow
• B. Use a full-size sponge that fills the wound
• C. Layer multiple sponges
• D. Use the smallest possible sponge to cover only the center

Answer: (A)

In NPWT, the dressing materials must be prepared so the negative pressure is transmitted evenly across the wound bed while protecting surrounding skin. The sponge should be trimmed to fit the entire wound bed so it makes contact with all wound surfaces, but it should not extend beyond the wound margins. When the sponge matches the wound precisely, suction is distributed uniformly, drainage is facilitated, and the periwound skin remains protected from maceration or injury. If the sponge overfills the wound or fills it completely to the edges, it can create dead space, disrupt the seal, promote leakage, and irritate surrounding tissue. Layering multiple sponges or using a tiny sponge that only covers the center can lead to uneven pressure and inadequate drainage, leaving parts of the wound unmanaged. So trimming the sponge to fit the wound bed without overflow provides consistent contact, effective suction, and protection of the surrounding skin.
