What material is commonly used in the secondary bandage layer to provide additional absorption?

The correct answer is gauze because it is a highly absorbent material that is often used in secondary bandage layers. In veterinary medicine, gauze is particularly effective at soaking up any exudate from a wound, which helps to keep the wound area clean and dry, promoting better healing. This absorbent quality is crucial in managing and supporting the primary dressing underneath, as it helps to prevent seepage and contamination.

While adhesive tape is important for securing various layers of bandaging, it does not provide absorption. Elastic wrap can offer support and compression, making it useful in stabilizing injuries, but it does not absorb fluid. Foam is often used for cushioning and protecting wounds, but it lacks the absorbent properties that gauze provides. Therefore, gauze stands out as the material that effectively adds absorption to a secondary bandage layer.
