Which step should be taken if blood soaks through an initial dressing?

When blood soaks through an initial dressing, the appropriate response is to apply a second layer of gauze on top of the original dressing. This method helps to effectively control bleeding and allows for continued pressure on the wound. By placing a second dressing over the first, you maintain the necessary pressure to help stop the flow of blood while also providing additional absorption for the excess blood.

Using this technique is advantageous, as it does not disturb the initial dressing, which may already be adhering to the wound and aiding in clot formation. Changing the initial dressing too soon can disrupt any clot that may have begun to form, leading to increased bleeding. Therefore, adding a second layer is a critical step in managing the situation effectively while ensuring the first dressing remains in place as long as possible.
