What should you do after applying a field dressing to a bleeding wound on a casualty's forearm?

After applying a field dressing to a bleeding wound on a casualty's forearm, the next step is to apply a pressure dressing. This action is essential because a field dressing is primarily used to absorb blood and cover the wound, but it may not provide adequate pressure to effectively control bleeding. By applying a pressure dressing over the initial field dressing, you can help to compress the wound and reduce blood flow, thereby minimizing blood loss, which is critical in first aid scenarios.

Applying a pressure dressing promotes hemostasis, which is the process of stopping bleeding, and supports the healing process by stabilizing the wound. It ensures that the dressing remains securely in place and continues to manage any bleeding that may occur. In contrast, options such as leaving the dressing as is might result in continued bleeding, while applying ice is not a recommended practice for most wounds and could further complicate care. Monitoring vital signs is vital but not immediately after the application of the dressing; it should be a part of the overall assessment and care as you continue to monitor the casualty's condition.
