How should you apply a bandage to an injury?

Applying a bandage from the distal to proximal end of the injury is the correct approach because it promotes proper blood circulation and lymphatic flow, which can aid in the healing process. This technique ensures that blood can continue to flow towards the injury site, reducing the risk of constriction and potential complications such as swelling or tissue damage.

When bandaging, starting at the furthest point from the heart (distal) and moving towards the heart (proximal) can help ensure that the bandage doesn’t restrict circulation. It also can help in maintaining effective pressure on the wound while securing the dressing in place, which is essential for controlling bleeding and preventing infection.

The other approaches don't support optimal healing or may risk hindering circulation. For instance, bandaging side to side could leave gaps or areas where the wound isn't adequately covered. Additionally, wrapping in a circular motion might not provide uniform pressure or could lead to uneven distribution of the bandage, again jeopardizing circulation and overall effectiveness in protecting the injury.
