What technique should a medical assistant use when bandaging a wound with a roller bandage?

When applying a roller bandage to a wound, wrapping from distal to proximal is the correct technique because it helps facilitate blood flow back to the heart, reducing the risk of constriction or impaired circulation. This method allows for better support of the injured area while also aiding in the reduction of swelling that can occur after an injury.

Using this technique ensures that the bandage applies gentle pressure to the wound, which can help control bleeding and promote healing without cutting off blood supply. It’s essential for the bandage to maintain circulation in the extremities, and wrapping in this direction adopts a more functional approach to managing the injury.

The other techniques mentioned would not align with best practices for wound care and can lead to complications, such as improper blood flow, increased swelling, or delayed healing. For instance, wrapping tightly might cause additional swelling or tissue damage, while leaving the wound exposed does not provide the appropriate protection or support needed for healing.
